Functional description Both transmission and reception stages are controlled either by the master clock of the microcontroller or by the on-chip reference oscillator connected to a crystal. This ensures the accuracy of the transmission carrier and the exact trimming of the digital filter, thus making the performance totally independent of application disturbances such as component spread, temperature, supply drift and so on. The interface with the power network is made by means of an LC network (see Figure 15). The device includes a power output stage that feeds a 120 dBV (RMS) signal on a typical 30 load. To reduce power consumption, the IC is disabled by a power-down input (pin PD): in this mode, the on-chip oscillator remains active and the clock continues to be supplied at pin CLK_OUT. For low-power operation in reception mode, this pin can be dynamically controlled by the microcontroller, see Section 8.4 "Power-down mode". When the circuit is connected to an external clock generator (see Figure 6), the clock signal must be applied at pin OSC1 (pin 7); OSC2 (pin 8) must be left open-circuit. Figure 7 shows the use of the on-chip clock circuit. All logic inputs and outputs are compatible with TTL/CMOS levels, providing an easy connection to a standard microcontroller I/O port. The digital part of the IC is fully scan-testable. Two digital inputs, SCANTEST and TEST1, are used for production test: these pins must be left open-circuit in functional mode (correct levels are internally defined by pull-up or pull-down resistors). 8.1 Transmission mode To provide strict stability with respect to environmental conditions, the carrier frequency is generated by scanning the ROM memory under the control of the microcontroller clock or the reference frequency provided by the on-chip oscillator. High frequency clocking rejects the aliasing components to such an extent that they are filtered by the coupling LC network and do not cause any significant disturbance. The data modulation is applied through pin DATA_IN and smoothly applied by specific digital circuits to the carrier (shaping). Harmonic components are limited in this process, thus avoiding unacceptable disturbance of the transmission channel (according to CISPR16 and EN50065-1 recommendations). A -55 dB Total Harmonic Distortion (THD) is reached when the typical LC coupling network (or an equivalent filter) is used. The DAC and the power stage are set in order to provide a maximum signal level of 122 dBV (RMS) at the output. The output of the power stage (TX_OUT) must always be connected to a decoupling capacitor, because of a DC level of 0.5VDD at this pin, which is present even when the device is not transmitting. This pin must also be protected against overvoltage and negative transient signals. The DC level of TX_OUT can be used to bias a unipolar transient suppressor, as shown in the application diagram (see Figure 15). Direct connection to the mains is done through an LC network for low-cost applications. However, an HF signal transformer could be used when power-line insulation has to be performed.

All rights reserved. 5 of 29 TDA5051A NXP Semiconductors Home automation modem Remark: In transmission mode, the receiving part of the circuit is not disabled and the detection of the transmitted signal is normally performed. In this mode, the gain chosen before the beginning of the transmission is stored, and the AGC is internally set to -6 dB as long as DATA_IN is LOW. Then, the old gain setting is automatically restored. 8.2 Reception mode The input signal received by the modem is applied to a wide range input amplifier with AGC (-6 dB to +30 dB). This is basically for noise performance improvement and signal level adjustment, which ensures a maximum sensitivity of the ADC. An 8-bit conversion is then performed, followed by digital band-pass filtering, to meet the CISPR16 normalization and to comply with some additional limitations met in current applications. After digital demodulation, the baseband data signal is made available after pulse shaping. The signal pin (RX_IN) is a high-impedance input which has to be protected and DC decoupled for the same reasons as with pin TX_OUT. The high sensitivity (82 dBV) of this input requires an efficient 50 Hz rejection filter (realized by the LC coupling network), which also acts as an anti-aliasing filter for the internal digital processing; (see Figure 15). 8.3 Data format 8.3.1 Transmission mode The data input (DATA_IN) is active LOW: this means that a burst is generated on the line (pin TX_OUT) when DATA_IN pin is LOW. Pin TX_OUT is in a high-impedance state as long as the device is not transmitting. Successive logic 1s are treated in a Non-Return-to-Zero (NRZ) mode, see pulse shapes in Figure 8 and Figure 9. 8.3.2 Reception mode The data output (pin DATA_OUT) is active LOW; this means that the data output is LOW when a burst is received. Pin DATA_OUT remains LOW as long as a burst is received. 8.4 Power-down mode Power-down input (pin PD) is active HIGH; this means that the power consumption is minimum when pin PD is HIGH. Now, all functions are disabled, except clock generation. TDA5051A Product data sheet All information provided in this document is subject to legal disclaimers.

When handling ensure that the appropriate precautions are taken as described in JESD625-A or equivalent standards. 16. Soldering of SMD packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 "Surface mount reflow soldering description". 16.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 16.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: * Through-hole components * Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: * * * * * * Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus SnPb soldering 16.3 Wave soldering Key characteristics in wave soldering are: TDA5051A Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 23 of 29 TDA5051A NXP Semiconductors Home automation modem * Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave * Solder bath specifications, including temperature and impurities 16.4 Reflow soldering Key characteristics in reflow soldering are: * Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 25) than a SnPb process, thus reducing the process window * Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board * Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 9 and 10 Table 9. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 < 2.5 235 220 2.5 220 220 Table 10.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 25.
