Detailed Description 4.1 Serial Data Input The GS2989 features a differential input buffer with on-chip 100 differential termination. The serial data input signal is connected to the DDI and DDI input pins of the device. Input signals can be single-ended or differential, DC or AC-coupled. The serial data input buffer is capable of operation with any binary coded signal that meets the input signal level requirements, in the range of 270Mb/s to at least 2.97Gb/s. The input circuit is self-biasing to allow for simple AC or DC-coupling of input signals to the device. 4.2 Input Trace-equalization The GS2989 features fixed trace-equalization to compensate for PCB trace dielectric losses. NOTE: This feature is not available in SD mode, and therefore trace-equalization must be disabled when operating in this mode. The trace-equalization has two settings, OFF and ON. ON invokes a typical 3dB gain value at 1.5GHz. This value is optimized for compensating the high-frequency losses associated with approximately 10 inches of 5-mil stripline in FR4 material. Table 4-1: Input Trace-Equalization EQ_EN Function 0 Typical 3dB Trace Equalization 1 Trace Equalization OFF Floating Trace Equalization OFF 4.3 Serial Data Output The GS2989 features dual current-mode differential output drivers capable of driving up to 1800mVpp single-ended into a 1m length of 75 cable terminated at both ends. The output signal amplitude or swing is user configurable using an external RSET resistor. The SDO1/SDO1 and SDO2/SDO2 pins of the device provide the serial data outputs. 4.3.1 Slew Rate Selection (Rise/Fall Time Requirement) The GS2989 supports two user-selectable output slew rates. GS2989 Dual-Slew-Rate, Dual-Output Cable Driver with 3Gb/s Capability Data Sheet 52133 - 4 December 2010 10 of 19 Control of the slew rate is determined by the setting of the SD/HD input pin. Table 4-2: Slew Rate Selection SD/HD Rise/Fall Time 0 SMPTE 424M & 292M compliant 1 SMPTE 259M compliant Floating SMPTE 259M compliant 4.4 Output Disable The GS2989 supports an output disable function for each serial data differential output. Control of this function is determined by the setting of the DISABLE1 and DISABLE2 control pins. The serial output disables (DISABLE1 and DISABLE2), disable power to the current mode serial data output drivers. When asserted LOW, the SDO/SDO output drivers are powered-down. Table 4-3: Output Disable DISABLE1 DISABLE2 SDO1/SDO1 SDO2/SDO2 0 0 or Floating 0 1 High-Impedance Operational 1 or Floating 0 or Floating Operational High-Impedance 1 or Floating 1 Operational Operational Floating Floating Operational High-Impedance All Chip Power Down When DISABLE1 and DISABLE2 are driven LOW simultaneously, the entire device is powered down, and the power consumption is minimized. 4.5 Output Signal Presence Indicator (OSP) The GS2989 supports an output signal presence indicator function. The output signal presence pin (OSP) is an active-low output that indicates when a valid output signal has been detected at the pre-driver output. The output signal presence function measures signal-edge energy to indicate that the pre-driver to the serial data outputs is toggling.

For an 800mVp-p output with a nominal 7% tolerance, a value of 750 is required. A 1% SMT resistor should be used. The RSET resistor is part of an internal DC feedback loop in the GS2989. The resistor should be placed as close as possible to the RSET pin, and connected directly to the VCC plane (traces/wires may cause instability). In addition, the PCB capacitance should be minimized at this node by removing the PCB groundplane beneath the RSET resistor and the RSET pin. NOTE: Care should be taken when considering layout of the RSET resistor. Please refer to Section 5.1 for more details. 2.0 1.75 1.5 VOUT (V) 1.25 1.0 0.75 0.5 0.25 0.250 0.500 0.750 1.0 1.25 1.5 RSET (k) Figure 4-1: VOUT vs. RSET GS2989 Dual-Slew-Rate, Dual-Output Cable Driver with 3Gb/s Capability Data Sheet 52133 - 4 December 2010 12 of 19 In order to determine the best starting value for Rset, the following formula should be used: Rset = 8*(Rtrm/VoutppSE) Where VoutppSE is in Volts, and both resistances are in . Rtrm is the value of the termination resistors, which should be equal to the characteristic impedance of the cable, and is typically 75. The cable must be short (1m), and terminated at both ends for the formula to be valid. Example: For a 75 cable, Rtrm = 75 (at both ends), VoutppSE = 800mV Rset = 8*(75/0.8) = 750 This formula is not valid for long, unterminated, or improperly terminated cables. This formula should be considered as a starting point, and actual swing values may vary based on layout. Also, for large output swings (>1040mV), smaller Rset values may be required in order to achieve the desired output swing level at HD and 3G data rates. Table 4-5: Typical RSET Values Output Swing (mV) RSET () 1800* 332 800 750 500 1210 *NOTE: In order to generate output swings greater than 1040mV, VCC_TERM must be connected to a 5V supply. 4.7 Output Return Loss Measurement The GS2989 has a feature which allows users to measure ORL reliably while the device is still powered. The device can be put into a BALANCE mode which prevents the outputs from toggling while the device is powered on, allowing the ORL to be measured while the device is still powered. When EQ_EN is LOW while SD/HD is HIGH, the device goes into BALANCE mode. This mode is used during ORL measurement, disabling the AC signal path of the device without powering it down. When in BALANCE mode, the device produces equal pull-down currents in both differential shoulders of both serial data differential outputs, effectively stopping all outputs at the output common mode voltage level. Gennum recommends using BALANCE mode when measuring ORL with 2.5V termination voltage.

Application Information 5.1 PCB Layout Special attention must be paid to component layout when designing serial digital interfaces for HDTV. An FR-4 dielectric can be used, however, controlled impedance transmission lines are required for PCB traces longer than approximately 1cm. Note the following PCB artwork features used to optimize performance: * The PCB trace width for HD rate signals is closely matched to SMT component width to minimize reflections due to changes in trace impedance * The PCB ground plane is removed under the GS2989 output components to minimize parasitic capacitance (NOTE: care should be taken, as removing too much of the plane will make the system susceptible to EMI) * The PCB ground plane is removed under the GS2989 RSET pin and resistor to minimize parasitic capacitance. The RSET resistor should be directly connected to the VCC plane * Input and output BNC connectors are surface mounted in-line to eliminate a transmission line stub caused by a BNC mounting via high-speed traces * High-speed traces are round-curved (rather than 45 or 90 angles) to minimize impedance variations due to change of PCB trace width NOTE: For more recommendations on Trace Lengths, ORL Inductor Values and other PCB Layout Considerations, please refer to Gennum's GS2989 Design Guide (Doc ID 52070).
