STLC60133 XDSL LINE DRIVER PRELIMINARY DATA LOW NOISE : 4nV/ H z HIGH PEAK OUTPUT CURRENT: 500 mA HIGH SPEED - 140MHz Gain Bandwidth - 30MHz Gain Flatness - 400 V/us Slew Rate HTSSOP28 LOW POWER OPERATION ORDERING NUMBER: STLC60133 - 5V to 15V Voltage Supply - 12.5 mA/Amp (typ) Supply current Temperature Range: -40C to +85C - Power reduced Current LOW SINGLE TONE DISTORTION THERMAL AND OVERLOAD PROTECTION HTSSOP28 PACKAGE -40 TO +85C OPERATING RANGE Two digital pins (PWDN0 and PWDN1) allow the driver to work in full performance mode, in low-power mode or two intermediate bias states. DESCRIPTION The low-power mode biases the output stage in order to provide a low impedance at the amplifier outputs for back termination. The STLC60133 is a dual amplifier featuring a high slew rate and a large bandwidth optimized for XDSL applications. The device is available in a HTSSOP 28 pin package (4x9 mm) with an exposed leadframe. The STLC60133 is designed optimizing bandwidth and distortion performances. For proper device operating it is necessary to work with a gain level greater than 15.6dB. Thanks to its small package this line driver is suitable for high density ADSL line card. Typical differential gain is normally +27dB, while typical common mode gain is 15.6dB Figure 1. BLOCK DIAGRAM -VS IN1N - IN1P + +VS Op1 OUT1 PWDN0 PWDN1 LOGIC TH DETCT.

According to the different XDSL application (both site CO and CPE), different bias levels can be chosen maintaining good MTPR performances. In the following table are shown the bias levels versus the PWDN values. PWDN1 PWDN0 Bias Level 1 1 100% 1 0 60% 0 1 40% 0 0 25% (low Zout but not OFF) X X Full OFF (High Zout via 250uA pulled out of BIAS pin) 3/9 STLC60133 The bias level is programmed by the TTL logic level applied to the PWDN pins. The DGND pin is the logic ground reference for the PWDN pins. For normal operation the BIAS pin shall be left open. The BIAS control pin can be used to adjust the internal biasing and thus the quiescent current. By pulling out a current of 0A to 200A, the quiescent current can be adjusted from 100% (full ON) to a full OFF condition. However, considering the internal parameter spread to full shutdown the STLC60133 is recommended to pull down a 250A current from the BIAS pin. In the following figure is shown an implementation of a complete amplifier shutdown. To partially reduce the internal biasing also the PWDN pins can be used. Figure 2. Logic drive of bias pin for complete Amplifier Shutdown. 3.3V R1 BIAS R2 50K STLC60133 R1 = 47K for 12V R1 = 22K for 6V D01TL492 THERMAL SHUTDOWN A thermal protection is embedded in the STLC60133. In case of thermal overload the device is shut down at 160C and returns to normal operation when the temperature becomes lower than 145C. During the thermal shutdown the voltage at the BIAS pin goes to the DGND rail; when the device returns to the normal operation the voltage at the BIAS pin goes to the positive rail. In this condition the BIAS pin can be used as thermal overload indicator. MAXIMUM POWER DISSIPATION Maximum Junction Temperature allowed for proper device operation is T j = 140C. A Typical Thermal Resistance Junction to ambient of 29C/W can be obtained mounting the device on a 4 layer board whithin 10 square inches of copper and having the exposed pad contacting a proper copper area . It shall be noted that the exposed pad of the device is electrically connected to the VSS negative supply. Figure 3.
