Instructions for Use:
Power Supply Connection: Connect the VDD pin to a stable power supply within the specified range of 1.65V to 3.6V. Ensure that the GND pins are properly grounded.
Signal Input: Connect your differential input signals to the appropriate input channels (IN0, IN1, IN2, IN3). Make sure to match the signal types as per the device specifications.
Selection Control: Use the SEL0 and SEL1 pins to control which input channel is selected for output. The selection logic is binary, where SEL1SEL0 = 00 selects IN0, 01 selects IN1, 10 selects IN2, and 11 selects IN3.
Output Handling: The output will be available on the OUTP and OUTN pins based on the selected input channel. Ensure that the receiving circuitry can handle the differential signal output.
PCB Layout Considerations: For optimal performance, keep signal traces as short as possible and use controlled impedance routing for high-speed signals. Place decoupling capacitors close to the VDD and GND pins.
Thermal Management: Although the device is designed for low power consumption, ensure adequate ventilation or cooling if operating at higher temperatures or data rates.
Testing and Validation: After assembly, verify the functionality using test patterns at various data rates to ensure correct operation.
