A good PCB layout for the HCPL-2630 involves keeping the input and output circuits separate, using a ground plane, and minimizing the length of the input and output traces. TI provides a recommended PCB layout in the application note SLUA271.
To ensure proper biasing, connect the VCC pin to a stable 5V power supply, and the GND pin to a solid ground plane. The input pins (An and Ap) should be biased to a voltage between 0.5V and 2.5V, and the output pins (Vo) should be biased to a voltage between 0.5V and 5V.
The HCPL-2630 can handle data rates up to 10 Mbps, but the actual data rate may be limited by the specific application and the quality of the input signal.
The HCPL-2630 requires a differential input signal with a minimum amplitude of 100 mV. The input signal should be conditioned to ensure it meets this requirement, using components such as resistors, capacitors, and op-amps as needed.
The typical propagation delay of the HCPL-2630 is around 100 ns, but this can vary depending on the specific application and operating conditions.
