Hi,

I have a trace which connects in daisy-chain from 1 driver(transceiver) to
6 receivers ( 2 ASICs (BGA type), 2 ROMs, 1 flash memory and 1 transceiver).
The connecting sequence is 1) ASIC1, 2) ASIC2, 3), transceiver, 4) ROM1, 5)
ROM2, 6) Flash memory.
My problem is the simulation result shows reflection occurs at the
receiver(non-monotonic waveform) nearest to the driver. Is it a good idea
to put a pulldown resistor at that receiver(resistor value = Zo)?

I welcome any suggestions or advices on this matter. Thank you.

Regards,
KT.THAM
