SN65LV1023A: Use of SN65LV1023A/SN65LV1224B as replacement for MAX9205/MAX9206 devices

Part Number: SN65LV1023A
Other Parts Discussed in Thread: SN65LV1224B,

Does anyone have any experience using SN65LV1023A and SN65LV1224B serializer/deserializer devices as replacements for MAX9205 and MAX9206 devices, which are now obsolete?

We currently use the Maxim parts in a short serial data link systems using a TCLK/REFCLK frequency of approximately 19.6MHz, so well within the frequency range of the TI parts..

Comparing the specifications, they look very close. We're aware of the difference in REFCLK tolerance (100ppm for the SN65LV1224B compared to 200ppm for the MAX9206) and there's also a small difference in threshold on the LVDS input, but we're wondering if anybody knows of any other differences in operation that might cause difficulty.

This is a relatively old product, so ideally we don't want to make major changes, but small hardware modifications if required to accommodate the SN65LV1023A and SN65LV1224B would be OK.

Best regards

Simon

    Hi Simon,

    I have not used those specific Maxim devices, but after looking at the datasheets, our devices look like they should be p2p replacements. However, I did notice that the Maxim devices spec a continuous short circuit duration on the output pins, whereas our device only allow 10 ms. Also, our devices have has slightly higher thermal derating, so keep that in mind if you are pushing max power for the Maxim devices in a hot environment. 

    Regards,

    Hi Matt

    Thanks for the confirmation and for the note about short circuit duration. Our LVDS outputs are routed via another device before they get to the outside world, so they shouldn't see any shorts due to incorrect connection.

    Feels like we should be OK.

    Regards

    Simon
