8 bit data bus to SPI

Other Parts Discussed in Thread: SN65LV1224B, SN65LV1023A, SN75LVDT1422

Hello.  I am looking for a bi-directional interface between an 8 bit data bus and SPI.  My only requirement is that the speed is 9 Mbps or greater.  Any help on what interfaces are available and where to find them would be very much appreciated.  Thank you

    Russell,

    The high speed interface portfolio does not have SPI specific serializers.  You may want to consider posting to the logic and linear forum for more specific feedback.  If there is some flexability in your design then some device options to consider are the following:

    - SN65LV1023A and SN65LV1224B (10bit LVDS Serializer/De-Srializer)

    - SN75LVDT1422 (14bit TX/RX LVDS transceiver)

    Both of the above devices are rated for much higher data rates than 9Mbps but may work if your application can support a bit higher data rate and if strict SPI signaling levels are not required.

     

    Thanks,
