We are using A10 transceiver blocks and we use CML and High Speed Differential I/O pin standards interchangeably, since these two standards seem to us to basically describe the same thing. Could you please explain the differences between CML and High Speed Differential I/O, so we could confirm our approach?
Thank you for Your help
Yes your understanding is correct. In term of the A10 XCVR, when you use CML and High Speed Differential I/O, the TX and RX specs are actually the same. The only difference is that the A10 TX only support High Speed Differential I/O standard but RX can support High Speed Differential I/O, CML , Differential LVPECL , and LVDS standards.
Please let me know if there is any concern. Thank you.
For further details on the A10 TX and RX specs, you may also refer to the Receiver Specifications and Transmitter Specifications tables in the A10 datasheet. Thank you.
