Switching Waveforms for the CYV15G0404DXB HOTLink II Receiver
Notes
34. The TXCLKOx output remains at the character rate regardless of the state of TXRATE and does not follow the duty cycle of REFCLKx±.
35. The rising edge of TXCLKOx output has no direct phase relationship to the REFCLKx± input.
36. TXERRx is synchronous to RXCLKx only when RXCLKx is selected as REFCLK.
