Note 1:
TCK and CLD are generated on chip and provide the data clocks for the CD port and the transmit section of the
DV port. RCK, also generated on chip, is extracted from the receive data and only clocks out the data at the D
o
output
and may be skewed with respect to TCK due to end-to-end delay.
Note 2:
At the slave end TCK is phase locked to RCK.
The rising edge of TCK will lead the rising edge of RCK by approximately 90
