Figure 10. Implementation of the PECL RX section
Implementation of the PECL TX section
PECL receiver
The data signals coming from the optical transceiver are in PECL format and need to be
converted to CMOS level before being transmitted to the data and clock recovery, and to the
digital portion.
The data is sampled by the optical transceiver, but the data stream is related to the clock of
the transmitting transceiver, so it needs to be recovered, re-sampled and aligned to the RX
clock.
This function and all the timing involved are assumed to be compatible with that currently
available for the 100TX (twisted pair), so no modifications are required for this circuit.
