Transmitter

This chapter shows how to configure and use each of the functional blocks inside the transmitter (TX). Each transceiver includes an independent transmitter, which consists of a PCS and a PMA. The following figure shows the functional blocks of the transmitter. Parallel data flows from the device logic into the TX interface, through the PCS and PMA, and then out the TX driver as high-speed serial data.

The key elements within the transceiver TX are:

1. TX Interface
2. TX 8B/10B Encoder
3. TX Synchronous Gearbox
4. TX Buffer
5. TX Buffer Bypass
6. TX Pattern Generator
7. TX Polarity Control
8. TX Fabric Clock Output Control
9. TX Phase Interpolator PPM Controller
10. TX Configurable Driver
11. TX Out-of-Band Signaling
