RocketIO™ X Transceiver User Guide
UG035 (v1.5) November 22, 2004
Variable speed full-duplex transceiver, allowing 2.488 Gb/s to 10.3125 Gb/s baud
transfer rates, including specific baud rates used by various standards (listed in
Table 1-2, page 27)
Depending on the Virtex-II Pro X device, from 8 to 20 transceiver modules on an FPGA
Monolithic clock synthesis and clock recovery system, eliminating the need for
external components
Automatic lock-to-reference function
Serial output differential swing that can be programmed between 200 mV to 1600 mV
(peak-peak), allowing compatibility with other serial system voltage levels
Levels of programmable emphasis from 0 to 500% (not all emphasis and swing
combinations can be attained)
Receiver equalization
AC and DC coupling
On-chip termination of 50Ω (eliminating the need for external termination resistors)
Pre and post driver serial and parallel TX to RX internal loopback modes for testing
operability
Programmable comma detection to allow for any protocol and detection of any 10-bit
character
8B/10B and 64B/66B encoding blocks
