1062 Mbps (Fibre Channel) line rates 1250 Mbps (Gigabit Ethernet) line rates Half and full VCO output rates Functionally compliant to IEEE 802.3z Gigabit Ethernet Specification and the ANSI X3T11 Fibre Channel Specification Transmitter incorporating phase-locked loop (PLL) clock synthesis from low speed reference Receiver PLL provides clock and data recovery 10-bit parallel TTL compatible interface Low-jitter serial LVPECL compatible interface Local loopback Single +3.3 V supply, 620 mW power dissipation 64 PQFP package Continuous downstream clocking from receiver Drives 30 m of Twinax cable directly
The S2070 transmitter and receiver chip facilitates high speed serial transmission of data over fiber optic, coax, or twinax interfaces. The device conforms to the requirements of the IEEE 802.3z Gigabit Ethernet Specification and the ANSI X3T11 Fibre Channel specification, and runs at 1062 Mbps or 1250 Mbps data rates with an associated 10-bit data word. The chip provides parallel-to-serial and serial-to-parallel conversion, clock generation/recovery, and framing for block encoded data. The on-chip transmit PLL synthesizes the high-speed clock from a lowspeed reference. The on-chip receive PLL performs clock recovery and data re-timing on the serial bit stream. The transmitter and receiver each support differentia……
