1 / 20 page  1 S2070 FIBRE CHANNEL/GIGABIT ETHERNET TRANSCEIVER March 7, 2001 / Revision G S2070 ® DEVICE SPECIFICATION FIBRE CHANNEL/GIGABIT ETHERNET TRANSCEIVER FEATURES • 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 APPLICATIONS • Workstation • Frame buffer • Switched networks • Data broadcast environments • Proprietary extended backplanes GENERAL DESCRIPTION The S2070 transmitter and receiver chip facilitates high speed serial transmission of data over fiber op- tic, 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-par- allel conversion, clock generation/recovery, and framing for block encoded data. The on-chip transmit PLL synthesizes the high-speed clock from a low- speed reference. The on-chip receive PLL performs clock recovery and data re-timing on the serial bit stream. The transmitter and receiver each support differential LVPECL compatible I/O for copper or fi- ber optic component interfaces with excellent signal integrity. Local loopback mode allows for system di- agnostics. The chip requires a +3.3 V power supply and dissipates approximately 620 mW under typical conditions. The S2070 can be used for a variety of applications including Fibre Channel, serial backplanes, and pro- prietary point-to-point links. Figure 1 shows a typical configuration incorporating the chip.
