| S2060 Gigabit Ethernet/Fibre Channel Transceiver Local loopback mode allows for system diagnostics. The chip requires a +3.3 V power supply and dissipates typically 620 mW. Product Brief PB2026_v0.01_10/26/05 - At a Glance - S2060 The S2060 can be used for a variety of applications including GE, FC, serial backplanes, and proprietary point-topoint links. Figure 1 shows a typical configuration incorporating the chip. Features * * * * 1250 MHz (Gigabit Ethernet) line rate 1062 MHz (Fibre Channel) line rate 531 MHz and 625 MHz half rate operation Functionally compliant to IEEE 802.3z Gigabit Ethernet and ANSI X3T11 Fibre Channel Specifications Receiver and Transmitter incorporates PLLs for clock/ data recovery and synthesis Continuous downstream clocking from receiver 10-bit parallel LVTTL compatible I/O interface Low-jitter serial LVPECL compatible interface Local loopback Drives 30 m of Twinax cable directly Single +3.3 V supply, 620 mW power dissipation 64 PQFP or TQFP package with Green/RoHS compliant lead free options Commercial and industrial temperature range Overview Description The S2060 transmitter and receiver chip facilitates high speed serial transmission of data over fiber optic, coax, or twinax interfaces. The device is functionally compliant with the requirements of the IEEE 802.3z Gigabit Ethernet (GE) and ANSI X3T11 Fibre Channel (FC) specifications and operates at the full rates of 1250.0 and 1062.5 Mbps data rates, respectively, with an associated 10-bit data word. The device also provides half rate operation at 625 and 531 Mbps. The chip provides parallel-to-serial and serial-to-parallel conversion, clock generation/recovery, and optional framing for 8B/10B encoded data. The on-chip transmit PLL synthesizes the high-speed clock from an external 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 differential LVPECL compatible I/O for copper or fiber optic component interfaces with excellent signal integrity. The S2060 transmitter and receiver provide serialization and deserialization (SERDES) functions for 8B/10B encoded data to implement a GE or FC interface. The sequence of transmitter and receiver functions are as follows: Transmitter Operations: 1. 10-bit parallel input 2. Parallel-to-serial conversion 3. Serial output Receiver Operations: 4. Clock and data recovery from serial input 5. Serial-to-parallel conversion 6. Frame detection 7. 10-bit parallel output The 10-bit parallel data input to the S2060 should be from a DC-balanced encoding scheme, such as that of the 8B/10B transmission code1, in which information to be transmitted is encoded 8 bits at a time into 10-bit transmission characters. * * * * * * * * * Gigabit Ethernet/ Fibre Channel Controller Optical Tx S2060 Optical Rx Optical Rx S2060 Optical Tx Gigabit Ethernet/ Fibre Channel Controller Figure 1.
