S2060

The following are the absolute maximum stress ratings for the S2060 device. Stresses beyond those listed may cause permanent damage to the device. Absolute maximum ratings are stress ratings only and operation of the device at the maximums stated or any other conditions beyond those indicated in the "Recommended Operating Conditions" of the document are not inferred. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The S2060 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 runs at 1250.0 Mbps data rates with an associated 10-bit data word.

The S2060 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 differential LVPECL compatible I/O for copper or fiber optic component interfaces with excellent signal integrity. Local loopback mode allows for system diagnostics.

The chip requires a +3.3 V power supply and dissipates typically 620 mW.The S2060 can be used for a variety of applications including Gigabit Ethernet, serial backplanes, and proprietary point-to-point links. Figure 1 shows a typical configuration incorporating the chip.
