HDMP-1646A

Gigabit Ethernet and Fibre Channel SerDes ICs Technical Data Features IEEE 802.3z Gigabit Ethernet Compatible ANSI x3.230-1994 Fibre Channel Compatible (FC-O) Supports Serial Data Rates of 1062.5 MBd (Fibre Channel) & 1250 MBd (Gigabit Ethernet) Low Power Consumption, 630 mW Typical Transmitter and Receiver Functions Incorporated onto a Single IC Three Package Sizes Available: – 10 mm TQFP (HDMP-T1636A) – 10 mm PQFP (HDMP-1636A) – 14 mm PQFP (HDMP-1646A) 10-Bit Wide Parallel TTL Compatible I/Os Single +3.3 V Power Supply 5-Volt Tolerant I/Os 2 kV ESD Protection on All Pins HDMP-1636A Transceiver HDMP-1646A Transceiver HDMP-T1636A Transceiver Description The HDMP-1636A/46A/T1636A transceiver is a single integrated circuit packaged in a plastic QFP package. It provides a low-cost, low-power physical layer solution for 1250 MBd Gigabit Ethernet, 1062.5 MBd Fibre Channel, and proprietary link interfaces. It provides complete Serialize/ Deserialize (SerDes) for copper transmission, incorporating the Gigabit Ethernet/Fibre Channel transmit and receive functions into a single device. This chip is used to build a high speed interface (as shown in Figure 1) while minimizing board space, power and cost. It is compatible with the IEEE 802.3z specification. The transmitter section accepts 10-bit wide parallel TTL data and serializes this data into a high speed serial data stream. The parallel data is expected to be “8B/10B” encoded data, or equivalent.
