Hewlett-Packard HDMP-1637A
The HDMP-1637A transceiver is a single silicon bipolar integrated circuit packaged in a plastic QFP package. It provides a low-cost, low-power physical layer solution for 1250 MBd Gigabit Ethernet or proprietary link interfaces. It provides complete Serialize/ Deserialize (SerDes) for copper CAUTION: As with all semiconductor ICs, it is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by electrostatic discharge (ESD).| Part No. | HDMP-1637A |

FEATURES
● IEEE 802.3z Gigabit Ethernet Compatible, Supports 1250 MBd Gigabit Ethernet● Based on X3T11 “10 Bit Specification”
● Low Power Consumption
● 10 mm 64-pin PQFP Package
● Transmitter and Receiver Functions Incorporated onto a Single IC
● 5-Volt Tolerant I/Os
● 10 Bit Wide Parallel TTL Compatible I/Os
● Single +3.3 V Power Supply
● Differential PECL Clock Inputs
● 2 kV Human Body ESD Protection on all Pins transmission, incorporating both the Gigabit Ethernet 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. This parallel data is latched into the input register of the transmitter section on the rising edge of the 125 MHz reference clock (used as the transmit byte clock).
