HDMP-1034A

The HDMP-1034A receiver is used together to build a high-speed data link for point-to-point communication.The HDMP-1034A silicon bipolar transmitter and receiver chips is housed in standard plastic 64 pin PQFP packages.From the user's viewpoint, these products can be thought of as a "virtual ribbon cable" interface for the transmission of data and control words. A parallel word loaded into the Tx (transmitter) chip is delivered to the Rx (receiver) chip over a serial channel and is then reconstructed into its original parallel form.The channel can be either a coaxial copper cable or optical link.

Features of the HDMP-1034A are:(1)3.3 V supply, low power dissipation 660 mW Tx, 792 mW Rx; (2)on-chip encode/decode using conditional inversion master transition (CIMT) protocol; (3)1:N broadcast ready configurable receiver inputs allow multi-point data broadcast using a single transmitter; (4)parallel automatic Synchronization System (PASS) allows receiver to read recovered words with local reference clock; (5)robust simplex mode; (6)wide range serial rate 260-1400 Mbaud (user selectable).The serial data rate of the Tx/Rx link is selectable in three ranges and extends from 208 to 1120 Mbit/s. This translates into an encoded serial rate of 260 to 1400 MBaud. The parallel data interface is 16 bit TTL. A flag bit is also present and can be used as an extra 17th bit under the user's control. This bit can be used as an even or odd word indicator for dual-word transmission.

The absolute maximum ratings of the HDMP-1034A can be summarized as:(1)supply voltage:-0.5 to 5.0V;(2)storage temperature:-65 to +150;(3)junction temperature:0 to +150 ;(4)TTL input voltage:-0.7 to 5.5V;(5)H50 input voltage:2.0 to Vcc V;(6)maximum assembly temperature (10 seconds maximum) :+260.An external serial clock can be used instead of the VCO clock.This is accomplished by setting TCLKENB high and applying a serial rate clock to TXCLK.Note that this mode is used for diagnostic purposes only.The HDMP-1034A (Rx) is implemented monolithically in a high performance 25 GHz ft silicon bipolar process. The Rx accepts a serial stream of 20 bit conditional invert withmaster transition (CIMT) line code words and outputs parallel 16 bit/17 bit data words or 14 bit Control Words.
