PRODUCT BRIEF

The M08045 is a serial digital video reclocker with integrated trace

equalization, automatic rate detect (ARD) circuitry, and a 4:1 mux at

the input. It operates at data at 2.97 Gb/s, 1.485 Gb/s, and 270

Mb/s. The device has an input jitter tolerance (IJT) of greater than

0.6 unit intervals (UI) and can provide retimed serial outputs with

very low output jitter. The reclocker requires a single, external,

27MHz crystal, which is used as the reference clock for all four

channels. It includes per lane analog input equalization for up to 40"

of FR4 trace and two connectors in addition to output de-emphasis.

This device features integrated supply regulators, allowing it to be

powered from 1.2V, 1.8V, 2.5V, or 3.3V supply voltages. When

operating at 1.2V, it consumes only 230mW. Furthermore, the

power rails for the core, input, and output circuitry are electrically

independent thus may be connected to different voltage rails on the

board. This feature enables the M08045 to be DC coupled to any

upstream or downstream device regardless of its input/output

voltage level.

The 4:1 mux at the input allows any of the 4 inputs to be routed to

the integrated reclocker and its output. The device, and the input

mux, may be configured by setting the internal registers through

standard two-wire and four-wire interfaces. Optionally, the reclocker

may be configured at power-up through an external EEPROM device.

Limited configuration through hardware pin settings is also available.
