PRODUCT BRIEF
M08045
3G/HD/SD Serial Digital Video Reclocker
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.
