M08035/M08045
SD, HD, 3G Multi-rate Reclocker
The M08035/M08045 are serial digital video reclockers with integrated trace equalization and automatic rate detect (ARD)
circuitry. The M08035 operates at data rates of 270 Mbps and 1485 Mbps, while the M08045 operates at data rates of
270 Mbps, 1485 Mbps, and 2970 Mbps.
The M08035/M08045 have 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, 27 MHz crystal, which is used as the reference
clock. It includes per lane input equalization for up to 40" of FR4 trace and two connectors in addition to output de-emphasis.
These devices feature integrated supply regulators, allowing them to be powered from 1.2 V, 1.8 V, 2.5 V, or 3.3 V supply
voltages. When operating at 1.2 V, they consume only 230 mW at 3G and HD. Furthermore, the power rails for the core, input,
and output circuitry are electrically independent and as such may be connected to different voltage rails on the board. This
feature enables the M08035/M08045 to be DC coupled to any upstream or downstream device regardless of its input/output
voltage level.
These devices may be configured by setting the internal registers though standard two-wire and four-wire interfaces. Limited
configuration is also possible through hardware pin settings.
The M08035/M08045 are offered in green and RoHS compliant, 6 mm x 6 mm, 40-pin QFN packages.
