DS92LV042x 10-MHz to-75 MHz Channel Link II Serializer and Deserializer

With LVDS Parallel Interface

1 Features

3 Description

The DS92LV042x chipset translates a Channel Link

LVDS video interface (4 LVDS Data + LVDS Clock)

into a high-speed serialized interface over a single

CML pair. The DS92LV042x enables applications

currently using popular Channel Link or OpenLDI

LVDS style devices to upgrade seamlessly to an

embedded clock interface. This serial bus scheme

reduces interconnect cost and eases design

challenges. The parallel OpenLDI LVDS interface

also reduces FPGA I/O pins, board trace count, and

alleviates EMI issues when compared to traditional

single-ended wide bus interfaces.

Emphasis

The DS92LV042x chipset is programmable through

an I²C interface as well as through pins. A built-in, at-

speed BIST feature validates link integrity and may

be used for system diagnostics. The DS92LV0421

and DS92LV0422 can be used interchangeably with

the DS92LV2421 or DS92LV2422. This allows

designers the flexibility to connect to the host device

and receiving devices with different interface types:

LVDS or LVCMOS.
