FEATURES

DESCRIPTION

The

DS92LV0421

(serializer)

and

DS92LV0422

2

•

General

(deserializer) chipset translates a Channel Link LVDS

–

5-Channel (4 Data + 1 Clock) Channel Link

video interface (4 LVDS Data + LVDS Clock) into a

LVDS Parallel Interface Supports 24-bit

high-speed serialized interface over a single CML

Data 3-bit Control at 10 – 75 MHz

pair.

–

AC Coupled STP Interconnect up to 10

The

DS92LV0421

and

DS92LV0422

enable

Meters in Length

applications that currently use the popular Channel

–

Integrated Serial CML Terminations

Link or Channel Link style devices to seamlessly

upgrade to an embedded clock interface to reduce

–

AT–SPEED BIST Mode and Status Pin

interconnect cost or ease design challenges. The

–

Optional I2C Compatible Serial Control Bus

parallel LVDS interface also reduces FPGA I/O pins,

–

Power Down Mode Minimizes Power

board trace count and alleviates EMI issues, when

Dissipation

compared

to

traditional

single-ended

wide

bus

interfaces.

–

1.8V or 3.3V Compatible Control Pin

Interface

Programmable

transmit

de-emphasis,

receive

equalization, on-chip scrambling and DC balancing

–

>8 kV ESD (HBM) Protection

enables longer distance transmission over lossy

–

-40° to +85°C Temperature Range

cables

and

backplanes.

The

Deserializer

•

SERIALIZER – DS92LV0421

automatically locks to incoming data without an

external reference clock or special sync patterns,

–

Data Scrambler for Reduced EMI

providing easy “plug-and-go” operation.

–

DC–Balance Encoder for AC Coupling

The

DS92LV0421

and

DS92LV0422

are

–

Selectable Output VOD and Adjustable De-

programmable though an I2C interface as well as by

emphasis

pins. A built-in AT-SPEED BIST feature validates link

•

integrity and may be used for system diagnostics.

–

Random Data Lock; no Reference Clock

The DS92LV0421 and DS92LV0422 can be used

Required

interchangeably

with

the

DS92LV2421

or

–

Adjustable Input Receiver Equalization

DS92LV2422. This allows designers the flexibility to

–

EMI Minimization on Output Parallel Bus

connect to the host device and receiving devices with

different interface types, LVDS or LVCMOS.

(Spread Spectrum Clock Generation and

LVDS VOD Select)
