INFORMATION

DS92LX1621 / DS92LX1622

June 1, 2010

10 - 50 MHz Channel Link III Serializer and Deserializer with

Embedded Bi-Directional Control Channel

Embedded clock with DC Balanced coding to support AC-

coupled interconnects

Capable to drive up to 10 meters shielded twisted-pair

Bi-directional control interface channel with I²C support

I²C interface for device configuration. Single-pin ID

addressing

16–bit data payload with CRC (Cyclic Redundancy Check)

for checking data integrity with programmable data

transmission error detection and interrupt control

■

General Description

The DS92LX1621/DS92LX1622 chipset offers a Channel

■

Link III interface with a high-speed forward channel and a full-

duplex control channel for data transmission over a single

differential pair. The Serializer/Deserializer pair is targeted for

direct connections between camera systems and Host Con-

troller/Frame Grabbers. The primary transport sends 16 bits

of image data over a single high-speed serial stream together

with a low latency bi-directional control channel transport that

supports I2C. Included with the 16-bit payload is a selectable

data integrity option for CRC (Cyclic Redundancy Check) or

parity bit to monitor transmission link errors. Using National’s

embedded clock technology allows transparent full-duplex

communication over a single differential pair, carrying asym-

metrical bi-directional control information without the depen-

dency of video blanking intervals. This single serial stream

simplifies transferring a wide data bus over PCB traces and

cable by eliminating the skew problems between parallel data

and clock paths. This significantly saves system cost by nar-

rowing data paths that in turn reduce cable width, connector

size and pins.

■

Up to 6 Programmable GPIO's

■

AT-SPEED BIST diagnosis feature to validate link integrity

Individual power-down controls for both SER and DES

User-selectable clock edge for parallel data on both SER

and DES

Integrated termination resistors

■

1.8V- or 3.3V-compatible parallel bus interface

Single power supply at 1.8V

IEC 61000–4–2 ESD compliant

No reference clock required on Deserializer

Programmable Receive Equalization

LOCK output reporting pin to ensure link status

EMI/EMC Mitigation

In addition, the Deserializer inputs provide equalization con-

trol to compensate for loss from the media over longer dis-

tances. Internal DC balanced encoding/decoding is used to

support AC-Coupled interconnects.

DES Programmable Spread Spectrum (SSCG)

outputs
