DESCRIPTION

The DS92LX1621 / DS92LX1622 chipset offers a

Channel Link III interface with a high-speed forward

channel and a full-duplex back channel for data

transmission over a single differential pair. The

Serializer/Deserializer pair is targeted for direct

connections between automotive camera systems and Host Controller/Electronic Control Unit (ECU).

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 TI’s embedded clock

technology allows transparent full-duplex

communication over a single differential pair, carrying

asymmetrical bi-directional control information without

the dependency 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

narrowing data paths that in turn reduce PCB layers,

cable width, and connector size and pins.

In addition, the Deserializer inputs provide

equalization control to compensate for loss from the media over longer distances. Internal DC balanced

encoding/decoding is used to support AC-Coupled

interconnects.

The sleep function provides a power-savings mode

and a remote wake up interrupt for signaling of a

remote device.

The Serializer is offered in a 32-pin WQFN package,

and Deserializer is offered in a 40-pin WQFN

package.
