3 Description

The DS90UB638-Q1 is a versatile deserializer

capable of receiving serialized sensor data from a

source through an FPD-Link III interface. When paired

with a DS90UB635-Q1 serializer, the DS90UB638-

Q1 receives data from imagers, supporting 2MP/

60fps and 4MP/30fps cameras, as well as satellite

RADAR and other sensors such as ToF and LIDAR.

Data is received and presented at a MIPI CSI-2

compliant output for interconnect to a downstream

processor. When configuring the CSI-2 interface for

2-lane operation, a duplicate MIPI CSI-2 clock lane

is available to provide a replicated output. Replication

mode creates two copies of the received video stream

for data logging and parallel processing.

The DS90UB638-Q1 is AEC-Q100 qualified and

designed to receive data across a 50-Ω, single-ended

coaxial. The deserializer is ideal for Power-over-Coax

applications and the receive equalizer automatically

adapts to compensate for cable loss characteristics

with no additional programming required, including

degradation over time.

Each FPD-Link III interface includes a separate

low latency bidirectional control channel (BCC)

that continuously conveys I2C, GPIO, and other

control information. GPIO signals purposed for sensor

synchronization and diagnostic features also make

use of the BCC.
