3 Description

The DS90UB635-Q1 serializer is part of TI's FPDLink

III device family designed to support high-speed

raw data sensors including 2.3MP imagers at 60-

fps and as well as 4MP, 30-fps cameras, satellite

RADAR, LIDAR, and Time-of-Flight (ToF) sensors.

The chip delivers a 4.16-Gbps forward channel and

an ultra-low latency, 50-Mbps bidirectional control

channel and supports power over a single coax

(PoC) or STP cable. The DS90UB635-Q1 features

advanced data protection and diagnostic features

to support ADAS and autonomous driving. Together

with a companion deserializer, the DS90UB635-Q1

delivers precise multi-camera sensor clock and

sensor synchronization.

The DS90UB635-Q1 is fully AEC-Q100 qualified with

a -40°C to 105°C wide temperature range. The

serializer comes in a small 5-mm × 5-mm VQFN

package for space-constrained sensor applications.
