3 Description
The CDCE937-Q1 and CDCEL937-Q1 devices are
modular, phase-locked loop (PLL) based
programmable clock synthesizers. These devices
provide flexible and programmable options, such as
output clocks, input signals, and control pins, so that
the user can configure the CDCEx937-Q1 for their
own specifications.
The CDCEx937-Q1 generates up to seven output
clocks from a single input frequency to enable both
board space and cost savings. Additionally, with
multiple outputs, the clock generator can replace
multiple crystals with one clock generator. This
makes the device well-suited for head unit and
telematics applications in infotainment and camera
systems in ADAS as these platforms are evolving into
smaller and more cost effective systems.
