Description

General part information

CDCE937 Series

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.

Furthermore, each output can be programmed in-system for any clock frequency up to 230 MHz through the integrated, configurable PLL. The PLL also supports spread-spectrum clocking (SSC) with programmable down and center spread. This provides better electromagnetic interference (EMI) performance to enable customers to pass industry standards such as CISPR-25.
