Overview

The CDCM7005 is a high-performance, low phase noise and low skew clock synchronizer that synchronizes an on-board voltage controlled crystal oscillator (VC(X)O) frequency to an external reference clock. The device operates up to 2 GHz. The PLL loop bandwidth and damping factor can be adjusted to meet different system requirements by selecting the external VC(X)O, loop filter components, frequency for PFD, and charge pump current. Each of the five differential LVPECL and five LVCMOS pair outputs can be programmed by a serial peripheral interface (SPI). The SPI allows individual control of the frequency and enable/disable state of each output. As the system requires external components like a loop filter and VC(X)O, this EVM provides an easy method to evaluate and modify the performance and parameters of the clock system in conjunction with the specific customer application. Loop bandwidth can be selected as low as 10 Hz or less, allowing the device to clean the system's clock jitter. In non PLL mode, the CDCM7005 can be used as a simple LVPECL or LVCMOS buffer with divider options.

Note: This EVM contains Pb, a necessary component for QML parts
