Overview
The CDCM61001RHBR/2801, produced by Texas Instruments, is a high-performance, low phase noise, fully-integrated voltage-controlled oscillator (VCO) clock synthesizer. This component is designed to generate low-jitter clock outputs from a low-frequency crystal or LVCMOS input, making it highly versatile for various wireline and data communication applications. The device features a single universal output buffer that can be configured to operate in different output modes, including LVPECL, LVDS, and LVCMOS. It is packaged in a 32-pin VQFN (Very Thin Quad Flat No-Lead) exposed pad, which is RoHS compliant and suitable for surface mount applications.
