Precision clock generators to support multiple standards and designs

Texas Instruments has released new clock oscillator ICs with crystal input. This family called CDCM61004 family with integrated RMS jitter of 500 fs is suggested for data communications equipment.

The CDCM61004 family provide built-in voltage-controlled oscillator (VCO), which operates in frequency range 1.75 GHz to 2.05 GHz to support for the output frequency range from 43.75 MHz to 683 MHz, enabling support for multiple standards and designs. These signal generators devices consume a power of less than 500 mW.

The key specifications and features are:
Input reference including the commonly used crystal frequencies such as 24.8832 MHz, 25 MHz, and 26.5625 MHz
Input crystal bypass mode allows direct tuning on the reference
Output selectable between LVPECL, LVDS or 2-LVCMOS
Pin-compatible family allows the same hardware strapping
