New Series 632 SMT Clock Oscillators

CTS and Digi-Key Introduce a New Series of HCMOS/TTL Clock Oscillators

The new 3.2mm x 2.5mm clock oscillator product family, designated by model 632, provides a small mechanical solution for applications with tight real-estate constraints while requiring high performance timing or signal to noise figure. Such applications may include but not limited to: Personal Optical Network (PON), USB (IEEE 1394), or IF L.O. (local oscillator within radio transceiver). CTS’s 632 series offers a miniature mechanical package solution while maintaining low jitter performance over wide frequency along with +/-50PPM frequency stability over commercial or industrial temperature ranges. In addition, it supports low operating voltages of 1.8VDC, 2.5VDC 2.8VDC, and 3.3VDC CTS 632 Clock Oscillators
