Surface-Mount TCXOs Promise High Stability

The D53G series of temperature-compensated crystal oscillators (TCXOs) from Connor-Winfield are miniature sources that provide clipped sine-wave output signals. Available with frequencies of 20 to 26 MHz, the RoHS-compliant oscillators are supplied in surface-mount housings measuring 5.0 x 3.2 mm. They feature frequency stability of +/-0.5 PPM and frequency tolerance of +/-4.6 PPM over the -30 to +85C temperature range. The TCXOs, which suffer less than 1 ps jitter and operate from a +3.3-VDC supply, are ideal for use in Stratum 3 applications, GPS receivers, and instrumentation.
