TCXO touts tight stability, small size

Fordahl USA Inc. said it has introduced the industry's smallest wide temperature range Stratum III and Sonet temperature compensated crystal oscillator (TCXO). The new lead-free/RoHS compliant TCXO offers a temperature stability of ±0.28ppm over a temperature range of -40Z°C to 85°C in a surface-mount 5-by-7mm package.

Operating at 3.3V or 5V, the new DFA S2 Stratum 3 TCXO offers standard frequencies of 10-, 12.8-, 19.44-, 20- and 38.88MHz. Other frequencies may be specified. The TCXO will maintain an overall ±4.6 ppm frequency tolerance over 15 years. Other key specifications include low jitter of

The DFA S2-LHZ provides a LVHCMOS/HCMOS output and a tri-state function. This oscillator is designed particularly for Stratum III or Sonet (SMC) applications as specified in Telcordia GR-1244 CORE, GR-253 CORE and ITU-T G.813 option 1 and 2.

Available in tape-and-reel packaging, the DFA S2 device is priced at $20 in quantities of 5,000. Delivery is eight to ten weeks.
