Gainesville, Ga. 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 ±0.28 ppm over a temperature range of -40° to 85°C in a surface-mount 5 x 7-mm package.
Operating at 3.3 V or 5 V, the new DFA S2 Stratum 3 TCXO offers standard frequencies of 10, 12.8, 19.44, 20.00 and 38.88 MHz. 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 <1 picosecond RMS and a holdover stability of &plus0.37 ppm over 24 hours.
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. Click here for the datasheet.
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.
