Product Data Sheet Z5 Series P/N 6825 Temperature Compensated Crystal Oscillators Features 12.800 MHz output frequency Low Current Draw Consumption: <20 mA Aging to <4.0 ppm for 20 years Package: 1.0x 1.15x 0.395(25.40x29.21x10.03mm) LS TTL output +3.3 Vdc (operable over +3.135 Vdc to +5.5 Vdc) For use with Semtech Chip ACS8510 SETS SONET/SDH Network Timing Sources Computer Telephony CT-BUS The 6825 has been optimized to work with the S e m t e c h Ch ip ACS 8 5 1 0 S E T S t o m e e t t h e requirements of Bell Core specification GR-1244CORE and ITU G.813. This unit has been designed to meet the Frequency vs Supply requirement of ±0.05 ppm over any ±5% change in Supply from a minimum of +3.135 Vdc to a maximum of +5.5 Vdc. Note: Other Stability and Output Options are available.

Non-Hermetically sealed TCXO s should not be subjected to a wash process that will immerse the TCXO in solvents. NO CLEAN is the recommended procedure. The Z5 series of TCXO s has been designed for pick and place reflow soldering. The suggested reflow profile is shown above. The TCXO may be reflowed two times. Typical frequency shift as a result of reflow is <1.0 ppm per reflow. VI recommends waiting at least two hours after reflow before measuring the unit. 6825 (±0.28 ppm -5ºC to +55ºC) USA: Vectron International 267 Lowell Road, Hudson, NH 03051 . . . . .Tel: 1-88-VECTRON-1 Fax: 1-888-FAX-VECTRON EUROPE: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
