VECTRON 6798

Product Data Sheet
Z5 Series
P/N’s 6797 & 6798
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: 1.0“x 1.15”x 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 6797 & 6798 have been optimized to work with
the Semtech Chip ACS8510 SETS to meet the
requirements of Bell Core specification GR-1244CORE and ITU G.813.
Both units have 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.

Note: TCXO’
s are precision subsystems with tolerances measured to ±0.01 ppm. 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.
