CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield
VSHD54D1EG is a surface
mount 5.0V Voltage
Controlled Crystal Oscillator
(VCXO) with an HCMOS/TTL
Compatible Tri-State output.
Based on a fundamental
design the VSHD54D1EG is
designed for phased lock loop
applications requiring low
jitter and tight frequency
stability.

Notes
1.0
Inclusive of calibration, frequency vs. temperature stability, supply voltage change, load change, shock and
vibration, 15 years aging.
2.0
Absolute pull range (APR) is the minimum guaranteed pull range of the VCXO under all conditions over lifetime
operation. The APR is referenced to Fo. Positive Slope.
3.0
Output is enabled with no connection on pin 2.
4.0
Output is in high impedance state when output is disabled.
