CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield
VSHD824C1 is a surface
mount 5.0V Voltage
Controlled Crystal Oscillator
(VCXO) with an HCMOS
output. Based on a
fundamental design the
VSHD824C1 is designed for
phased lock loop applications
requiring low jitter and tight
stability.

PACKAGE CHARACTERISTICS
TABLE 5.0
Package
Non-hermetic package consisting of an FR4 substrat e with grounded metal
cover.
PROCESS RECOMMENDATIONS
TABLE 6.0
Solder Reflow
The component solder used internal to this device has a m elting point of
221
C. The peak temperature inside the device should be less than or
equal to 220
C for a maximum of 10 seconds
Wash
Ultrasonic cleaning is not recommended.
Notes
1.0
Nominal frequency tolerance after reflow soldering, Vc=2.5V, @ 25
C.
2.0
Referenced to Fo @ 25C. Positive Slope.
3.0
Inclusive of calibration, frequency vs. temperature stabi lity, supply voltage change, load change, shock and vibration and
aging over 15 years, Vc=2.5 Vdc.
4.0
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.
