CRYSTAL CONTROLLED OSCILLATORS
The Connor-Winfield
VSML62C64 is a surface mount
3.3V Voltage Controlled Crystal
Oscillator (VCXO) with
HCMOS/TTL Compatible output.
Based on a fundamental design
the VSML62C64 is designed for
phased lock loop applications
requiring low jitter and tight
stability.

PACKAGE CHARACTERISTICS
TABLE 50
Package
Hermetically sealed, ceramic pac kage with gold plated J-leads.
Note:
1)
Inclusive of frequency calibration, frequency vs. temperature stability, supply voltage change,
load change, shock and vibration, and aging for 10 years.
2) 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) Output is enabled with no connection pad 2.
