VFH230C Series
Crystal Oscillators LVPECL/LVDS 3.3V
5X7 mm Surface Mount High Reliability 750 KHz to 800 MHz
These high reliability oscillators provide PECL/LVDS waveforms for applications subjected to the
most stringent environmental conditions. They are mechanically robust and weigh less than 0.2
grams. This 5X7 mm SMD package has a hermetic seal, thus ensuring the integrity of each
oscillator. Each oscillator is burned-in at 125°C for 168 hours, temperature cycled and centrifuged
then fully tested in accordance with Table 1. Reliability tests are performed per Table 2.
Features
High speed – Low jitter LVPECL or LVDS
output with tristate
Small SMD package (5X7 mm)
Stability options from +/-25ppm to +/-100ppm
Leadless chip carrier package is hermetically
sealed for superior aging and field
performance
Crystal angle controlled to +/-0.5 for excellent
temperature stability
168 hour Class B burn-in and extensive
environmental testing for best performance in
rugged field environments
Tristate option available
Serialized test data available
Calculated MTBF is 3.8X10
