VFH230C-CATA-800.000MHZ [CTS]
Oscillator,;
CTS 
RoHS Status
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
