VFH2321-VFH2324
VFH2421-VFH2424
XO Hi-REL, 1.8V
5x7mm SMD, HCMOS
Features
Leadless chip carrier package is hermetically
sealed for superior aging and field performance
Crystal angle controlled to ±0.5 minute for
excellent temperature stability
168 hour Class B burn-in and extensive
environmental testing for best performance in
rugged field environments
RoHS Status
Guarantee start-up with a ramping DC supply
Start-up time <5ms, typical
Tristate option available
Calculated MTBF is 3.8x106 hours at 125°C
Description
These high reliability oscillators provide HCMOS clock 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. The calculated MTBF is 3.8x106 at 125°C.
