VF Technologies, a division of ValpeyFisher Corporation, has introduced the latest addition to its current offering of high-performance quartz crystal oscillators; the Stratum 3E Clock.

In order to meet Bellcore's requirements per pp.3.1. and 5.2, the Stratum 3E Clock must be able to deliver less than 10 ppb total frequency change in holdover mode for a period of 24 hours. This is broken out into ± 4 ppb over operating temperature range (– 40 to 80 ° C MAX), and ± 0.5 ppb aging over 24 hours. Other features of the new Stratum 3E Clock include a warm-up time of less than two minutes, power consumption of less than .05 W at 25°C, HCMOS/TTL compatible output (sinewave optional), and a 5V (12V optional) supply voltage.
