ST3e Qz Clock Card (23413015-000-0)
Part Number: 23413015-000-0
The Stratum 3E Clock card meets or exceeds performance requirements for ANSI and Bellcore Stratum 3E and ITU and ETSI Type III Local Node clocks. The Stratum 3E Clock card reads measurement data from the Input cards, provide frequency control of the oscillators through DDS circuitry, and generates a reference signal used by the Input and Output cards. The Clock card maintains phase synchronization with the redundant Clock card. Its hardware and software also provides for temperature compensation, aging compensation for quartz oscillators, an initial offset adjustment, and frequency adjustment resolution of 1 x 10-13 or better.
