VF900703 VF900703 Frequency Translator And Jitter Attenuator RoHS Status Features Two Selectable Input Frequencies Ultra Low Jitter and Phase Noise Applications Optical Networking, SONET / SDH 10 Gigabit Ethernet Broadband Access Description: The VF900703 VF900703 is a Frequency Translator and Jitter Attenuator which accepts an input frequency of 161.1328 MHz or 156.250 MHz and provides an output frequency at 156.250 MHz. The desired input is determined by the frequency select input "S0". A Lock Detect output signal indicates an "out of lock" condition. The device is implemented with a Phase Locked Loop where all Loop Filter components are integrated into the module.
