Vectron International's CD-700 is a user-configured, phase-locked loop (PLL) solution designed to simplify a wide variety of clock recovery and data retiming, frequency
translation, clock smoothing and clock switching applications. The device features a phase-lock loop ASIC with a quartz stabilized VCXO for superior stability and jitter
performance. This highly integrated module provides unsurpassed performance, reliability and quality. The proprietary ASIC device includes a refined Phase Detector, a Loop
Filter Op-Amp, a Loss of Signal Alarm with Clock Return to Nominal feature, a VCXO circuit, and an optional 2n divided output.
The ASIC and quartz resonator are housed in a hermetic 16-pad ceramic leadless chip carrier. The VCXO frequency (OUT1) and division factor (OUT2) are factory set in
accordance with customer specifications. PLL response is optimized for each application by the selection of external passive components. Software is available from Vectron
to aid in loop filter component selection and loop response modeling.
