DESCRIPTION

· The 8N0QV01 is a Quad-Frequency Programmable VCXO with flexible frequency and pull-range programming capabilities.

· Utilizes IDT’s Fourth Generation FemtoClock®NG technology for high clock frequency and low phase noise performance.

· Operates with a 2.5V or 3.3V supply in a 10-lead ceramic package measuring 5mm x 7mm x 1.55mm.

· Supports output clock frequencies from 15.476MHz to 260MHz with a precision frequency step size of 435.9Hz÷N.

· Features four default power-up frequencies set by FSEL0 and FSEL1 pins, with reprogramming capability via I2C interface.
