IDT's 8N3Q001 and 8N3QV001 Quad-Frequency Programmable VCXOs with very flexible frequency and pull-range programming capabilities. The devices use IDT's fourth generation FemtoClock NG technology for an optimum of high clock frequency and low phase noise performance. The devices also accept 2.5 V or 3.3 V supply and are packaged in a small, lead-free (RoHS 6) 10-lead ceramic 5 mm x 7 mm x 1.55 mm package. Besides the four default power-up frequencies set by the FSEL0 and FSEL1 pins, the IDT8N3QV01 can be programmed via the I²C interface to any output clock frequency between 15.476 MHz to 866.67 MHz and from 975 MHz to 1,300 MHz to a very high degree of precision.
