Integrated Device Technology Quad-Frequency Programmable XO 8N4Q001EG-1102CDI

The 8N4Q001 is a Quad-Frequency Programmable Clock Oscillator with very flexible frequency programming capabilities. The device uses IDT 's fourth generation FemtoClock® NG technology for an optimum high clock frequency and low phase noise performance. The device accepts 2.5V or 3.3V supply and is packaged in a small, lead-free (RoHS 6) 10-lead ceramic 5mm x 7mm x 1.55mm package. Besides the four default power-up frequencies set by the FSEL0 and FSEL1 pins, the 8N4Q001 can be programmed via the I2C interface to output clock frequencies between 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz to a very high degree of precision with a frequency step size of 435.9Hz ÷ N (N is the PLL output divider). Since the FSEL0 and FSEL1 pins are mapped to four independent PLL divider registers (P, MINT , MFRAC and N), reprogramming those registers to other frequencies under control of FSEL0 and FSEL1 is supported. The extended temperature range supports wireless infrastructure, telecommunication and networking end equipment requirements.
