The IDT8N0Q001 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 of high clock frequency and low phase noise performance. The device accepts 2.5V o r3.3V supply and is packaged in a small, lead-free (RoHS6) 10-lead ceramic 5mm x 7mm x 1.55mm package.
Besides the 4 default power-up frequencies set by the FSEL0 and FSEL1 pins, the IDT8N0Q001 can be programmed via the I2C interface to output clock frequencies between 15.476 to 260MHz to a very high degree of precision with a frequency step size of 435.9Hz÷N(N:PLLpostdivider). Since the FSEL0 and FSEL1 pins are mapped to4 independent PLL M and N divider registers (P,MINT,MFRACandN), 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.
