IDT8N0Q001

Quad-Frequency Programmable XO IDT8N0Q001 REV H DATASHEET General Description 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 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 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: PLL post divider). Since the FSEL0 and FSEL1 pins are mapped to 4 independent PLL M and N 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. Features Fourth generation FemtoClock® NG technology Programmable clock output frequency from 15.476MHz to 260MHz Four power-up default frequencies (see part number order codes), re-programmable by I2C I2C programming interface for the output clock frequency and internal PLL control registers Frequency programming resolution is 435.9Hz ÷ N One 2.5V, 3.3V LVCMOS clock output Two control inputs ...
