Quad-Frequency Programmable XO

The 8N0Q001 is a quad-frequency programmable clock oscillator with very flexible frequency programming capabilities. The device uses Renesas' 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 four default power-up frequencies set by the FSEL0 and FSEL1 pins, the 8N0Q001 can be programmed via the I2C interface to output clock frequencies between 15.476MHz and 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 four 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.
