DATASHEET  
General Description  
Features  
The IDT8N4QV01 is a Quad-Frequency Programmable VCXO with  
very flexible frequency and pull-range 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.  
Fourth generation FemtoClock® NG technology  
Programmable clock output frequency from 15.476MHz to  
866.67MHz and from 975MHz to 1,300MHz  
Four power-up default frequencies (see part number order codes),  
re-programmable by I2C  
I2C programming interface for the output clock frequency, APR  
and internal PLL control registers  
Besides the 4 default power-up frequencies set by the FSEL0 and  
FSEL1 pins, the IDT8N4QV01 can be programmed via the I2C  
interface to any output clock frequency 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 4  
independent PLL, P, 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  
Frequency programming resolution is 435.9Hz ÷N  
Absolute pull-range (APR) programmable from 4.5ppm to  
754.5ppm  
One 2.5V or 3.3V LVDS differential clock output  
Two control inputs for the power-up default frequency  
LVCMOS/LVTTL compatible control inputs  
RMS phase jitter @ 156.25MHz (12kHz - 20MHz): 0.494ps  
temperature range supports wireless infrastructure, tele-  
communication and networking end equipment requirements.
