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 for the power-up default frequency
• LVCMOS/LVTTL compatible control inputs
• RMS phase jitter @ 156.25MHz (12kHz - 20MHz):
0.250ps (typical)
• RMS phase jitter @ 156.25MHz (1kHz - 40MHz):
0.290ps (typical)
• 2.5V or 3.3V supply
• -40°C to 85°C ambient operating temperature
• Available in Lead-free (RoHS 6) package
