DATA SHEET
General Description
The IDT8N3D085 is a LVPECL Dual Frequency-Programmable
Crystal 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) 6-lead ceramic 5mm x 7mm
x 1.55mm package.
The device can be programmed to any frequency in the range from
15.476MHz to 866.67MHz and from 975MHz to 1,300 MHz and
supports a very high degree of frequency precision of 218Hz or
better. One of two pre-set output frequencies is selected by the
FSEL pin.The extended temperature range supports wireless
infrastructure, telecommunication and networking end equipment
requirements.
