Programmable FemtoClock NG LVPECL
Oscillator Replacement
ICS83PN625I
General Description
The ICS83PN625I is a programmable LVPECL synthesizer that is
“forward” footprint compatible with standard 5mm x 7mm oscillators.
The device uses IDT’s fourth generation FemtoClock NG
technology for an optimum of high clock frequency and low phase
noise performance. Forward footprint compatibility means that a
board designed to accommodate the crystal oscillator interface and
the optional control pins is also fully compatible with a canned
oscillator footprint - the canned oscillator will drop onto the
10-VFQFN footprint for second sourcing purposes. This capability
provides designers with programability and lead time advantages of
silicon/crystal based solutions while maintaining compatibility with
industry standard 5mm x 7mm oscillator footprints for ease of supply
chain management. Oscillator-level performance is maintained with
IDT’s 4th Generation FemtoClock NG PLL technology, which
delivers sub 0.5ps rms phase jitter.
The ICS83PN625I defaults to 312.5MHz using a 25MHz crystal with
2 programming pins floating (pulled down/pulled up with internal
pullup or pulldown resistors) but can also be set to 4 different
frequency multiplier settings to support a wide variety of
applications. The below table shows some of the more common
application settings.
