Programmable FemtoClock
LVPECL Oscillator Replacement
ICS83PR226I-01
General Description
The ICS83PR226I-01 is a programmable LVPECL synthesizer that is
“forward” footprint compatible with standard 5mm x 7mm oscillators.
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 3rd generation
FemtoClock PLL technology, which delivers sub 1ps rms phase
jitter.
The ICS83PR226I-01 defaults to 125MHz using a 25MHz crystal
with all 4 of the programming pins floating (pulled HIGH with internal
pullup resistors) but can be also be set to 15 different frequency
multiplier settings to support a wide variety of applications. The
below table shows some of the more common application settings.
