Universal Clock - High Frequency

LVPECL Clock Synthesizer

FEATURES

General Description

• XR81102-CA02: Factory configured

The XR81101-CA02 is a clock synthesizer operating at a 3.3V/2.5V supply

with Integer divider, using a 25MHz parallel resonant crystal reference input

provides a 125MHz LVPECL outputs. The device is optimized for use with a

25MHz crystal (or system clock) and generates a 125MHz output clock for

GE applications. The LVPECL outputs have very low phase noise jitter of

sub 150fs, while consuming extremely low power.

• One differential LVPECL output pair

• Crystal oscillator interface which can also be

overdriven using a single-ended reference clock

• Output frequency: 125MHz

• Crystal/input frequency: 25MHz, parallel resonant

crystal

The application diagram below shows a typical synthesizer configuration

with any standard crystal oscillating in fundamental mode. Internal load

capacitors are optionally available to minimize/eliminate external crystal

loads. A system clock can also be used to overdrive the oscillator for a syn-

chronous timing system.

• RMS phase jitter @ 125MHz, 1.875MHz - 20MHz:

< 150fs

• Full 3.3V or 2.5V operating supply

• -40°C to 85°C ambient operating temperature

• Lead-free (RoHS 6) package

The typical phase noise plot below shows the jitter integrated over the

1.875MHz to 20MHz range that is widely used in WAN systems. These

clock devices show a very good high frequency noise floor below -150dB.

APPLICATIONS

• Gigabit Ethernet

• Low-jitter Clock Generation

• Synchronized clock systems

The XR81102 is a family of Universal Clock synthesizer devices in TSSOP-

8 packages. The devices generate ANY frequency in the range of 100MHz

to 1.5GHz by utilizing a highly flexible delta sigma modulator and a wide

ranging VCO. These devices can be used with standard crystals or external

system clock to support a wide variety of applications. This family of prod-

ucts has an extremely low power PLL block with core power consumption

40% less than the equivalent devices from competition. By second sourcing

several of the existing sockets, these devices provides a very compelling

power efficiency value benefit across all market segments.
