Universal Clock - High Frequency

LVCMOS Clock Synthesizer

FEATURES

General Description

• XR81101-AA02: Factory configured

The XR81101-AA02 is a clock synthesizer operating at a 3.3V/2.5V sup-

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

input provides a 125MHz LVCMOS output. The device is optimized for

use with a 25MHz crystal (or system clock) and generates a 125MHz out-

put clock for GE applications. The LVCMOS output has very low phase

noise jitter of sub 150fs, while consuming extremely low power.

• One LVCMOS output

• 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

synchronous 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 XR81101 is a family of Universal Clock synthesizer devices in

TSSOP-8 packages. The devices generate ANY frequency in the range of

10MHz to 200MHz 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 products has an extremely low power PLL block with core power con-

sumption 40% less than the equivalent devices from competition. By sec-

ond sourcing several of the existing sockets, these devices provides a

very compelling power efficiency value benefit across all market seg-

ments.
