LMK03002 /LMK03002C Precision Clock Conditioner with Integrated VCO

Check for Samples: LMK03002

FEATURES

TARGET APPLICATIONS

•

Integrated VCO with Very Low Phase Noise

Floor

•

Data Converter Clocking

Networking, SONET/SDH, DSLAM

Wireless Infrastructure

Medical

•

Integrated Integer-N PLL with Outstanding

Normalized Phase Noise Contribution of

-224 dBc/Hz

Test and Measurement

Military / Aerospace

•

Clock Generator Performance (10 Hz - 20 MHz)

–

LMK03002C: 200 fs RMS Jitter

Jitter Cleaner Performance Grade (12 kHz to

20 MHz)

DESCRIPTION

The

LMK03002/LMK03002C

precision

clock

conditioners combine the functions of jitter

cleaning/reconditioning, multiplication, and distribution

of a reference clock. The devices integrate a Voltage

Controlled Oscillator (VCO), a high performance

Integer-N Phase Locked Loop (PLL), a partially

integrated loop filter, and four LVPECL clock output

distribution blocks.

–

LMK03002: 800 fs RMS Jitter

LMK03002C: 400 fs RMS Jitter

•

VCO Frequency: 1566 to 1724 MHz

Clock Output Frequency Range of 1 to 862

MHz

•

4 LVPECL Clock Outputs

The VCO output is optionally accessible on the Fout

port. Internally, the VCO output goes through a VCO

Divider to feed the various clock distribution blocks.

Partially Integrated Loop Filter

Dedicated Divider and Delay Blocks on Each

Clock Output

Each

clock

distribution

block

includes

•

Pin Compatible Family of Clocking Devices

3.15 to 3.45 V Operation

programmable divider,

phase synchronization

circuit, a programmable delay, a clock output mux,

and an LVPECL output buffer. This allows multiple

integer-related and phase-adjusted copies of the

reference to be distributed to four system

components.

Package: 48 Pin WQFN (7.0 x 7.0 x 0.8 mm)

The clock conditioners come in a 48-pin WQFN

package and are footprint compatible with other

clocking devices in the same family.
