LMK03000 Family

Precision Clock Conditioner with Integrated VCO

General Description

Features

The LMK03000 family of precision clock conditioners com-

bine the functions of jitter cleaning/reconditioning, multiplica-

tion, and distribution of a reference clock. The devices

integrate a Voltage Controlled Oscillator (VCO), a high per-

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

integrated loop filter, and up to eight outputs in various LVDS

and LVPECL combinations.

Integrated VCO with very low phase noise floor

■

Integrated Integer-N PLL with outstanding normalized

phase noise contribution of -224 dBc/Hz

VCO divider values of 2 to 8 (all divides)

Channel divider values of 1, 2 to 510 (even divides)

3 LVDS and 5 LVPECL clock outputs

Partially integrated loop filter

■

The VCO output is optionally accessible on the Fout port. In-

ternally, the VCO output goes through a VCO Divider to feed

the various clock distribution blocks.

Dedicated divider and delay blocks on each clock output

Pin compatible family of clocking devices

3.15 to 3.45 V operation

Each clock distribution block includes a programmable di-

vider, a phase synchronization circuit, a programmable delay,

a clock output mux, and an LVDS or LVPECL output buffer.

This allows multiple integer-related and phase-adjusted

copies of the reference to be distributed to eight system com-

ponents.

Package: 48 pin LLP (7.0 x 7.0 x 0.8 mm)

200 fs RMS Clock generator performance (10 Hz to 20

MHz) with a clean input clock

VCO Frequency

Range (MHz)

The clock conditioners come in a 48-pin LLP package and are

footprint compatible with other clocking devices in the same

family.
