Ultra Low Power Dual Frequency

Synthesizer for RF Personal Communications

LMX2335U

1.2 GHz/1.2 GHz

LMX2336U

2.0 GHz/1.2 GHz

General Description

The LMX2335U and LMX2336U devices are high perfor-

mance frequency synthesizers with integrated dual modulus

prescalers. The LMX2335U and LMX2336U devices are

designed for use in applications requiring two RF

phase-locked loops.

A 64/65 or a 128/129 prescale ratio can be selected for each

RF synthesizer. Using a proprietary digital phase locked loop

technique, the LMX2335U and LMX2336U devices generate

very stable, low noise control signals for the RF voltage

controlled oscillators. Both RF synthesizers include a

two-level programmable charge pump. The RF1 synthesizer

has dedicated Fastlock circuitry.

Serial data is transferred to the devices via a three wire

interface (Data, LE, Clock). Supply voltages from 2.7V to

5.5V are supported. The LMX2335U and the LMX2336U

feature very low current consumption:

LMX2335U (1.2 GHz)鈥?3.0 mA, LMX2336U (2.0 GHz)鈥?/div>

3.5 mA at 3.0V.

The LMX2335U device is available in 16-pin TSSOP, and

16-pin Chip Scale Package (CSP) surface mount plastic

packages. The LMX2336U device is available in 20-Pin

TSSOP, 24-Pin CSP, and 20-Pin UTCSP surface mount

plastic packages.
