General Description

The LMX2335U and LMX2336U devices are high performance 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)- 3.0 mA, LMX2336U (2.0 GHz)- 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.

Features

  • Ultra Low Current Consumption
  • Upgrade and Compatible to the LMX2335L and LMX2336L devices

  • Selectable Dual Modulus Prescaler RF1: 64/65 or 128/129 RF2: 64/65 or 128/129
  • Selectable Charge Pump TRI-STATE® Mode
  • Programmable Charge Pump Current Levels RF1 and RF2: 0.95 or 3.8 mA
  • Selectable Fastlock™ Mode for the RF1 Synthesizer
  • Push-Pull Analog Lock Detect Mode
  • LMX2335U is available in 16-Pin TSSOP and 16-Pin CSP
  • LMX2336U is available in 20-Pin TSSOP, 24-Pin CSP, and 20-Pin UTCSP

Applications

  • Mobile Handsets (GSM, GPRS, W-CDMA, CDMA, PCS, AMPS, PDC, DCS)
  • Cordless Handsets (DECT, DCT)
  • Wireless Data
  • Cable TV Tuners
