SNOSCW4A –DECEMBER 2004–REVISED APRIL 2013

Bluetooth™ Radio

Check for Samples: LMX5252

FEATURES

•

The baseband interface is completely digital

and compatible with 8-pin bi-directional

BlueRF using the RXMODE2 configuration. It

can automatically adapt to the voltage levels

used by different baseband controllers,

independently of the supply voltage.

•

The LMX5252 provides a very compact radio

solution for Bluetooth™ applications that put

extra strong requirements on low cost and

small form factors. In addition, the application

benefits from very low signal loss between the

antenna and the radio.

APPLICATIONS

•

The radio completely integrates the receiver

and transmitter baluns, the antenna switch,

and filter together with the voltage-controlled

oscillator (VCO) tank on one single die. The

fractional-N delta-sigma synthesizer and the

crystal offer support for a wide range of

external reference frequency clocks or

crystals. The digital Received Signal Strength

Indicator (RSSI) allows for efficient power

control and communication with Bluetooth

Class 2 devices. Several current saving modes

are available.

•

The LMX5252 is primarily targeting cost-

sensitive consumer applications that require

fast design-in, low power consumption and

small designs. It is ideal for applications such

as:

–

2G, 2.5G, and 3G handsets

PDAs

Notebook PCs

Computer peripherals

Office network equipment

Home applications
