PRODUCT SUMMARY

CX72303: 1.8 V Ultra-Low Power Bluetooth™ RF Transceiver

APPLICATIONS

DESCRIPTION

The CX72303 is the lowest powered, fully integrated single-

chip Bluetooth™ radio transceiver. Fully compliant with

Bluetooth Specification v1.1, the CX72303 was designed from

the ground up for extreme low power operation in handsets,

headsets, or other power sensitive applications. Extreme low

power 1.8 V operation is combined with high performance to

exceed the Bluetooth requirements for Class 2 and 3 operation.

• ISM 2.4 GHz frequency band

• Personal wireless connectivity

• Cellular phones, handsets, headsets, and earpieces

• PDAs and palm-top computers

• PC and laptop computers

FEATURES

The CX72303 has an internal voltage regulator that allows

operation with higher supply voltages while holding the line on

power consumption. An extended frequency range is provided

to allow operation in all 2.4 GHz Industrial, Scientific, and

Medical (ISM) band regulatory jurisdictions. Transmitter output

power is up to +3 dBm with a typical receiver sensitivity of

–82 dBm at the antenna.

• Fully integrated single-chip transceiver with on-chip VCO,

synthesizer, PA, LNA, image-reject downconverter, IF filters,

RSSI, and demodulator for the ISM 2.4 GHz band

• Class 2 and 3 Bluetooth v1.1 compliant

• –82 dBm typical Rx sensitivity at antenna

• Low voltage supply (1.8 V)

Fabricated in a Silicon-Germanium (SiGe) Bi-polar

Complementary Metal Oxide Semiconductor (BiCMOS) process,

the CX72303 is a state-of-the-art mixed signal device mounted

in a small, low profile 7 x 7 x 0.8 mm Bump Chip Carrier

(BCC++) 48-pin package.

• Internal dual mode 1.5 V/1.8 V regulator available on

CX72303-61 option; CX72303-11 option offers 1.5 V

regulator only

• 19 mA peak Tx current at maximum power

• 24 mA peak Rx current consumption

• 11 mA peak Tx current at –10 dBm

• 15 µA low power timing clock mode

A block diagram of the CX72303 is shown in Figure 1.

• <1 µA power-down current consumption

• –40 to +85 °C Bluetooth-compliant temperature range

• –70 to +125 °C functional temperature range

• Digital crystal frequency error compensation up to 36 ppm

• Programmable Tx power control over 30 dB range with 2 dB

steps

• High efficiency direct modulation transmitter using ∆Σ

fractional-N synthesizer

• Low phase noise and closed loop PLL transmitter

• Integrated PLL-based FSK digital demodulator. No external

component required

• Fast dynamic threshold FSK bit slicer

• High reliability, high yield SiGe BiCMOS process with low

multiplicative 1/f noise

• Programmable 120 to 180 µs synthesizer settling time

• Available in a 48-pin BCC++ package
