Bluetooth Adapter IC

PCF26100

FEATURES

The PCF26100 performs the following functions:

• Power-on reset (reset)

• System clock generation for baseband controller

• Reference clock generation for the UAA3558

• Low-power clock generation for baseband controller

• Transmit clock generation for baseband controller

(1 MHz)

• Serial interface conversion between JTAG and 3-wire

S-bus

• Timing control generation for the UAA3558

• Transmit data conversion from digital-to-analog

gaussian shaped

• RSSI conversion from analog-to-digital and access

through serial JTAG interface

• Transmit PA control information from JTAG interface

digital-to-analog conversion

• Provides radio ID through the serial JTAG interface

• System clock oscillator trimming.

GENERAL DESCRIPTION

The PCF26100 is a mixed signal based adapter device for

wireless Bluetooth systems. The device adapts the

baseband interface of the Philips UAA3558 radio to the

Philips PCF26002 and PCF26003 baseband controller

devices and also to the BlueRF JTAG Unidirectional

RxMode 2.

The adapter is provided as a low risk solution to a working

Bluetooth system based on existing components. The

adapter ASIC implementation incorporates, as much as

possible, features to come to a complete Bluetooth

system, meeting the Bluetooth RF requirements.

From the Bluetooth system point of view the PCF26100 is

a transparent adaptation device between the baseband

controller and the UAA3558 radio.
