Philips Electronics 

Philips Semiconductors

Power amplifier controller for GSM and

PCN systems

Preliminary specification

PCF5077T

FEATURES

• CMOS low-voltage, low-power

• Can be used in burst mode with power-down

• 3-wire serial bus interface with the bus available in

Power-down mode

• On-chip ramp generator for 256 different power levels

with two dynamic ranges

• Two programmable regulator start conditions (VKICK

and VHOME)

• Programmable analog output voltage limitation

• Ramping speed depending on the 13 MHz system

frequency clock for Global System for Mobile

communications (GSM) and Personal Communications

Network (PCN)

• Low swing input buffer for the 13 MHz master clock

• Compatible to a large number of different RF power

modules

• Programmable temperature matching

• Dual supply concept for analog and digital part

• No external filter for suppression of clock pulse feed

through

• Direct power control with ramping function (control loop

can be switched off)

• On-chip Power-on reset for all registers

• Serial bus is compatible to bus systems independent of

additional clock pulse after rising edge of strobe signal

• Low operating current consumption

• TTL compatible interface

• Programmable gain factor for sensor signal at OP1

• Two different voltages for 1 LSB of the burst power

Digital-to-Analog Converter (DAC) are programmable.

Notes

1. The voltages VDDA1 and VDDD must be equal and VDDA2 must be either equal or greater than VDDA1 = VDDD.

2. VDDA1 = VDDD = 3 V and VDDA2 = 5 V. The VDD pins are: VDDA1, VDDA2 and VDDD.
