The PCF5077T is a low-voltage, low-power, burst mode power amplifier controller for GSM and PCN systems from Philips Semiconductors. It has 256 different power levels, two programmable regulator start conditions, programmable analog output voltage limitation, ramping speed based on the 13 MHz system frequency clock, and compatibility with a large number of different RF power modules.
The Philips PCF5077T is a CMOS integrated circuit designed to control the power level and up/down ramping of GSM and PCN transmit bursts. It integrates operational amplifiers, two digital-to-analog converters, and a serial bus interface to function as an integrating controller for RF power modules.
The device features a 3-wire serial bus interface compatible with power-down modes and includes an on-chip ramp generator capable of 256 different power levels. Key characteristics include a dual supply concept for analog and digital sections, programmable regulator start conditions, and a low-swing input buffer for the 13 MHz master clock.
