2 / 24 page 1997 Nov 19 2 Philips Semiconductors Preliminary specification Power amplifier controller for GSM and PCN systems 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. QUICK REFERENCE DATA 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. ORDERING INFORMATION SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
