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 (V
KICK
and V
HOME
)
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.
