Circuit Description

2-2. Baseband Circuit description of SGH-E360 2-2-1. PCF50603 (U400) -

Power Management Eight low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal system performance and long battery life. A programmable boost converter provides support for 1.8V, 3.0V SIMs, while a self-resetting, electronically fused switch supplies power to external accessories. Ancillary support functions, such as RTC module and High Voltage Charge pump, Clock generator, aid in reducing both board area and system complexity. I2C BUS serial interface provides access to control and configuration registers. This interface gives a microprocessor full control of the PCF50603 and enables system designers to maximize both standby and talk times. Supervisory functions. including a reset generator, an input voltage monitor, and a temperature sensor, support reliable system design. These functions work together to ensure proper system behavior during start-up or in the event of a fault condition(low microprocessor voltage, insufficient battery energy, or excessive die temperature).

-

Backlight Brightness Modulator The Backlight Brightness Modulator (BBM) contains a programmable Pulse-width modulator (PWM) and FET to modulate the intensity of a series of LED’ s or to control a DC/DC converter that drives LCD backlight. This phone (SGH-E360) use PWM control to contrast the backlight brightness.

BACKLIGHT signal enables white LED of main LCD. These signal is from U200. 16-bit data lines(LD(0)~LD(15)) transfers data and commands to LCD. Data and commands use "RS" signal. If this signal is high, Inputs to LCD are commands. If it is low, Inputs to LCD are data. The signal which informs the input or output state to LCD, is required. But this system is not necessary this signal. So "L_WR" signal is used to write data or commands to LCD. Power signals for LCD are "VDD_IO_HIGH".

2-2-3. BLUE TOOTH This system uses Blue Tooth module, LBMA46LCB2, Murata. This has signals, "BT_INT"(Interrupt signal), "RXD2"(input data) and "TXD2"(output data), PCM control signal(DCL[PCMCLK], DO[PCM_IN], DU[PCM_OUT], FSC[PCM_SYNC]) These signals are connected to PCF5213EL1EL1.
