Circuit Description
2-2. Baseband Circuit description of SGH-E750 2-2-1. PCF50603 (U405) - 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.
- Clock Generator The Clock Generator (CG) generates all clocks for internal and external usage. The 32.768 kHz crystal oscillator provides an accurate low clock frequency for the PCF50603 and other circuitry.
2-2-2. LCD Connector LCD is consisted of main MAIN LCD, SUB LCD Chip select signals in the U305, LCD_CS, can enable LCD. BACKLIGHT signal enables white LED of main LCD. These signal is from U400. 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. Key This is consisted of key interface pins KEY_ROW(0:4) and KEY_COL(0:4) in PCF5213EL1. These signals compose the matrix. Result of matrix informs the key status to key interface in the PCF5213EL1. Power on/off key is seperated from the matrix. So power on/off signal is connected with PCF50603 to enable PCF50603. Key LED is consisted of
six white
LEDs for sub key and eight white LEDs for main key. Main and Sub key LED use the
3.3V LDO for a supply voltage. KEY_LED_ON signal enables eight white LED. 2-2

Circuit Description
2-2-4. EMI ESD Filter This system uses the EMI ESD filter, U500 to protect noise from IF CONNECTOR part.
2-2-5. IF connetor It is 18-pin connector. They are designed to use VBAT, V_EXT_CHARGE, USB_D+, +VBUS, USB_D-, TXD1, RXD1, AUX_ON, EXT1, EXT2 and GND. They connected to power supply IC, microprocessor and signal processor IC.
2-2-6. Battery Charge Management A complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries. If TA connected to phone, "V_EXT_CHARGE" enable charger IC and supply current to battery. When fault condition caused, "CHG_ON" signal level change low to high and charger IC stop charging process.
2-2-7. Audio HFR_P and HFR_N from PCF5213EL1 are connected to the main speaker via analog switches. MIC_P and MIC_N are connected to the main MIC as well. YMU765 is a synthesizer LSI for mobile phones. This LSI has a built-in speaker amplifier for outputting sounds that are used by mobile phones in addition to game sounds and ringing melodies that are replayed by a synthesizer. There is Stereophonic analog output for Headphone.
2-2-8. Memory This system uses Samsung's memory, KBJ10KB00A. The KBJ10KB00A. is a Multi Chip Package Memory whichcombines 256Mbit Synchronous Burst Multi Bank NOR Flash Memory and 1Gbit NAND Flash and 128Mbit Synchronous Burst U tRAM. It has 16 bit data line, HD[1~16] which is connected to PCF5213 and MV3315DOQ, also has 24 bit address lines, HA[1~24]. There are 3 chip select signals, CS0n_FLASH, CS4n_NAND, and CS1n_RAM. In the Wrting process, WEn is fallen to low and it enables writing process to operate. During reading process, OEn is fallen to low and it enables reading process to operate. Each chip select signals in the PCF5213EL1 choose different memories.
2-2-9. PCF5213EL1 The PCF5213EL1 is mainly composed of embeded DSP and ARM core. The DSP subsystem includes the Saturn DSP core with embedded RAM and ROM, and a set of peripherals.
