2. SGH-Z107 Circuit Description

1. SGH-Z107 RF Circuit Description

1. Antenna Switch Module (U100)
The antenna switch module allows multiple operating bands and modes to share the same antenna. A common
antenna connects to one of five paths: 1) UMTS-2100 Rx/Tx, 2) EGSM-900 Rx, 3) EGSM-900 Tx, 4) DCS-1800
Rx, and 5) DCS-1800 Tx. UMTS operation requires simultaneous reception and transmission.

2. Filter
To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band.

- GSM Rx FILTER (F101)→For filtering the frequency band between 925 ~ 960 MHz.

- DCS Rx FILTER (F100)→For filtering the frequency band 1805 and 1880 MHz.

- WCDMA Rx FILTER (F201)→For filtering the frequency band 2110 and 2170 MHz.

- WCDMA Tx FILTER (F202)→For filtering the frequency band 1920 and 1980 MHz.

3. TCVCXO (OSC202)
To generate the 19.2MHz reference clock to drive the logic and RF.

4. Duplexer (F203)
A duplexer splits a single operating band into receive and transmit paths.

5. Isolator (MIS201)
An isolator between the Power Amplifier and the duplexer is highly recommended to provide constant load and
source impedances (respectively) to those devices.

6. UMTS PAM (U202)
This is a key component in the transmitter chain and must complement the RTR6200 IC precisely; jointly they
dominate the UMTS transmitter performance characteristics. Parameters such as gain, output power level, ACLR,
harmonics, Rx-band noise, and power supply current are critical.

7. GSM/DCS PAM (U102)
The PAM is a key component in any transmitter chain and must complement the rest of the transmitter precisely.
For GSM and DCS operation, the closed-loop transmit power control functions add even more requirements
relative to the UMTS PA. In addition to gain control and switching requirements, the usual RF parameters such
as gain, output power level, several output spectrum requirements, and power supply current are critical.

8. GSM/DCS Dual Tx VCO (OSC101)
The dual Tx VCO outputs, one for EGSM and one for DCS, drive a resistive network that splits the active signal
into two signals: 1) the input to the active PAM – this is the low loss path, and 2) the OPLL feedback signal.

9. Dual VCO (OSC201)
The dual-band UHF VCO is a key component within its phase-locked loop; VCO performance directly impacts
PLL and transceiver performance. GSM/DCS Rx/Tx LO & UMTS Rx LO signal is generated from this dual VCO's
output.

Circuit Description

10. RFL6200 (U201)
The RFL6200 includes an LNA circuit optimized for UMTS-2100 operation. The LNA is separated from all other
receive functions contained within the RFR6200 receiver IC to improve mixer LO to RF isolation – a critical
parameter in the Zero-IF architecture.

11. RFR6200 (U205)
The RFR6200 provides the Zero-IF receiver signal path, from RF to analog baseband, for UMTS-2100
applications. The RFR6200 accepts its UMTS input signal from the handset RF front-end design. The UMTS input
is configured differentially to optimize second-order inter-modulation and common mode rejection performance, and
implements MSM-controlled gain adjustments to extend the receiver dynamic range.

12. RTR6200 (U101)
The RTR6200 supports multi-band, multi-mode phones with two receiver signal paths and three transmitter signal
paths:

1) Receiver paths

- EGSM-900

- DCS-1800

2) Transmitter paths

- EGSM-900 (using OPLL technique)

- DCS-1800 (using OPLL technique)

- UMTS-2100
Numerous secondary functions are integrated on-chip as well:

3) Phase-locked loop circuits

- PLL#1 and an on-chip VCO supports UMTS Tx

- PLL#2 and an external VCO supports EGSM Rx and Tx, DCS Rx and Tx, and UMTS Rx

4) Transceiver LO generation and distribution circuits

- EGSM-900 Rx and Tx

- DCS-1800 Rx and Tx

- UMTS-2100 Tx

1.1. Power Management
Ten low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal
system performance and long battery life. It provides seven LDO support for 2.6V, 2.8V while a self-resetting,
electronically fused switch supplies power to external accessories. Ancillary support functions, such as RTC
module and RTC charger, Clock Buffer, aid in reducing both board area and system complexity.
SBI BUS serial interface provides access to control and configuration registers. This interface gives full control of
the MSM6200 and enables system designers to maximize both standby and talk times.
Supervisory functions. including a reset generator, an input voltage monitor, and a ADC Conertte 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).

1.2. Keypad Backlight

The Keypad backlight driver output is at pin 17 (KEYBD_DRV) and is designed to drive parallel connected LEDs
directly. Its output current level is SBI-programmable and meets the performance specified below.
Input parameters are not specified since they are internal.

1.3. TCXO Controller and Buffers

The PM6050 IC includes circuits for controlling the TCXO warm-up and buffering its signal for distribution
throughout the handset. Performance specifications are presented below.

2. Connector

2-1. LCD Connector
LCD is consisted of main LCD(color 262K TFT LCD) and small LCD(OLED color 65K LCD). Chip select signals
in the U302, LCD_CS1- can enable small LCD. W_LED_ON signal enables white LED of main LCD, EN_EN
signal enables EL of small LCD.
"RESET-, TFT_RESET_N" signal initiates the Reset process of the LCD.
8-bit data lines(AD(0)~AD(7)) transfers data and commands to Small LCD through by pass capacitor. 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.
Power signals for LCD are "VDD_LP" and "2.8LV". "SPK+" and "SPK-" from U533 are used for audio speaker.
And "Vibrator" from Q702 enables the motor.

matrix. So power on/off signal is connected with U302 to enable U601. twelve key LED use the "VBAT" supply
voltage. "KEY_LED" signal enables LEDs with current control. "HALL_SW" informs the status of folder (open or
closed) to the. This uses the hall effect IC, A3210ELH. A magnet under main LCD enables A3210ELH.

the Hands free kit. MIC_P and MIC_N are connected to the main MIC. And EAR_MIC1P and EAR_MIC1N are
connected to the Earphone.
YMU765 has a built-in amplifier, and thus, is an ideal device for outputting sounds that are used by mobile
phones in addition to game sounds and ringing melodies that are replayed by a synthesizer.
The synthesizer section adopts "stereophonic hybrid synthesizer system" that are given advantages of both FM
synthesizers and Wave Table synthesizers to allow simultaneous generation of up to 32 FM voices and 32 Wave
Table voices. Furthermore, YMU765 has a built-in hardware sequencer that helps to realize complex play without
heavily loading the host CPU. And this device also has a built-in circuit for controlling vibrators and LEDs
synchronizing with play of music. The consumed electric current can be stopped to the minimum by power down
mode when not operating.
The hardware sequence built in this device allows playing of the complex music without giving excessive load to
the CPU of the portable telephones. Moreover, the registers of the FM synthesizer can be operated directly for
real time sound generation, allowing, for example, utilization of various sound effects when using the game
software installed in the portable telephone.

4. Memory
The signals in the MSM6200 enable two memories. They use only one volt supply voltage, VDD_LP from the
PM6050. This system uses AMD's memory, AM50DL128BG. It is consisted of 128M bits flash NOR memory and
32M bits SRAM memory. It has 16 bit data line, AD[0~15] which is connected to MSM6200. It has 22 bit
address lines, A[1~22]. ROM_CS and RAM_CS signals is chip select.

NAND Flash memory and the other is 128Mbit SDRAM memory. Multi-media processor doesn't have a NAND
memory interface. But we make a software algorithm use for NAND memory.
