2-1. SGH-ZV30 RF Circuit Description

- Antenna Switch Module (U106)

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. 6) PCS-1900 Tx, 7) PCS-1900 Rx, UMTS operation requires simultaneous reception and

transmission.

-Filter

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

- GSM Rx FILTER (F100) : For filtering the frequency band between 925 ~ 960 MHz.

- DCS Rx FILTER (F101) : For filtering the frequency band 1805 and 1880 MHz.

- PCS Rx FILTER (F102) : For filtering the frequency band 1930 and 1990 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.

- VCTCXO (OSC201)

To generate the 19.2MHz reference clock to drive the logic and RF.

- Duplexer (F204)

A duplexer splits a single operating band into receive and transmit paths.

- UMTS PAM (U202)

This is a key component in the transmitter chain and must complement the RTR6250 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.

- GSM/DCS/PCS PAM (U105)

The PAM is a key component in any transmitter chain and must complement the rest of the transmitter

precisely.For GSM, DCS, PCS 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..

- GSM/DCS/PCS l Tx VCO (OSC101)

The Tx VCO outputs for EGSM, DCS, PCS 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.

- RF VCO (OSC202)

The single-band UHF VCO is a key component within its phase-locked loop; VCO performance directly impacts

PLL and transceiver performance. UMTS Rx LO signal is generated from this VCO's output.

- 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.

- RFR6200 (U203)

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.

- RTR6250 (U104)

The RTR6250 supports multi-band, multi-mode phones with two receiver signal paths and three transmitter signal

paths:

1) Receiver paths

- EGSM-900

- DCS-1800

-PCS-1900

2) Transmitter paths

- EGSM-900 (using OPLL technique)

- DCS-1800 (using OPLL technique)

-PCS-1900

- UMTS-2100

Numerous secondary functions are integrated on-chip as well:

2-2. Baseband Circuit description of SGH-ZV30

2-2-1. PM6650

- 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 LDOs support for 1.375V, 1.8V, 2.6V,

2.85V,3.3V.IC-level interfaces include the three-line serial bus interface(SBI) used by the MSM6250 device to

control and status the PM6650 IC.

- TCXO Controller and Buffers

The PM6650 IC includes circuits for controlling the TCXO warm-up and buffering its signal for distribution

throughout the handset. Performance specifications are presented below.

2-2-2. Connector

- 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, MAIN_LCD_CSB can enable main LCD and SUB_LCD_CSB can enable small

LCD.Dimming signal enables white LED of main LCD and Dimming Control. C_Main_LCD_RESETB signal

initiates the reset process of the main LCD. C_SUB_LCD_RESETB signal initiates the Reset process of the

small LCD. 16-bit data lines(D2(0)~D(15)) transfers data and commands to LCD. Data and commands use

"C_A2(1)" 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 "VBATT and VREG_MSMP". "EAR1OP" and "EAR1ON" are used for audio

speaker. And "MOTOR_EN" from U302 enables the motor.

-Key

This is consisted of key interface pins among U302, KEY_N(0:4). These signals compose the matrix.Result of

matrix informs the key status to key interface in the U302. Power on/off key is seperated from the matrix.

The key LED use the "VBATT" supply voltage. "KEY_LED_ON" signal enables LEDs with current control.

"HALL_SW" informs the status of folder (open or closed) to the. This uses the hall effect IC, EM1681

- EMI ESD Filter

This system uses the EMI ESD filter, GMF05LC to protect noise from IF CONNECTOR part.

It is 24-pin connector. They are designed to use VBATT, CF, UART1_TX, UART1_RX, UART1_RFR,

UART1_CTS, JIG_ON, RTCK, TCK, TDI, TDO, TMS and GND. They connected to power supply

IC,microprocessor and signal processor IC.

2-2-3. Audio

EAR1OP and EAR1ON from U302 are connected to the main Receiver. MIC1P and MIC1N are connected to

the main MIC. And MIC2P and MIC2N are connected to the Earphone. YMU769 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.

Circuit Description

2-4

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, YMU769 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.

2-2-4. Memory
