2. Circuit Description
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..

Circuit Description

- 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:

Circuit Description

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.
- IF connector
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

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
The signals in the MSM6250 enable two memories. They use two volt supply voltage, VREG_MSME and
VREG_MSMP from the PM6650. This system uses SEC's memory, KBE00F005M-F411. It is consisted of 1G
bits flash NAND memory and 512M bits SDRAM memory. It has 16 bit data line, D1[0~15] which is connected
to MSM6250.It has 22 bit address lines, A[1~22]. ROM_CS and RAM_CS signals is chip select.

2-2-5. Camera
The camera module consists of 1.3 Mega pixel. The Mega camera is a highly integrated CMOS color image
sensor implemented by Hynix CMOS sensor process realizing high sensitivity and wide dynamic range. Total
pixel array size is 1298H x 982V, and 1280H x 960V pixels are active.

2-2-6. IRDA
This system uses IRDA module, HSDL_3208, Agilent's. This has signals, "IRDA_EN"(enable signal),
"RXD0"(Input data) and "TXD0"(output data). These signals are connected to U302(MSN6250). It uses two
power signals. "VREG_MSMP" is used for circuit and "VBATT" is used for LED.

2-2-7. TransFlash Card (External Memory Card)
Memory Module has eight exposed contacts on one side. The host is connected to the module using a
dedicated eight-pin connector. Measuring just 11mm by 15mm and 1mm thick, Two-thirds the size of a SIM
module, TransFlash is even smaller than many embedded memory devices.
