Service Manual 6.2 Main Board 6.2.1 Overview Baseband board consists of main chip (TX OMAP and RX OMAP), audio processing chip (CODEC) and peripheral equipment. See the following figure: Figure 6-5 Baseband Block Diagram As a highly integrated hardware platform, OMAP5912 incorporates 2 processors: ARM+DSP. The function of RX OMAP and TX OMAP is described below: RX OMAP5912 (1) ARM: Reserved.
Page 14 Service Manual 6.2.2 Power Supply Description Both PA circuit and baseband circuit are powered by the external power supply directly. The power supply circuit for the baseband board supplies power for the baseband circuit and its auxiliary modules, and provides 9.3V voltage for the exciter board and RX board. After the DC power supply is connected, the baseband board is powered up, and provides 13.6V voltage for the external development interface via OMPA control.
Page 15 Service Manual After going through the filter and protection circuit, the 13.6V power supply will power external devices via the expansion interface. The current may be up to 1A. For the 9V3A power supply, it is supplied by U821, and output by ADJ with current up to 1A. It is used to power part of the exciter, RX and baseband circuit.
Page 16 Service Manual After making response to power-up reset, OMAP5912 will output RST_OUT signal, and maintain low level for some time to reset the peripheral equipment (NOR Flash) of OMAP. For CODEC chip (U501), its resetting is subject to MPUIO6 of TX OMAP. The reset sequence of OMAP5912 is shown below: Figure 6-8 Reset Sequence 6.2.4 Clock OMAP5912 requires two clocks: system clock and 32K clock.
Page 17 Service Manual For the built-in and external clock of OMAP2912, there are two reset modes: Reset Mode0 and Reset Mode1. Reset Mode0 is adopted for this system. As for this product, system clock uses external clock, while 32K clock uses built-in clock. See the following figure: Figure 6-10 Clock Connection Block Diagram 6.2.5 Memory OMAP5912 provides two types of external memory interfaces: external memory interface slow (EMIFS)
Page 18 Service Manual AD9864 to receive demodulation signal from AD9864, and TX OMAP McBSP2 is reserved for SPI interface of RX DAC TLV5614. McBSP2 of TX OMAP is used to connect SSI interface of TX DAC TLV5614. TLV5614 works in Slave mode and is managed by DSP. McBSP3 is used to connect RX OMAP and TX OMAP for data transmission.

Service Manual 9.UHF1 (400-470MHz) Information 9.1 TX Circuit The TX circuit consists of power amplifier (PA) circuit, power control circuit, diagnosis and detection circuit and protection circuit. It is to amplify the RF signal from exciter module to 50W, which then will be output via the antenna.
Page 88 Service Manual 30dBm, which then will be sent to driver-stage PA via L-C network. 9.1.3 Driver Stage PA This PA unit is a LDM OS power tube (Q402). It can further amplify the RF signals from Q401 to 38dBm, which is then sent to final-stage PA. 9.1.4 Final-stage PA This PA unit consists of two LDMOS power tubes (Q403 and Q404).

Page 90 Service Manual 9.2.1 Front-end Circuit The HF signal from the low-pass filter passes through the electrically tunable band-pass filter controlled via TV level, to remove out-of-band interference signal and to send wanted band-pass signal to the low-noise amplifier (U402). The amplified signal goes to a band-pass filter controlled via TV level, to remove out-of-band interference signal generated during amplification, and to send wanted HF signal to the mixer.

Service Manual The 18MHz clock frequen cy is generated by the LC resonance loop. 9.3 Frequency Generation Unit (FGU) The repeater has two FGUs. One is RX FGU providing the first LO frequency for the RX system; the other is TX FGU providing carrier and exciter signal for the TX system. They work simultaneously, but are locked at different frequencies.

Service Manual 10. UHF2 (450-520MHz) Information 10.1 TX Circuit The TX circuit consists of power amplifier (P A) circuit, power control circuit, diagnosis and detection circuit and protection circuit. It is to amplify the RF signal from exciter module to 50W, which then will be output via the antenna.
Page 148 Service Manual Pre-driver Stage PA This PA unit is a LDMOS power tube (Q401). It can amplify the 13dBm RF signals from exciter unit to 30dBm, which then wil l be sent to driver-stage PA via L-C network. Driver Stage PA This PA unit is a LDMOS power tube (Q402).

Service Manual remove o ut-of-band interference signal generated during amplification, and to send wanted HF signal to the mixer. The wanted signal passes through the RF band-pass filter and low-noise amplifier and goes to the mixer (U403). Meanwhile, the first local oscillator (LO) signal generated by VCO passes through the low-pass filter and also goes to the mixer.
Page 151 Service Manual other is TX FGU providing carrier and exciter signal for the TX system. They work simultaneously, but are locked a t different frequencies. Both RX FGU and TX FGU mainly consist of a reference crystal oscillator, a PLL, a VCO and a buffer amplifier.

Service Manual 11.UHF3 (350-400MHz) Information 11.1 TX Circuit The TX circuit consists of power amplifier (P A) circuit, power control circuit, diagnosis and detection circuit and protection circuit. It is to amplify the RF signal from exciter module to 50W, which then will be output via the antenna.
Page 207 Service Manual Pre-driver Stage PA This PA unit is a LDMOS power tube (Q401). It can amplify the 13dBm RF signals from exciter unit to 30dBm, which then wil l be sent to driver-stage PA via L-C network. Driver Stage PA This PA unit is a LDMOS power tube (Q402).

The wanted signal passes through the RF band-pass filter and low-noise amplifier and goes to the mixer (U403). Meanwhile, the first local oscillator (LO) signal generated by VCO passes through the low-pass filter and also goes to the mixer.
Page 210 Service Manual other is TX FGU providing carrier and exciter signal for the TX system. They work simultaneously, but are locked a t different frequencies. Both RX FGU and TX FGU mainly consist of a reference crystal oscillator, a PLL, a VCO and a buffer amplifier.

The wanted signal passes through the RF band-pass filter and low-noise amplifier and goes to the mixer (U403). Meanwhile, the first local oscillator (LO) signal generated by VCO passes through the low-pass filter and also goes to the mixer.
