Page 15 2.4.1 Overview The NX-5200 is a VHF Analog FM & Digital Portable transceiver designed to operate in the frequency range of 136 to 174MHz. The unit consists of a receiver, a transmitter, a phase-locked loop (PLL) frequency synthesizer, a digital control unit, and a power sup- ply circuit.
Page 16 2.4.3.3 Audio Amplifier Circuit Audio processing (high-pass filter, low-pass filter, de-emphasized and so on) at Analog FM mode and decoding at Digital mode are processed by DSP. SSI signal from DSP is converted to audio signal at IC902. The signal goes to amplifier (IC904 or IC905). While INTAMT is High, IC904 is activated and audio is heard from internal speaker.
Page 17 2.4.5 PLL Frequency Synthesizer 2.4.5.1 TCXO (X700) TCXO (X700) generates a reference frequency of 19.2MHz for the PLL frequency synthesizer. This reference signal is buffered by Q700 and IC700. And it is distributed to TX PLL (IC100), RX PLL (IC200), IF IC (IC600), GPS/Bluetooth (IC850), and IC702. The frequency adjustment is achieved by adjusting a D/A converter (IC901) output in the voltage of the control terminal of TCXO.
Page 18 2.4.6.5 Low Battery Warning The battery voltage is divided using R40 and R41 and is detected by A/D converter (IC900). When the battery voltage falls below the voltage set by the Low battery warning adjustment, the red LED blinks to notify the operator that it is time to replace the battery. If the battery voltage falls even more (approx.

Page 21 2.4.9 Bluetooth/GPS Circuit The main component of the BT/GPS circuit is BT/GPS IC (IC850). The clocks of BT/GPS IC require 19.2MHz for core and 32.768kHz slow clock (X850) for UART. 19.2MHz clock (X700) is shared with MPU/DSP (IC702), and is supplied through the clock buffer IC (IC700). The BT/GPS IC communicates to the MPU/DSP (IC702) on the HCI UART.
Page 22 2.4.9.2 GPS Circuit The RF signal is received by the antenna matched by the matching circuit. The matching circuit consists of L905, C948 and C883. And this signal applied to a high-pass filter. The filter consists of C882, C881, C880, L859 and L858. The filtered RF signal is then applied to a SAW filter (L857).
