  • Page 19 2.4.1 Overview The NX-5600HB is a Low Band Analog FM & Digital Mobile transceiver designed to operate in the frequency range of 39 to 50MHz. The unit consists of a receiver, a transmitter, a phase-locked loop (PLL) frequency synthesizer, a digital control unit, and a power supply circuit.
  • Page 20 2.4.4 Transmitter System 2.4.4.1 Audio Band Circuit Refer to the “LEVEL DIAGRAM” in this manual. The signal from microphone is amplified and converted to digital signal by CODEC (IC902). IC902 includes AGC function. Digital signal is transferred to MPU/DSP (IC706) through SSI. 2.4.4.2 Baseband Circuit Refer to the "LEVEL DIAGRAM"...
  • Page 21 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 IC703. And it is distributed to PLL (IC100), IF IC (IC600), and MPU/DSP (IC706). The frequency adjustment is achieved by adjusting a D/A converter (IC715) output in the voltage of the control terminal of TCXO.
  • Page 22 2.4.6.3 Interface Circuit The Interface unit is connected by a flexible cable (CN7 of the Main unit, CN1 of the Interface unit). Up to 2 control heads can be connected to the Interface unit. The control head is used for control and display of the radio equipment. 2.4.6.4 The DSP circuit consists of a MPU/DSP (IC706) and processes the base band signal.
