  • Page 5 SHEET 1 – CPU This sheet shows the system CPU and associated circuitry. IC4 is a Cirrus EP9307 ARM CPU. The IC runs from a 1.8V core supply (VCCCORE) and a 3.3V I/O supply (VCCIO). IC2 is a 64Mbit flash memory for program and data storage. IC1 and IC3 are SDRAM memory, these run at 100MHz clock speed.
  • Page 6 SPI Bus The SPI bus connects the ARM CPU to the Sharc DSP and the PIC microcontroller on the Control board. The SPI bus is used at power up to load software into the Sharc DSP. For this, the ARM CPU is the SPI master and the Sharc DSP is the SPI slave.

  • Page 7: Serial Ports

    Serial ports The ARM CPU provides 3 serial ports, of which we make use of 2. TXD0/RXD0 are used for debugging purposes, and this serial port is accessible on the NH00 I/O board. TXD1/RXD1 are not used on the NH00 (on KA3 it is used for the iPod interface). RXD2/TXD2 are not used as a serial port;...

  • Page 8: Lcd Backlight Control

    LCD backlight control IC10 and associated components provide an adjustable voltage to drive the LCM backlight. The signal BRIGHT is a PWM signal from the ARM CPU. R67/R69/C15 scales and filters this to a DC level, which connects to the adjust pin of the voltage regulator IC10. IC10 will act so as to maintain 1.25V between its output and adjust pin, therefore the output will follow 1.25V above the adjust pin.

    NH00 I/O Board Circuit Description rev 0 PG 12 Jan 07 Introduction This board is used in the NH00 DJ audio player. It includes the audio codec, power supply and power control circuit. Block Diagram I2S Audio to CPU board Audio input 2 ch Audio output 4 ch Audio CODEC...
  • Page 10 SHEET 1 – CODEC This sheet shows the audio codec, audio input and output circuitry, muting and power supplies for the analogue section. The design features analogue inputs for a record function, though the parts for this are not fitted since the feature was removed from the product.

  • Page 11: Power Control Circuit

    SHEET 2 – POWER This sheet shows the system power supply and the power control circuit. The system is powered from a 12V DC power source; this is input on connector J8. D1 is a schottky diode that ensures the system is not damaged should the user accidentally connect a power supply with incorrect polarity.
  • Page 12 SHEET 3 – Connectors This sheet shows the connection to other boards in the system and also the fader start inputs. The CPU board plugs into 2 50 way headers J11-12. The Control board connects to J16 via a 26 way ribbon cable. The LCD display connects to J15 (data and power), and J14 (backlight).
