System Clock The system clock is generated on the DAC board. The clock and data signals LRCK, ADATA and BCLK from the mechanism connector SK300 are double buffered by IC300 before being delivered to the DAC. The system clock is delivered to the mech via two-position jumper PL300. Microcontroller & Display Board The system microcontroller IC100 serves the following functions: ! Control of the mechanism & decoder on the CDM14 mechanism ! Control of mute, attenuation and de-emphasis for the DAC ! Direct drive of the fluorescent display ! Remote control decoding ! Keyboard scanning ! DAC muting The keyboard scanning works by connecting the keys to a resistor ladder on an ADC input to the micro. Pressing a key presents a unique voltage to this input, which the micro is pre-programmed to interpret accordingly. The remote control data contains a Customer Code that identifies this as an Arcam product. The diode network D100 to D106 configures the micro to accept this code. Remote Bus Carrier Filter & Demodulator Remote control commands can be delivered over wire to SK500 for multi-room applications. Incoming signals are attenuated and clipped by resistors and D500. L500 and C508 form a parallel resonant circuit at approximately 37kHz. This demodulates the incoming signal and the output is passed to IC501A where it is chopped, low pass filtered and fed to IC501B to provide the RC5 output signal. Digital Output The decoder on the mechanism assembly generates an SPDIF format digital output signal. This is passed to buffer IC500A. IC500B through E are used in parallel to provide a transformer less 75-ohm source impedance to a single phono socket SK501. Optical digital output via IC502 is also tapped off the digital output signal via IC500F.
