BCM87C751 is a powerful, flexible and lowcost Digital Controlled Monitor System, basedon the 87C751 microcontroller. It employs I2Cbus control with various I2C bus controlledperipherals (PCF8582EP-EEPROM andTDA8444 D/A converter). The controlfunction is implemented via 8 6-bit DCvoltage output from TDA8444.Some features of the system:• Flexible approach, especially for multisyncor auto sync operation• Mode detection and frequencymeasurements by microprocessor• Mode switching under software control• Elimination of potentiometers• Quick factory alignment (DACs can bepreset)• Automatic factory alignment possible
