13mhz Mad2 Nokia 5110

System Module Technical Documentation

- CODER (Block encoding/decoding and A51&A52 ciphering)

- AccIF(Accessory Interface)

- SCU (Synthesizer Control Unit for controlling 2 separate synthesizer)

- UIF (Keyboard interface, serial control interface for COBBA PCM Codec, LCD Driver and CCONT)

- SIMI (SimCard interface with enhanched features)

- PUP (Parallel IO, USART and PWM control unit for vibra and buzzer)

The MAD2 operates from a 13 MHz system clock, which is generated from the 13Mhz VCXO frequency. The MAD2 supplies a 6,5MHz or a 13MHz internal clock for the MCU and system logic blocks and a 13MHz clock for the DSP, where it is multiplied to 52 MHz DSP clock. The system clock can be stopped for a system sleep mode by disabling the VCXO supply power from the CCONt regulator output. The CCONT provides a 32kHz sleep clock for internal use and to the MAD2, which is used for the sleep mode timing. The sleep clock is active when there is a battery voltage available i.e. always when the battery is connected.
