The MT6592 introduces
the implementation of a common control interface for all analog blocks in order to communicate with the analog blocks. In addition, there are some dedicated data transfer interfaces. The common control interface translates APB bus write and read cycles to specific addresses associated with analog front end control. In the process of writing or reading these control registers, there is and transfer data to and from the analog front end. The dedicated data interface of each analog block is implemented in the corresponding digital block. The analog block includes the following functions for simulating GSM/GPRS/WCDMA baseband signal processing:
1. Baseband Rx: used for I/Q channel baseband A/D conversion
2. Baseband Tx: used for I/Q channel baseband D/A conversion and Smoothing
3. RF Control: Includes a DAC for Automatic Power Control (APC). The outputs are provided to external RF power amplifiers respectively. Also includes a DACWCDMA system for voltage bias control (Vbias), with the output provided to an external RF power amplifier.
4. Auxiliary ADC: Provides an ADC for battery and other auxiliary analog function monitoring.
5. Clock generation: a clock square waver is used to form the input sinwave clock and 10 PLLs, providing clock signals to the baseband TRX, DSP, MCU, USB, MSDC units

Block Description
BBTX includes two digital-to-analog converter channels with first-order low-pass filters. DACs are PMOS current steering
topologies with NMOS constant sink current, active RC filters to
voltage buffers

The bit width of the digital-to-analog converter is 10 bits, encoded as 7 bits for thermometer code and 7 bits for binary code in the following way.

Mixedsys hardware. The coded bits are timing synchronized by a D-type flip-flop that passes
an analog local clock. MD-PLL provides 832MHz differential clock to BBTX. Clock divider translates
DAC and AFIFO in mixing system from 832MHZ to 416MHZ

The IO power supply, dvdd18_md, is regulated to around 1.55V to supply the analog components, and
the required bias current is generated by the BBRX.
