Features : 

1. Single 27 MHz external clock for time base reference and internal processing; all required decoding and presentation clocks are generated internally

2. Internal system time base at 90 kHz can be synchronized via CPU port

3. Flexible memory allocation under control of the external CPU enables optimized partitioning of memory for different tasks
