3.2. MEMORY
3.2.1. S DRAM MEMORY INTERFACE
The MT1379 provides a glueless 16-bit interface to DRAM memory devices used as OSD, MPEG stream and video buffer
memory for a DVD player. The maximum amount of memory supported is 16 MB of Synchronous DRAM (SDRAM). The memory
interface is configurable in depth to support 128-Mb addressing. The memory interface controls access to both external SDRAM
memories, which can be the sole unified external read/write memory acting as program and data memory as well as various
decoding and display buffers.
3.3. DRIVE INTERFACES
The MT1379 supports the DV34 interface, and other RF and servo interfaces used by many types of DVD loaders. These
interfaces meet the specifications of many DVD loader manufacturers.
3.4. FRONT PANEL
The front panel is based around an Futaba VFD and a common NEC front panel controller chip, (uPD16311). The MT1379
controls the uPD16311 using several control signals, (clock, data, chip select). The infrared remote control signal is passed
directly to the MT1379 for decoding.
3.5. REAR PANEL
A typical rear panel is included in the reference design. This rear panel supports:
Six channel or two channel audio outputs
Optical and coax S/PDIF outputs.
Composite, S-Video, and SCART outputs
Optical and coax S/PDIF outputs.
Composite, S-Video, and SCART outputs
The six-video signals used to provide CVBS, S-Video, and RGB are generated by the MT1379s internal video DAC. The video
signals are buffered by external circuitry.
Six channel audio output by the MT1379 in the form of three I2S (or similar) data streams. The S/PDIF serial stream is also
generated by the MT1379 output by the rear panel. The six channel audio DACs (AK4356,PCM1606) are used for six channel
audio output with MT1379, and similarly AK4382A ,CS4392 Audio DACs are used for two channel audio output with MT1379.
