1.2 MEMORY

1.2.1 SDR AM Memory Interface

The MT1389E 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 110-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.

RIVE INTERFACES

The MT1389E supports the DV34 interfac e, and other RF and servo interfaces used by
many types of DVD loaders. These interfaces meet the specifications of many DVD loader
manufacturers.

1.4 FRONT PANEL

The front panel is based around an Futaba VFD and a common NEC front panel
controller chip, (PTC16311). The MT1389E c ontrols the PTC16311 using several c ontrol signals,
(clock, data, chip select). The infrared remote c ont rol signal is passed directly to the MT1389E for
decoding.

1.5 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, and SCART outputs
The four-video signals used to provide CVBS, and RGB are generated by the MT1389E’s internal

video DAC. The video signals are buffered by external circuitry.

S (or similar) data streams. The
S/PDIF serial stream is also generated by the MT1389E output by the rear panel. The six channel
audio DACs (AK4356,CS4360, PCM1606) are used for six channel audio output with MT1389E.
