ES4428 General Description

The ES4428/ES4427 Web/DVD Internet set-top box chipset seamlessly combines both Web browser technology and DVD technology into a highly integrated, low-cost solution for the next
generation of Internet set-top boxes for home use.

The ES4428, which is based on ESS's Programmable Multimedia Processor (PMP) device architecture, includes a programmable internal RISC processor core that makes it adaptable for use in embedded systems applications such as set-top boxes. The ES4427 companion chip supplies proper video sync capabilities and performs NTSC- and PAL-based video encoding and decoding as necessary to provide broadcast quality video to the television screen.

The ES4428 DVD processor integrates MPEG-based audio and video data stream decoding for DVD/VCD/SuperVCD playback, DVD system navigation and Dolby AC-3 decoding into a single
device. The ES4428 demuxes the incoming DVD audio and video data streams from the DVD loader using its glueless 8/16-bit parallel interface, which is hardware-compatible with many
DVD loaders. The ES4428 also supports both 8- and 16-bit Flash/Read-Only Memory (ROM) and 8- and 16-bit Synchronous DRAM (SDRAM) memory I/O operations.

The ES4428 controls data I/O transactions to and from the ES4427 companion chip through its 8-bit Device Serial Connect (DSC) parallel bus interface. The ES4428 also provides a 16-bit
wide hardware interface with V.90-compatible modem subsystems incorporated into the set-top box design. The ES4427 incorporates a multi-standard TV encoder that supports both the NTSC and PAL formats and CCIR-601 non-square operations. Two microphone ADCs and PLL clock synthesizers are incorporated in the ES4427 device architecture.

The ES4427 includes an I/O-mapped auxiliary expansion port that interfaces with the ES4428. Four pins of the port can be configured as edge-triggered interrupts, supporting critical
functions, such as handling remote control and modem interrupt requests, DVD/VCD loader resets and modem board resets. Command and register accesses are issued through the
DSC interface from the ES4428 DVD processor to the ES4427 through the device serial communication (DSC) interface for accessing the internal registers of the ES4427. The DSC interface port is comprised of three interface signals, the strobe (DSC_S), data (DSC_D), and clock (DSC_C).

The DSC port is selected when the DSC strobe goes high and latches the data at the rising edge of the clock. Each 16-bit DSC transfer is comprised of an address followed by data.

The ES4428 is available in an industry-standard 208-pin Plastic Quad Flat Pack (PQFP) package, while the ES4427 is available in an industry-standard 100-pin PQFP package.
