Product Summary

The TMS320AC01CFN is an Integrated Set-top Box Decoder. The TMS320AC01CFN is the major component of a Digital Video Broadcast (DVB) Settop Box. It incorporates: an ARM CPU and a transport packet parser (TPP) with an integrated European Common Descrambler (ECD), an MPEG-2 video decoder, an MPEG-1 audio decoder, an NTSC/ PAL video encoder, an on screen display (OSD) controller to mix graphics and video, a configurable high speed data interface, three UART serial data interfaces, programmable infra red (IR) input and output ports, a Smart Card interface, and an extension bus to connect peripherals such as: additional RS232 ports, display and control panels, and extra ROM, DRAM, or EPROM memory.

Parametrics

TMS320AC01CFN absolute maximum ratings: (1)V(IL) Max.(V)Lo Level In.Volt.=0.8; (2)V(IH) Min.(V)Hi Level In.Volt.=2.0; (3)Vsup(+) Nom.(V) Pos.Sup.Volt.=5.0; (4)Pins=120.

Features

TMS320AC01CFN features: (1)fully functional decoder using a single 16 Mbit external SDRAM; (2)accepts transport bit-streams of up to 72.8Mbps burst rate (60 Mbps average over one transport packet); (3)on-chip European Common Descrambler hardware; (4)hardware CRC accelerator for SI/PSI information processing; (5)video decoder that decodes MPEG-1 and MPEG-2 Main Profile@Main Level bit-streams; (6)audio decoder that decodes MPEG-1 Layer I and II and the basic stereo channels from MPEG-2 Multi-channel bit-streams; (7)audio output in both PCM and SPDIF formats; (8)OSD processor that enables mixture of OSD and video data with transparency; (9)BitBLT hardware that accelerates memory block move; (10)32/16 bit ARM/Thumb processor that removes the need of another CPU in the set-top box; (11)firmware that controls device operation and provides application access to hardware resources; (12)on-chip NTSC/PAL encoder that incorporates MacroVision logic for anti-taping protection; (13)analog Y/C or RGB, and Composite video outputs with 9-bit precision; (14)internally or externally generated video sync signals; (15)on-chip SDRAM controller for 16, 20, or 32 Mbit SDRAM; (16)general purpose 16-/32-bit Extension Bus Interface (EBI); (17)a configurable high speed data interface to connect to either an IEEE 1394 link device, an IEEE 1284 interface, or an external DMA device like SCSI that supports up to 16 Mbps data rate; (18)two 4-wire UART data ports supporting up to 115.2Kbps rate, and one 2-wire UART data port supporting up to 9.6Kbps rate; (19)ISO 7816-3/NDC Smart Card interface; (20)I2C master/slave interface; (21)a programmable IR input port; (22)a programmable IR output port; (23)four dedicated general purpose I/O pins and five multiplexed pins which can be configured to be general purpose I/O pins; (24)2.5 volt device with 3.3 volt I/O.
