Description QAMI5107 1 Description The QAMI5107 provides an integrated demodulator/decoder solution for digital cable receivers for compressed video, sound and data services. A QAM (quadrature amplitude modulation) demodulator and FEC performs IF to MPEG-2 block processing of QAM carriers. The demodulated stream is then processed by video and audio decoders. The device implements a fully unified SDR SDRAM based memory architecture that integrates the Omega2 video decoder cell together with a blitter engine and a multichannel DMA controller to provide enhanced performance for graphics and real-time stream transfers. Transfer of data such as pixmaps, audio streams, stills and PES can be performed efficiently using the QAMI5107 DMA. A true-color mode provides OSD graphics allowing the display of RGB16 formats: RGB565, ARGB1555 and ARGB4444. This directly supports up to 65,536 colors in a region. Alpha blending by region or by pixel is available for mixing with video and background layers. The above feature set, guarantees a smooth user interface and high performance for demanding middlewares such as MHPTM. The QAMI5107 is the first single chip cable STB IC to combine a very low cost solution with advanced security features. DVB and ICAM descramblers together with a smart card interface ensure that all the major conditional access systems can be supported. 1.1 QAM Demodulator features Decodes ITU-T J.83-Annexes A/C and DVB-C bit streams Processes Japanese transport stream multiplex frame (TSMF) High-performance integrated A/D converter suitable for direct IF architecture in all QAM (quadrature amplitude modulation) modes Supports 16, 32, 64, 128 and 256 point constellations Very low power consumption Full digital demodulation Variable symbol rates Front derotator for better low symbol rate performance and relaxed tuner constraints Integrated matched filtering Robust integrated adaptive pre and post equalizer On-chip FEC A/C with ability to bypass individual blocks 10 programmable GPIO Two AGC outputs suitable for delayed AGC applications (sigma-delta outputs) Integrated signal quality monitors, plus lock indicator and interrupt function mapped to GPIO pin Improved signal acquisition System clock generated on-chip from quartz crystal Low frequency crystal operations 4, 16, 25 - 30 MHz 4 IC addresses Easy control and monitoring via 2-wire fast I2C bus 2/6 QAMI5107 Description Additional I2C bus (I2C repeater) dedicated to tuner control for minimum tuner disturbance Programmable clock derived from system clock and available for external use Parallel and serial output interfaces, with DVB common interface support On chip voltage regulator CMOS technology, 1.0 V operation 1.2 Decoder features Enhanced ST20 32-bit VL-RISC CPU - 200-MHz, single cycle cache, 4-Kbyte instruction cache, 4-Kbyte data cache, 2-Kbyte SRAM Unified memory interface - - - - Up to 166 MHz,16-bit wide SDRAM interface and 133 MHz DDR interface 4 separately configurable banks, 8/16-bits wide SRAM, peripheral, flash, SFlashTM support Support for low cost DVB-CI single transport stream input support for DVB transport streams integrated DVB, ICAM descramblers Fully programmable horizontal and vertical SRCs 3 display planes 8 bpp CLUT graphics, 256 x 30 bits (AYCbCr) CLUT entries, 16 bpp true color graphics, RGB565, ARGB1555, ARGB4444 formats.

It provides a single chip solution for the following functions: QAM demodulation, FEC, transport, descrambling, MPEG a/v decoding, CPU, graphics and peripherals. Few external components are required to realize a complete STB solution resulting in very low BOM cost. The QAMI5107 is perfectly suited for digital conversion of existing analog networks as well as providing advanced security enhancements and system cost down for designs currently using the QAMi5516 and STx5105/STx5107.
