The stream data is first applied to an on-chip descrambler incorporating a DVB descrambling algorithm, on the basis of 14 control word pairs stored in on-chip RAM. Demultiplexing is subsequently applied to the stream, to separate up to 32 individual data streams. – 4 TS/PES filters for retrieval for data at TS or PES level for applications such as subtitling, TXT or retrieval of private data The demultiplexer section includes clock recovery and timebase management. Program Specific Information (PSI), Service Information (SI), Conditional Access (CA) messages and private data are selected and stored in external memory, for subsequent off-line processing by the internal PR3930 CPU core. – Flexible DMA based storage of the 32 section substreams and 4 TS/PES data substreams in the external memory • System time base management with a double counter mechanism for clock control and discontinuity handling, 2 Presentation Time Stamp (PTS)/Decoding Time Stamp (DTS) timers To support advanced board testing facilities the SAA7219 includes boundary scan test hardware, according to the EJTAG standard. The device features a Low-power sleep mode, which is capable of sustaining set-top box stand-by functionality, thus eliminating the need for a separate front-panel controller. The SAA7219 requires a supply voltage of 3.3 V and most devices input and output interfaces are 5 V tolerant except the extension bus which is 3.3 V only. The SAA7219 is mounted in a SQFP208 package. • A GP/HS filter which can serve as an alternate input from for example IEEE 1394 devices. The IEEE 1394 GP/HS mode supports packet insertion and has an internal SRAM for storing 2 packets. It can also output either scrambled or descrambled TS to IEEE 1394 devices. 2 GENERAL DESCRIPTION 2.1 SAA7219 overview 2.2 The device is part of a comprehensive source decoding kit which contains all the hardware and software required to receive and decode MPEG-2 transport streams, including descrambling, demultiplexing. In addition, it includes a PR3930 core which is a 32-bit MIPS RISC-based CPU core supporting the MIPS 16 instruction set to reduce memory requirements and several peripheral interfaces such as UARTs, I2C-bus units, an IEC 1883, and an IEEE 1284 (Centronics) interface. The SAA7219 is therefore capable of performing all controller tasks in digital television receiver applications such as set-top boxes. Furthermore, the SAA7219 is compliant to DVB and MULTI2 standards. 3 SAA7219 in a DVB system The SAA7219 has been designed to offer optimum performance when used with the SAA7215 for MPEG-2e AVG decoding. • Synchronous bus interface transfer at 40.5 MHz on 16 bits • SAA7215 has one dedicated SDRAM for MPEG-2e audio video handling and one for graphics and CPU data. The second memory offers high bandwidth and low latency to the SAA7219 when accessing it to download graphics or executing some applications. This enables a high level of performance together with a low system cost by having one SDRAM for graphics and CPU data.

SOLDERING Introduction to soldering surface mount packages • For packages with leads on two sides and a pitch (e): This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “Data Handbook IC26; Integrated Circuit Packages” (document order number 9398 652 90011). – larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; – smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. 8.2 The footprint must incorporate solder thieves at the downstream end. • For packages with leads on four sides, the footprint must be placed at a 45° angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical dwell time is 4 seconds at 250 °C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Typical reflow peak temperatures range from 215 to 250 °C. The top-surface temperature of the packages should preferable be kept below 230 °C. 8.3 8.4 Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C. Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: 1999 Sep 20 Manual soldering 16 Philips Semiconductors Preliminary specification MPEG2 Transport RISC processor 8.5 SAA7219 Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE REFLOW(1) WAVE BGA, LFBGA, SQFP, TFBGA not suitable suitable(2) HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, SMS not PLCC(3), SO, SOJ suitable LQFP, QFP, TQFP SSOP, TSSOP, VSO suitable suitable suitable not recommended(3)(4) suitable not recommended(5) suitable Notes 1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”. 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 1999 Sep 20 17 Philips Semiconductors Preliminary specification MPEG2 Transport RISC processor 9 SAA7219 DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
