INTEGRATED CIRCUITS DATA SHEET TDA10045H DVB-T channel receiver Product specification Supersedes data of 2000 Jun 21 File under Integrated Circuits, IC02 2001 Nov 08 Philips Semiconductors Product specification DVB-T channel receiver TDA10045H FEATURES • 2 and 8 kbytes Coded Orthogonal Frequency Division Multiplexer (COFDM) demodulator (fully DVB-T compliant: ETSI 300-744) • All modes supported, including hierarchical modes • Fully automatic transmission parameters detection (including Fast Fourier Transformer (FFT) size and guard interval) GENERAL DESCRIPTION The TDA10045H is a single-chip channel receiver for 2 and 8 kbytes COFDM modulated signals based on the ETSI specification (ETSI 300-744). The device interfaces directly to an IF signal, which could be either 1st or 2nd IF and integrates a 10-bit Analog-to-Digital Converter (ADC), a Numerically Controlled Oscillator (NCO) and a Phase-Locked Loop (PLL), simplifying external logic requirements and limiting system costs. • Digital Signal Processor (DSP) based synchronization (software can be upgraded on the fly) • No extra-host software required • On-chip 10-bit Analog-to-Digital Converter (ADC) • 2nd or 1st IF variable analog input • Only fundamental crystal oscillator required (4 MHz typical ±100 ppm) The TDA10045H performs all the COFDM demodulation tasks from IF signal to the MPEG-2 transport stream. An internal DSP core manages the synchronization and the control of the demodulation process, and implements specially developed software for robustness against co-channel and adjacent channel interference, to deal with Single Frequency Network (SFN) echo situations, and to assist in a very fast scan of the bandwidth. After baseband conversion and FFT demodulation, the channel frequency response is estimated, which is based on the scattered pilots, and filtered in both time and frequency domains. This estimation is used as a correction on the signal, carrier by carrier. A common phase error and estimator is used to deal with the tuner phase noise. The Forward Error Correction (FEC) decoder is automatically synchronized by the frame synchronization algorithm that uses the TPS information included in the modulation. An embedded ‘pulse killer’ algorithm enables the bad effects of short and strong impulsive noise interference that could be caused by electrical domestic devices and/or car traffic to be greatly reduced. • 6, 7 and 8 MHz channels with the same crystal • Pulse killer algorithm to protect against impulse noise • Digital frequency correction (±90 kHz) • Frequency offset (±1/6 MHz) automatic estimator to speed-up the scan • RF tuner input power measurement • Parallel or serial transport stream interface • BER measurement (before and after Viterbi decoder) • Signal-to noise ratio estimation • Constellation, CSI and channel frequency response outputs • TPS bits I2C-bus readable (including spare ones) • Controllable dedicated I2C-bus for the tuner (5 V tolerant) • 3 low frequency spare DACs and 2 spare inputs • CMOS 0.2 µm technology. This device is controlled via an I2C-bus (master). The chip provides 2 switchable I2C-buses derived from the master: a tuner I2C-bus to be disconnected from the I2C-bus master when not necessary and an EEPROM I2C-bus. The DSP software code can be fed to the chip via the master I2C-bus or via the dedicated EEPROM I2C-bus. APPLICATIONS • DVB-T fully compatible • Digital data transmission using COFDM modulation. Designed in 0.2 µm CMOS technology and housed in a 100 pin QFP package, the TDA10045H operates over the commercial temperature range. 2001 Nov 08 2 Philips Semiconductors Product specification DVB-T channel receiver TDA10045H ORDERING INFORMATION TYPE NUMBER TDA10045H 2001 Nov 08 PACKAGE VERSION NAME QFP100 DESCRIPTION plastic quad flat package; 100 leads (lead length 1.95 mm); body 14 × 20 × 2.8 mm 3 SOT317-2 This text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here in _white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here inThis text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader. white to force landscape pages to be ...

IF interface • It is either an analog IF amplifier when IF1 is sampled (direct IF: digital downconversion concept) or an analog IF amplifier followed by a downconversion from IF1 to IF2 at a few MHz (e.g. 4.57 MHz) • When this second solution is used, the ADC sampling clock could be used (after low-pass filtering) as a reference clock for downconversion (twice the ADC sampling clock could also be provided) • The IF amplifier is controlled by the digital AGC of the chip. A simple RC circuit filters the single bit (∆Σ modulated) AGC control (VAGC) • The sampling clock could also be used to control an external ADC, the inputs to the chip will then be digital (FI[9:0]). 2001 Nov 08 13 Philips Semiconductors Product specification DVB-T channel receiver TDA10045H PACKAGE OUTLINE QFP100: plastic quad flat package; 100 leads (lead length 1.95 mm); body 14 x 20 x 2.8 mm SOT317-2 c y X 80 A 51 81 50 ZE e E HE A A2 (A 3) A1 θ wM pin 1 index Lp bp L 31 100 detail X 30 1 wM bp e ZD v M A D B HD v M B 0 5 10 mm scale DIMENSIONS (mm are the original dimensions) UNIT A max.

SOLDERING Introduction to soldering surface mount packages 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). • For packages with leads on two sides and a pitch (e): – 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; There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. – smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. 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, convection or convection/infrared 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 220 °C for thick/large packages, and below 235 °C for small/thin packages. Manual soldering 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: 2001 Nov 08 15 Philips Semiconductors Product specification DVB-T channel receiver TDA10045H Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE WAVE BGA, HBGA, LFBGA, SQFP, TFBGA not suitable suitable(2) HBCC, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, SMS not PLCC(3), SO, SOJ suitable LQFP, QFP, TQFP SSOP, TSSOP, VSO REFLOW(1) 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.
