HPOUTL and HPOUTR, with common volume control for L and R, is suitable for direct headphone drive. FUNCTIONAL DESCRIPTION The IC is intended for use within the audio FM system of VHS video recorders. Three modes of operation can be distinguished: • Record mode • Playback mode DCOUTL and DCOUTR are intended for VU meter drive. It is connected to the selected stereo audio input after the volume control block. The output signal at DCOUTL and DCOUTR is proportional to the square root of the recorded audio signal (see Fig.3). • Loop-through mode. Switching and control of the three modes is done by the I2C-bus. Record mode Playback mode The audio signal, selected from the four stereo audio inputs (EXT1L, EXT1R, EXT2L, EXT2R, CINL, CINR, TUNL and TUNR), is fed to the volume control stage (separate for left [L] and right [R]). The information for LINOUT is, after summing of L and R, derived from either one of the four stereo inputs or the volume control output or one of the mono inputs (EXN1 and EXN2). After the Low-Pass Filter (LPF) and signal compression in the noise reduction (NR) and filter block the audio signal is available at AFOUTL and AFOUTR. The compressed signal is now FM modulated on a RF carrier in the PLL block. After low-pass filtering and summation of both RF carriers (L and R) the signal is available at FMOUT. The two FM modulated RF carriers, present at the two FMINL and FMINR inputs after being band-pass filtered, are demodulated in the PLL block. The LF audio signal is fed through a sample-and-hold circuit to suppress head-switching noise. The demodulated audio signal is available at AFOUTL and AFOUTR. The audio signal is low-pass filtered and expanded in the noise reduction (NR) and filter block. The resulting audio signal is available after the output and headphone select blocks for all four output stages (LINEL, LINER, MODOUT, HPOUTL, HPOUTR, DCOUTL and DCOUTR). The functionality of the output and headphone select blocks is identical to the record mode. During playback DCOUTL and DCOUTR are connected to the headphone select block. The output select block offers the possibility to choose eight different audio signal modes: 3. Right. The functionality of the input and normal select blocks is also identical to record mode (see Fig.3), which offers the possibility to control (other) audio signals independently for LINOUT (see Fig.4). 4. Mono. Loop-through mode 1. Stereo. 2. Left. 5. Normal. This mode is similar to the record mode (see Fig.3), except for the FMOUT pin, which is inactive, and the RAF output which is active LOW (see Fig.5). 6. Mixed stereo (stereo + LININ). 7. Mixed left (left + LININ). 8. Mixed right (right + LININ). These audio signal modes are selectable for the output stages LINEL, LINER and MODOUT. The standard audio output is LINEL and LINER, e.g. for SCART output. MODOUT is a mono audio output, with an overload-protecting AGC, to drive an external RF modulator. 1995 Mar 21 7 Philips Semiconductors Product specification Audio FM processor for VHS hi-fi audio AFINL/R FMINL/R FMOUT EXT2L/R EXT1L/R CINL/R TUNL/R EXN1 EXN2 56 AFOUTL/R 1,50 61,55 TDA9610H 2,49 NR AND FILTER PLL 27,28 OUTPUT SELECT LINEL/R 30 3,4 MODOUT 5,6 7,8 INPUT SELECT HEADPHONE SELECT VOLUME CONTROL 9,10 VOLUME CONTROL 22,23 HPOUTL/R 31,32 DCOUTL/R NORMAL SELECT 48 52 TDA9610H 47 33 MKA359 - 1 LINOUT LININ Fig.3 Record mode.

The RAF bit can be overruled externally by applying a low-ohmic voltage to the RAF I/O (pin 14) either logic 0 or logic 1 (0 or +5 V). The actual mode of the IC is determined by the level measured at this pin. 2. The two record modes are equal, only differing in their reaction to forcing RAF LOW at the RAF I/O pin; the status of the IPAF bit determines whether the IC is switched to the playback or loop-through mode.

Bit PAFM has the same effect as the internally generated mute signal from the modem part when no FM carrier is detected during playback mode. If one (or both) of these signals is HIGH, the audio signal coming from the modem is muted.

The bits SAOL, SAOR and SAON provide eight output select functions, left and right are the left and right hi-fi channels, normal is the conventional audio channel, linear audio input (LININ; pin 33). Table 10 Bit HSF; note 1 HSF MODE 0 − 1 headphone select Table 11 Bit NSS; note 1 DESCRIPTION NSS MODE headphone output signals identical to line outputs LINEL and LINER [por] 0 − headphone output signals independently selectable 1 normal special select DESCRIPTION signal at LINOUT is the mono version of selected stereo line input pair [por] special output signals selectable for LINOUT Note Note 1. Normally the headphone outputs carry the same audio signal as present at the line outputs (LINEL and LINER), so the signal is selectable by means of the bits SAOL, SAOR and SAON. However when bit HSF is set HIGH, the headphone output has its own output select function switchable with bits HSL and HSR to stereo, left, right and normal (see Section “Function byte”). 1. Normally the bits NSH and NSL select one of the four possible stereo line inputs (TUNL/R, CINL/R, EXT1L/R, EXT2L/R) as the source signal for linear out. Left and right channels of the selected input are added to give a mono signal as output. 1995 Mar 21 When bit NSS is set HIGH, four special input selects can be made in combination with the same bits NSH and NSL; volume controlled, tuner left (TUNL), EXN1 and EXN2 (see Section “Input byte”). 12 Philips Semiconductors Product specification Audio FM processor for VHS hi-fi audio TDA9610H Input byte Table 12 Bits of input byte BIT DESCRIPTION ISH Input Select HIGH; see Table 13 ISL Input Select LOW; see Table 13 NSH Normal Select HIGH; see Table 14 NSL Normal Select LOW; see Table 14 Table 13 Bits ISH and ISL; note 1 ISH ISL MODE DESCRIPTION 0 0 Tuner TUNL and TUNR selected (as hi-fi stereo input source) [por] 0 1 Cinch CINL and CINR selected 1 0 Ext1 EXT1L and EXT1R (e.g. Scart input) selected 1 1 Ext2 EXT2L and EXT2R selected Note 1. With bits ISH and ISL the stereo input signal is selected which is fed to the hi-fi processing. One out of four stereo sources can be selected. The terms: Tuner, Cinch, Ext1 and Ext2 are used for describing purposes only, technically all four inputs are equal (except for the fact that tuner left (TUNL, pin 6) is also selectable by Normal Select). Table 14 Bits NSH, NSL and NSS; note 1 NSH NSL NSS(2) 0 0 0 Tuner TUNL and TUNR selected (as normal audio input source) [por] 0 1 0 Cinch CINL and CINR selected 1 0 0 Ext1 EXT1L and EXT1R selected 1 1 0 Ext2 EXT2L and EXT2R selected 0 0 1 Volume hi-fi input source selected; taken after record volume control 0 1 1 Exn1 additional mono input (EXN1, pin 48) selected 1 0 1 Tuner left only TUNL selected (e.g. dual language) 1 1 1 Exn2 additional mono input (EXN2, pin 52) selected MODE DESCRIPTION Notes 1. With bits NSH and NSL in combination with bit NSS the input signal is selected which is fed out at pin 47 (LINOUT). With bit NSS set LOW a selection can be made between the four stereo line inputs (like the hi-fi input select). With bit NSS set HIGH, bits NSH and NSL make a selection between four special select functions. When a stereo input source is selected, both channels are added to obtain a mono output signal, then the output ( L + R) signal at LINOUT is equal to: -------------------2 ( L × Volume Left + R × Volume Right ) In the Volume mode the output signal is equal to: ----------------------------------------------------------------------------------------------------2 Note that for the Volume mode the hi-fi input select (ISH and ISL) determines the used input source. 2.

Normally (bit HSF set LOW) the headphone outputs carry the same audio signal as present at the line outputs (LINEL and LINER), so the signal is selectable by means of the bits SAOL, SAOR and SAON. However, when bit HSF is set HIGH the headphone output has its own output select function switchable with bits HSL and HSR. a) These special headphone selections are also active for the VU meter drive during playback. 2.

To lower the dissipation in a stand-by situation, the 12 V supply voltage at pin 19 (VDDA1) and pin 20 (VDDH) may be switched off, with pins 19 and 20 ‘floating’. No low-ohmic DC path to ground may be seen from pins 19 and 20, because this will drain extra current from the 5 V supply via these pins to ground. Measure the frequency at FMOUT (pin 56) with a frequency counter and use the VCO TEST modes (see Section “Function byte”) to output only the channel of interest. Because of the fact that the I2C circuitry and the digital outputs RAF, NTSC and XS are supplied via the 5 V supply, no I2C settings will be lost and the output pins can still be used. Adjust the VCO frequencies to 1.4 MHz ±10 kHz and 1.8 MHz ±10 kHz by means of the potentiometers at pin 64 (FADJL) and pin 53 (FADJR). When NTSC is to be the main video standard, set NTSC on and adjust to 1.3 MHz and 1.7 MHz for optimum frequency accuracy. For instance, XS can be used to drive external mute transistors to mute the DC jump at the line outputs when switching the 12 V supply. Standard FM deviation and audio level RAF I/O Reference levels of frequency deviation and audio output level are set by the resistor value at pin 24 (RVAR); simultaneous for left, right, playback and record. Typical resistor values can be calculated with equation: R typ The status of the I2C RAF bit is output at pin 14 (RAF = HIGH; record). This output can be used to switch the audio FM head amplifier to playback and record. If accurate fast switching of the TDA9610H is needed, this pin can also be used as input. Thereby overruling the I2C RAF bit. To make this possible the RAF output is current limited. ∆f 2 ---------------- 50 kHz- = ---------------------------------------------- × 2.2 kΩ A ------------------------------------- 400 mV (RMS)- When using the RAF pin as output, no more than 35 µA (LOW) and 185 µA (HIGH) current may be drawn from this pin to assure the mode of the TDA9610H is not changed. Where: ∆f = reference FM deviation. A = reference audio output level (1 kHz audio frequency). When using the RAF pin as input, the voltage source used must be capable of delivering at least 345 µA (forced HIGH; >3.5 V) or sinking at least 65 µA (forced LOW; <1.5 V). If adjustment for overall tolerance is needed, R has to be made adjustable for the range 0.7Rtyp to 1.4Rtyp. Set the TDA9610H in playback. Use a HF test generator to make a carrier of 1.4 MHz with the desired modulation and input this signal at FMINL (pin 61) or before the band-pass filter and measure the audio output level at LINEL (pin 27). 1995 Mar 21 38 Philips Semiconductors Product specification Audio FM processor for VHS hi-fi audio TDA9610H PACKAGE OUTLINE QFP64: plastic quad flat package; 64 leads (lead length 1.95 mm); body 14 x 20 x 2.8 mm SOT319-2 c y X 51 A 33 52 32 ZE Q e E HE A A2 (A 3) A1 θ wM pin 1 index Lp bp L 20 64 detail X 19 1 ZD w M bp e v M A D B HD v M B 0 5 10 mm scale DIMENSIONS (mm are the original dimensions) UNIT A max.

Plastic quad flat-packs Several techniques exist for reflowing; for example, thermal conduction by heated belt, infrared, and vapour-phase reflow. Dwell times vary between 50 and 300 s according to method. Typical reflow temperatures range from 215 to 250 °C. BY WAVE During placement and before soldering, the component must be fixed with a droplet of adhesive. After curing the adhesive, the component can be soldered. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 min at 45 °C. Maximum permissible solder temperature is 260 °C, and maximum duration of package immersion in solder bath is 10 s, if allowed to cool to less than 150 °C within 6 s. Typical dwell time is 4 s at 250 °C. REPAIRING SOLDERED JOINTS (BY HAND-HELD SOLDERING IRON OR PULSE-HEATED SOLDER TOOL) Fix the component by first soldering two, diagonally opposite, end pins. Apply the heating tool to the flat part of the pin only. Contact time must be limited to 10 s at up to 300 °C. When using proper tools, all other pins can be soldered in one operation within 2 to 5 s at between 270 and 320 °C. (Pulse-heated soldering is not recommended for SO packages.) A modified wave soldering technique is recommended using two solder waves (dual-wave), in which a turbulent wave with high upward pressure is followed by a smooth laminar wave. Using a mildly-activated flux eliminates the need for removal of corrosive residues in most applications. For pulse-heated solder tool (resistance) soldering of VSO packages, solder is applied to the substrate by dipping or by an extra thick tin/lead plating before package placement. BY SOLDER PASTE REFLOW Reflow soldering requires the solder paste (a suspension of fine solder particles, flux and binding agent) to be 1995 Mar 21 TDA9610H 40 Philips Semiconductors Product specification Audio FM processor for VHS hi-fi audio TDA9610H DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
