If no inserted black level is available on the input signal it is recommended to select the black insert mode of the input clamp. FUNCTIONAL DESCRIPTION The TDA9176 is a Luminance Transient Improvement (LTI) IC which is suitable for operation in both 50 and 100 Hz environments. The IC also contains chrominance delay lines to compensate for the luminance delay. A diagram of the LTI processor is illustrated in Fig.3. The chrominance delay lines compensate for the delay of the luminance signal in the LTI circuit. This is to safeguard a correct colour fit. The LTI processor contains a delay line which drives a minimum/maximum (MINMAX) detector and a control circuit. When the control circuit discovers a transient, the LTI shaper switches from the minimum to the maximum signal (or vice-versa, depending on the sign of the transient). By mixing the original signal with the switched signal, a variable transient improvement is obtained. The 50% crossing point of the transient is not affected by the LTI circuit. Two and three level sandcastles can be used as a timing signal, only the clamp pulse of the sandcastle input is used in the device. If the rise time improvement is active, the duty cycle of the output signal can be varied with the line width control input. This function delays the rising edge and advances the falling edge (or vice-versa). This can be used for example aperture correction. Figures 4 and 5 illustrate some waveforms of the LTI processor. 3. Black insertion or clamping of the luminance signal. There are three selection inputs to select the modes of operation. These selections are as follows: 1. 1FH or 2FH, for the 50 or 100 Hz applications. 2. Amplitude selection, for optimum operation of the circuit with 450 mV (p-p) or 1 Vbl-wh luminance signals. The selection inputs must be directly connected to either ground or the supply rail. The modes are selected as follows: Frequency selection: GND = 1FH mode, VCC = 2FH mode For correct operation the LTI circuit requires a number of fast clamps. To overcome problems where noise is superimposed on the input signal the device contains an input clamp that can either clamp to the black level of the input signal, or, insert a black level. When a black level is inserted, the internal clamps do not respond to the noise on the input signal (see Fig.1). When the input signal already has an inserted black level (e.g. when it is driven from the TDA9170 picture booster) it is recommended to Amplitude selection: GND = 450 mV (p-p), VCC = 1 Vbl-wh mode Black insertion/clamp: GND = clamp mode, VCC = black insert mode. If the selection pins are left floating, internal 1 MΩ resistors connected to the pins set the device to, 1FH mode, black insert mode and 1 Vbl-wh mode.

All data given is for a 3.0 kΩ external resistor connected to the PTAT current source (pin 16). 2. The test input is a step whose rising edge is the rising half of a sine wave. For the 1FH mode the input rise time is 250 ns (i.e. half of a 2 MHz sine wave). For the 2FH mode the input rise time is 125 ns (i.e. half of a 4 MHz sine wave). The output rise time is measured between the 10% and 90% points of the output signal. 3. The figures given on duty cycle variation refer to the following conditions: the device should be in 1FH mode (pin 1 at ground level) and the rise time should be at minimum (pin 3 connected to Vref, pin 10). 4. In the transparent mode, i.e. at normal rise time, the bandwidth of the luminance path for which the group delay time constant is 7 MHz in the 1FH mode and 14 MHz in the 2FH mode. However, as the circuit uses all-pass filters, ringing on the output signal may occur if the bandwidth of the input signal is larger than 7 MHz in the 1FH mode or 14 MHz in the 2FH mode. As the LTI processor adds harmonics to the luminance signal, the bandwidth of the output signal is much larger than 14 MHz. 5. The maximum DC load on the reference voltage pin (pin 10) should not exceed 1 mA. 1996 Jan 30 10 Philips Semiconductors Preliminary specification Luminance Transient Improvement (LTI) IC TDA9176 TEST AND APPLICATION INFORMATION YOUT UOUT VOUT handbook, full pagewidth 100 nF 100 nF 100 nF 8V 100 nF 100 µF 0V 100 nF 3.0 kΩ 16 15 14 13 12 11 10 9 6 7 8 TDA9176 1 2 3 4 5 MBE778 100 nF YIN 100 nF UIN 100 nF VIN SC Fig.6 Application diagram for 50 Hz application with 1 Vbl-wh input signal and luminance clamping. 1996 Jan 30 11 Philips Semiconductors Preliminary specification Luminance Transient Improvement (LTI) IC TDA9176 INPUT PIN CONFIGURATION handbook, full pagewidth 100 Ω 1 MΩ fSEL 16 1 kΩ 15 14 LW 2 1 kΩ 3 1 kΩ YIN 4 VCC GND 2V 100 Ω RT Rext 1 2V 13 YOUT 1.5 mA 100 Ω 4V 100 Ω 12 UOUT 0.5 mA UIN 5 100 Ω 4V 6 100 Ω 4V 100 Ω VIN 11 10 BLI/CL 7 1 kΩ VOUT 0.5 mA TDA9176 30 kΩ 100 Ω Vref 1 MΩ SC 8 1 kΩ 100 Ω 9 AMPSEL 1 MΩ MBE781 Fig.7 Input pin configuration. 1996 Jan 30 12 Philips Semiconductors Preliminary specification Luminance Transient Improvement (LTI) IC TDA9176 PACKAGE OUTLINE DIP16: plastic dual in-line package; 16 leads (300 mil); long body SOT38-1 ME seating plane D A2 A A1 L c e Z b1 w M (e 1) b MH 9 16 pin 1 index E 1 8 0 5 10 mm scale DIMENSIONS (inch dimensions are derived from the original mm dimensions) UNIT A max.

The total contact time of successive solder waves must not exceed 5 seconds. SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “IC Package Databook” (order code 9398 652 90011). Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds. Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
