Each video amplifier (R, G, and B) contains a gain set for adjusting maximum system gain (AV = 7.8 V/V). The TLS1233 provides digital level-operated contrast, brightness, and gain adjustment control. All the control inputs offer high input impedance and an operation range from 0 V to 4 V for easy interface to the serial digital buses. Provided in a 20-pin plastic dual-in-line package (DIP), the TLS1233 integrates most of the external components required to accommodate the video system. The TLS1233 operates from a 12-V supply and contains an internal input bias voltage. Also, the TLS1233 contains the feedback resistor required between output and CLAMP(–) for dc level holding. The device is characterized for operation from 0°C to 70°C. functional block diagram R VIDEO IN R CLAMP CAP R GAIN ADJUST 3 A1 4 16 V CC2 A2 18 17 1 G VIDEO IN 5 G CLAMP CAP 7 A1 A2 15 G GAIN ADJUST 14 20 B VIDEO IN B CLAMP CAP 8 CLAMP GATE R CLAMP(+) G VIDEO OUT G CLAMP(+) A1 A2 9 B GAIN ADJUST 12 CONTRAST R VIDEO OUT 13 B VIDEO OUT 19 10 Contrast Control B CLAMP(+) 11 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All VCC terminals must be externally wired together to prevent internal damage during VCC power-on/-off cycles. 2. For operation above 25°C free-air temperature, derate linearly from 1.87 W (TA = 25°C) to 1.2 W (TA = 70°C). This equates to a derating factor of 15 mW/°C. 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TLS1233 VIDEO PREAMPLIFIER SYSTEM SLVS126C – JULY 1995 – REVISED JUNE 1996 recommended operating conditions Supply voltage, VCC1 and VCC2 MIN NOM MAX 11 12 13 UNIT V V High-level input voltage range, CLAMP GATE, VIH Clamp comparators off 2.4 5 Low-level input voltage range, CLAMP GATE, VIL Clamp comparators on 0 0.8 V 0 70 °C Operating free-air temperature, TA electrical characteristics at 25°C free-air temperature range, CLAMP GATE = 0 V, CLAMP(+) = 2 V, CONTRAST = R,G,B GAIN ADJUST = 4 V, VCC1 =VCC2 = 12 V (see Figure 2) (unless otherwise noted) ALTERNATE SYMBOL PARAMETER TEST CONDITIONS MIN TYP MAX 84 94 mA 2.3 2.5 V – 0.5 -10 µA µA ICC Supply current VCC1 + VCC2 Vref Video input reference voltage Measure R/G/B video input II Contrast and R,G,B GAIN ADJUST input current Measure CONTRAST, R/G/B GAIN ADJUST Clamp gate low input current CLAMP GATE = 0 V – 0.5 – 2.4 Clamp gate high input current CLAMP GATE = 12 V 0.005 1 IIL IIH Clamp capacitor charge current IK(chg) IK(dschg) Clamp capacitor discharge current VOL VOH Low-level output voltage VO(diff) Output voltage difference High-level output voltage 2.1 R,G,B CLAMP CAP = 0 V µA 1 mA R,G,B CLAMP CAP = 5 V –1 mA R,G,B CLAMP CAP = 0 V 0.3 V R,G,B CLAMP CAP = 5 V VO(diff) UNIT 7.8 ± 0.5 Between any two channels V ± 50 mV operating characteristics at 25°C free-air temperature, CLAMP GATE = 0 V, CLAMP(+) = 4 V, CONTRAST = R,G,B GAIN ADJUST = 4 V, fI = 10 kHz, VCC1 = VCC2 = 12 V (unless otherwise noted) PARAMETER AV(max) AV(mid) Maximum voltage amplification CONTRAST = 4 V, Midrange voltage amplification CONTRAST = 2 V, VIPP = 700 mV VIPP = 700 mV Contrast voltage for minimum amplification VCONT-LOW VI(PP) = 1 V, AVmax(diff) AVmid(diff) Amplification match at AV(mid) Amplification match at AV(low) BW TEST CONDITIONS AVMAX AVMID Amplification match at AV(max) THD ALTERNATE SYMBOL AVlow(diff) V/V See Note 3 1 V CONTRAST = 4 V, See Note 4 ±0.2 dB CONTRAST = 2 V, See Note 3 ±0.2 dB ±0.2 dB 0.5 % 100 MHz 60 dB 40 dB 3 ns 4 ns CONTRAST = VCONT-LOW, See Note 3 and 4 Amplifier bandwidth Pulse test for rise time Pulse test for fall time NOTES: 3. 4. 5. 6. 7. tr tf UNIT 2 CONTRAST = 4 V, See Notes 5 And 7 ax MAX V/V CONTRAST = 1 V, Crosstalk attenuation TYP 7.8 Total harmonic distortion BW(–3 dB) MIN VIPP = 1 V CONTRAST = 4 V, See Note 6 f = 10 kHz, CONTRAST = 4 V, f = 10 MHz, See Notes 6 or 7 CONTRAST = 4 V, VO(PP) = 4 V CLAMP(+) ( ) = 2 V, See Notes 5 and 7 Determine VCONT-LOW for –40 dB attenuation of output.
