DESCRIPTION

Operating from a single +5 V supply, the TK15400 is a triple video line driver IC that takes standard Y/C analog inputs and provides simultaneous Y/C and composite analog outputs for driving 75 Ω lines. Internal summing of the Y and C inputs is performed to produce the composite video output. The luminance (Y) input is clamped at

1.25 V and amplified 6 dB to produce 2 V a series 75 Ω resistor and 75 Ω cable load. The internal

1.5 k SAG function resistor provides gain compensation for low frequency signals. The chromanance (C) input is biased at 2.0 V and amplified 6 dB to produce 1.3 V (typical) into a series 75 Ω resistor and 75 Ω cable load. During standby (Pin 5 grounded), the TK15400 consumes only 113 µW of power. Nominal power dissipation (no input) is typically 168 mW.

The TK15400M is available in the SSOP-12 Surface Mount Package.

MEASUREMENT METHOD

1. Supply Current (ICC) The Pin 1 current is measured with no input signal and the Standby Pin (Pin 5) open.

2. Standby Supply Current (I

STBY

)

The Pin 1 current is measured when the Standby Pin (Pin 5) is connected to ground.

3. Standby Terminal Current (IOS) The Pin 5 current is measured when Pin 5 is connected to ground.

4. Threshold Voltage (High to Low) (V

THL

)

The Pin 5 voltage is measured at the point which changes the device from operating mode into standby mode.

5. Threshold Voltage (Low to High) (V

TLH

)

The Pin 5 voltage is measured at the point which changes the device from standby mode into operating mode.

6. Clamp Voltage (V

CMP

)

The DC voltage at Pin 2 is measured with no input signal.

MEASUREMENT METHOD (CONT.)

7. Bias Voltage (V

BIAS

)

The DC voltage at Pin 6 is measured with no input signal.

8. Voltage Gain (GVA) The voltage gain equation is as follows: GVA = 20 log10 V2/V1 Where V1 is the input voltage at TP1 and V2 is the measured voltage at TP5 (TP7). Furthermore, V1 is the input voltage at TP2 and V2 is the measured voltage at TP3 (TP5).

9. Differential Gain (DG) The differential gain is measured at TP5 (TP7) when a staircase waveform of 10 steps is applied to TP1.

10. Differential Phase (DP) The differential phase is measured at TP5 (TP7) when a staircase waveform of 10 steps is applied to TP1.

11. Frequency Response (fr) The frequency response equation is as follows: fr = 20 log10 V2/V1 Where V1 is the measured TP7 voltage when the TP1 input frequency is set to 1 MHz and V2 is the measured TP7 voltage when the TP1 input frequency is set to 5 MHz. Furthermore, V1 is the measured TP3 (TP5) voltage when the TP2 input frequency is set to 1 MHz and V2 is the measured TP3 (TP5) voltage when the TP2 input frequency is set to 5 MHz.

12. Cross Talk 1 (CT1) The cross talk equation is as follows: CT1 = 20 log10 V1/V2 Where V1 is measured at TP3 when a 1 MHz 1 V MHz 1 V

input signal is applied to TP2.
