DESCRIPTION

Operating from a single +5 V supply, the TK15407 is a dual
video driver IC that takes standard video signals as analog
inputs and provides buffered analog outputs for driving
150 Ω loads (series 75 Ω resistor and 75 Ω cable load).
Both amplifiers have a fixed gain of 6 dB and can be used
in series for 12 dB gain. The luminance (Y) input is
clamped at 1.29 V and amplified 6 dB to produce 2 V
(typical) into 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 2.6 V and amplified 6 dB to produce

1.1 V

(typical) into a series 75 Ω resistor and 75 Ω cable

P-P

load. During standby (Pin 3 grounded), the TK15407
consumes only 119 µW of power. Nominal power
dissipation (no input) is typically 76 mW. The TK15407 is
ideally suited for S-VHS systems.

The TK15407M is available in the very small SOT23L-8
surface mount package.

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

4. Threshold Voltage (High to Low) (V
The Pin 3 voltage is measured at the point which changes the device from operating mode into standby mode.

5. Threshold Voltage (Low to High) (V
The Pin 3 voltage is measured at the point which changes the device from standby mode into operating mode.

6. Clamp Voltage (V
The DC voltage at Pin 2 is measured with no input signal.

7. Bias Voltage (V
The DC voltage at Pin 4 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 (TP4) and V2 is the measured voltage at TP2 (TP5).

9. Differential Gain (DG)
The differential gain is measured at TP3 when a staircase waveform of 10 steps is applied to TP1.

MEASUREMENT METHOD (CONT.)

10. Differential Phase (DP)
The differential phase is measured at TP3 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 TP3 (TP6) voltage when the TP1 (TP4) input frequency is set to 1 MHz and V2 is the measured
TP3 (TP6) voltage when the TP1 (TP4) input frequency is set to 5 MHz.

12. Total Harmonic Distortion (THD)
The TP6 signal is measured when a 1 kHz 1 V

input signal is applied to TP4.

P-P

13. Maximum Output Voltage (V
A 1 kHz input signal is applied to TP4 and the amplitude is slowly increased. The output voltage at TP5 is measured at

OUT(MAX)

)

the point the THD reaches 10%.
