DESCRIPTION

Operating from a single +5 V supply, the TK15412 is a
single-channel video line driver IC that takes two standard
video analog inputs and provides one buffered analog
output for driving a 150 Ω load. The TK15412 features a
built-in 2 input/1 output video switch on the input. The
selected video input signal (1V
clamped at 1.25 V and amplified 6 dB to produce 2 V
(typical) into a series 75 Ω resistor and 75 Ω cable load.
During standby (Pin 5 grounded), the TK15412 consumes
only 125 µW of power. Nominal power dissipation (no
input) is typically 73 mW.

MEASUREMENT METHOD

1. Supply Current (ICC)
The Pin 2 current is measured with no input signal and the Standby Pin (Pin 5) open.

2. Standby Supply Current (I

STBY

)

The Pin 2 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 the Standby Pin (Pin 5) is connected to ground.

4. Standby Threshold Voltage (High to Low) (V

THL(STBY)

)

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

5. Standby Threshold Voltage (Low to High) (V

TLH(STBY)

)

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

MEASUREMENT METHOD (CONT.)

6. Switch Threshold Voltage (High to Low) (V

THL(SW)

)
The TP4 voltage is decreased very slowly. The TP4 voltage level is measured at the point where the TP1A signal is applied
to TP2 and the TP1B signal is stopped from TP2.

7. Switch Threshold Voltage (Low to High) (V

TLH(SW)

)
The TP4 voltage is increased very slowly. The TP4 voltage level is measured at the point where the TP1A signal is stopped
at TP2 and the TP1B signal is applied to TP2.

8. Clamp Voltage (V

CMP

)

The DC voltage at Pin 1 and Pin 3 is measured with no input signal.

9. Voltage Gain (GVA)
The voltage gain equation is as follows:
GVA = 20 log10 V2/V1
Where V1 is the input voltage at TP1A and TP1B, and V2 is the measured voltage at TP2.

10. Differential Gain (DG)
The differential gain is measured at TP3 when a staircase waveform of 10 steps is applied to TP1A and TP1B.

11. Differential Phase (DP)
The differential phase is measured at TP3 when a staircase waveform of 10 steps is applied to TP1A and TP1B.

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

13. Cross Talk 1 (CT1)
The cross talk 1 equation is as follows:
CT1 = 20 log10 V1/V2
When TP4 is connected to a High level, V1 is measured at TP2 when a 1 MHz 1 V
is measured at TP2 when a 1 MHz 1 V

input signal is applied to TP1B.

14. Cross Talk 2 (CT2)
