75 Ω VIDEO LINE DRIVER

FEATURES

■ Superimpose Circuit for Two-Level (45 and 140 IRE)
Character Generation

■ Fixed Gain (6 dB)

■ Internal 75 Ω Driver with Clamp Circuit

■ Very Small Output Capacitor Using SAG Function Pin

■ Active High ON/OFF Control

■ Very Low Standby Current (typ. I

≤ 25 µA)

STBY

■ Single +5 V Power Supply Operation

DESCRIPTION

Operating from a single +5 V supply, the TK15411 is a
single-channel video line driver IC that takes a standard
video analog input and provides a buffered analog output
for driving a 150 Ω load. The standard video input signal
(1 V

typical) is internally clamped to 1.25 V and amplified

P-P

6 dB to produce 2 V
and 75 Ω cable load. The internal 1.5 kΩ SAG function
resistor provides gain compensation for low frequency
signals. The built-in superimpose circuit provides two
levels (45 and 140 IRE) of character generation to the
video signal. During standby (Pin 5 grounded), the TK15411
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. 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.

MEASUREMENT METHOD (CONT.)

5. 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.

6. Threshold Voltage (High to Low) (V

THL(SUPER)

)
The voltage at TP4 and TP5 is slowly decreased. The TP4 and TP5 voltage level is measured at the point at which the
video signal is applied to TP2.

7. Threshold Voltage (Low to High) (V

TLH(SUPER)

)
The voltage at TP4 and/or TP5 is slowly increased. The TP4 and TP5 voltage levels are measured at the point at which
the appropriate character signal per the output truth table is applied to TP2.

8. Clamp Voltage (V

CMP

)

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

9. Character Level 1 (V

CHA1

)
The character level 1 equation is as follows:
V

= (V2 - V1)/(1/140)

CHA1

Where V1 is the measured voltage at TP3 when TP4 and TP5 are at a low level and V2 is the measured voltage at TP3
when TP4 is at a high level and TP5 is at a low level. (V2 is also the voltage measured at TP3 when TP4 and TP5 are
both at high level.)

10. Character Level 2 (V

CHA2

)
The character level 2 equation is as follows:
V

= (V2 - V1)/(1/140)

CHA2

Where V1 is the measured voltage at TP3 when TP4 and TP5 are at a low level and V2 is the measured voltage at TP3
when TP4 and TP5 are at a high level.

11. 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 TP2.

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

13. Differential Phase (DP)
The differential phase is measured at TP3 when a staircase waveform of 10 steps is applied to TP1.

14. 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.
