TK15403

75 Ω VIDEO LINE DRIVER

FEATURES

■ Internal 75 Ω Drivers

■ 20 MHz Gain Band Width

■ 2 Channel High Speed Operational Amplifiers

■ Very Small SOT23L-8 Package

■ Single +5 V Power Supply Operation

DESCRIPTION

Operating from a single +5 V supply, the TK15403M is a
dual video line 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). The standard video input signals (1 V
typically amplified 6 dB using external components to
produce a 2 V

signal into an AC-coupled 150 Ω load.

P-P

Nominal power dissipation (no input) is typically 56 mW.

MEASUREMENT METHOD

1. Supply Current (ICC)
The Pin 7 current is measured with no input signal.

2. 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.

3. Frequency Response (fr1 and fr2)
The frequency response equation is as follows:
fr = 20 log10 V2/V1
Where V1 is the measured TP3 voltage when the TP1 input frequency is set to 1 MHz.
For fr1 V2 is the measured TP3 voltage when the TP1 input frequency is set to 5 MHz.
For fr2 V2 is the measured TP3 voltage when the TP1 input frequency is set to 10 MHz.
These measurements and calculations are taken for both channels.

TP2

TP3

4. Total Harmonic Distortion (THD)
The TP3 signal is measured when a 1 kHz 1 V

5. Maximum Output Voltage (V

OUT(MAX)

)

input signal is applied to TP1.

P-P

A 1 kHz input signal is applied to TP1 and slowly increased. The output voltage at TP2 is measured at the point the THD
reaches 10%.

6. Cross Talk (CT)
The Cross Talk equation is as follows:
CT = 20 log10 V1/V2
V1 is measured at output B when a 1 MHz input frequency and 1 V
measured at Output B when a 1 MHz input frequency and 1 V

P-P

input signal voltage is applied to Input A, V2 is

P-P

input signal voltage is applied to Input B.
CT is also calculated at the opposite side when V1 is measured at Output A when input signal is applied to Input B and
V2 is measured at Output A when input signal is applied to Input A.

MEASUREMENT METHOD (CONT.)

7. Signal to Noise Ratio (S/N)
The signal to noise ratio is measured at TP3 when the pedestal signal input is applied to TP1.

8. Differential Gain (DG)
SW1 is closed to change the input bias voltage.
The differential gain is measured at TP3 when a staircase waveform of 10 steps is applied to TP1.

9. Differential Phase (DP)
SW1 is closed to change the input bias voltage.
The differential phase is measured at TP3 when a staircase waveform of 10 steps is applied to TP1.
