DESCRIPTION
TK15404
Operating from a single +5 V supply, the TK15404 is a
single-channel video driver IC that takes a standard video
signal as the analog input and provides a buffered analog
output for driving a 150 Ω load (series 75 Ω resistor and
75 Ω cable load). The standard video input signal (1 VP-P)
is typically amplified 6 dB using external components to
produce a 2 VP-P signal into an AC-coupled 150 Ω load.
During standby (Pin 1 grounded), the TK15404 consumes
only 120 µW of power. Nominal power dissipation (no
input) is typically 32 mW.
The TK15404M is available in the very small SOT23-6
surface mount package.

MEASUREMENT METHOD
1. Supply Current (ICC)
The Pin 6 current is measured with no input signal and the Standby Pin (Pin 1) open.
2. Standby Supply Current (ISTBY)
The Pin 6 current is measured when the Standby Pin (Pin 1) is connected to ground.
3. Standby Terminal Current (IOS)
The Pin 1 current is measured when Pin 1 is connected to ground.
4. Threshold Voltage (High to Low) (VTHL)
The Pin 1 voltage is measured at the point which changes the device from operating mode into standby mode.
5. Threshold Voltage (Low to High) (VTLH)
The Pin 1 voltage is measured at the point which changes the device from standby mode into operating mode.
6. 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 output voltage at TP2.
7. Frequency Response (fr)
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 and V2 is the measured TP3 voltage
when the TP1 input frequency is set to 5 MHz. Furthermore, V1 is the measured TP3 voltage when the TP1 input frequency
is set to 1 MHz and V2 is the measured TP3 voltage when the TP1 input frequency is set to 10 MHz.

MEASUREMENT METHOD
8. Total Harmonic Distortion (THD)
The TP3 signal is measured when a 1 kHz 1 VP-P input signal is applied to TP1.
9. Maximum Output Voltage (VOUT(MAX))
A 1 kHz input signal is applied to TP1 and the amplitude is slowly increased. The output voltage at TP2 is measured at
the point the THD reaches 10%.
10. Signal to Noise Ratio (S/N)
The signal to noise ratio is measured at TP3 when a pedestal input signal is applied to TP1.
11. 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.
12. 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.
