Allowable Operating Ranges
at Ta = 25°C
Note 1. The input signal must be input with low impedance for correct operation of sync-tip clamping.
Electrical Characteristics
at Ta = 25°C, V
DD
= 5.0 V, CLK = 3.579545 MHz; 300 mV p-p
Test Conditions
1. The supply current with no input signal
2. The following formula is used to calculate the voltage gain (G
V
).
V
[mVp-p]
500 [mVp-p]
G
V
= 20log ——————— [dB]
3. The following formula is used to calculate the frequency characteristics (Gf).
V2 [mVp-p]
V1 [mVp-p]
G
f
= 20log —————— [dB]
During this test, adjust Vbias so that the input signal DC level is 250 mV higher than the clamp level.
