ANALOG CHARACTERISTICS (VIDEO)
(Ta=25

C; AVDD = VVDD1-2 = 5V, DVDD =3.3V; AVSS = VVSS1-3 = DVSS = 0V; unless otherwise specified)
Parameter
Conditions
Sync Tip Clamp Voltage
(Note: 12)
Gain (Note: 13)
Input=0.3Vp-p, 100kHz
Frequency Response (Note: 13)
Input=0.3Vp-p, 100kHz to 6MHz.
Maximum Input Signal
f=100kHz, maximum with distortion < 1.0%,
gain=6dB(typ).
Load Resistance
R1+R2(Note: 14)
Load Capacitance
C1 (Note: 14)
C2 (Note: 14)
Interchannel Isolation (Note: 15) f=4.43MHz, 1Vpp input.
S/N
Reference Level = 0.7Vpp, CCIR 567
weighting. BW= 15kHz to 5MHz.
Differential Gain
0.7Vpp 5steps modulated staircase.
chrominance &burst are 280mVpp, 4.43MHz.
Differential Phase
0.7Vpp 5steps modulated staircase.
chrominance &burst are 280mVpp, 4.43MHz.
Input Detection Circuit
Input Reception (Note: 16)
Note: 12. SAGN bit=“1”, DC output. There is no specification for using the Sag Compensation circuit (SAGN bit=“0”).
Sync Tip Clamp Voltage is proportional to AVDD voltage, VOUT=0.17 x AVDD V(typ).
Note: 13. If SAGN bit=“0” for using the Sag Compensation circuit, the measurement point is between C3 and R1 of
Figure 5. If SAGN bit=“1” for DC output, the measurement point is video output pin.
Note: 14. See Figure 5 and Figure 6.
Note: 15. Between all channels of VIN1-6.
Note: 16. If the input voltage is smaller than the detection reception value, the signal isn’t detected. If the input voltage is
larger than the detection reception value, the signal is detected. The input reception value is proportional to
AVDD voltage, 0.014 x AVDD Vpp(typ).
