Multistandard hybrid IF processing
[1]
Values of video and sound parameters can be decreased at VP = 4.5 V.
[2]
Condition for secure POR is a rise or fall time greater than 2
s.
[3]
This parameter is not tested during the production and is only given as application information for designing the receiver circuit.
[4]
Level headroom for input level jumps during gain control setting.
[5]
BLF(3dB) = 100 kHz (damping factor d = 1.9; calculated with sync level within gain control range). Calculation of the VIF PLL lter can be
done by use of the following formula:
, valid for d
≥ 1.2
,
where:
KO is the VCO steepness
or
; KD is the phase detector steepness
;
R is the loop lter serial resistor (
); C is the loop lter serial capacitor (F); B
LF(
3dB) is the 3 dB LF bandwidth (Hz); d is the damping
factor.
[6]
The VCO frequency offset related to the PC frequency is set to 1 MHz with white picture video modulation.
[7]
AC load; CL < 20 pF and RL >1k. The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound
carrier traps.
[8]
Condition: luminance range (5 steps) from 0 % to 100 %. Measurement value is based on 4 of 5 steps.
[9]
Measurement using 200 kHz high-pass lter, 5 MHz low-pass lter and subcarrier notch lter (
“ITU-T J.64”).
[10] Modulation VSB; sound carrier off; fvideo > 0.5 MHz.
[11] Sound carrier on; fvideo = 10 kHz to 10 MHz.
[12] The sound carrier trap can be bypassed by setting the I2C-bus bit W2[0] to logic 0; see Table 24. In this way the full composite video
spectrum appears at pin CVBS. The video amplitude is reduced to 1.1 V (p-p).
[13] Measurement condition: with transformer, transmitter pre-correction on; reference is at 1 MHz.
[14] The response time is valid for a VIF input level range from 200
Vto70mV.
[15] See Figure 19 to smooth current pulses.
