Figure. Typical delay-time (group delay @ 1MHz) characteristics of prefilter due to
BANDWIDTH data.
Note on 1125/50p/60p input
When 1125/50p and/or 60p signal are input, GAIN = 0(0dB) and FILPASS = 0(ON) are recommended due to the
performance of the slew rate and cutoff frequency of the TB1305FG and TB1308FG circuits. A gain amplifier and/or a
prefilter for 1125/50p/60p should be added as external circuits, if necessary.
Note on video output pins
To conduct the video signal from the TB1305FG or TB1308FG to the following circuits, a buffer such as the one in
the application circuits is required due to the drive capability of the TB1305FG and TB1308FG being insufficient,
especially for high-frequency components.
The DC levels of the video output vary according to I
2CBUS functions, the APL of the input and temperature
drift.Therefore, the DC levels should be re-clamped in connected circuits such as AD converters.
Recommended crystal oscillator
When a connected crystal oscillator is used for the XO, the following oscillation specifications are required.
Oscillation frequency (fundamental): 3.579545 MHz (for NTSC decoding)
Frequency tolerance: +/- 50 ppm
External CW input into crystal oscillator pin
Instead of connecting a crystal oscillator, it is possible to input an external CW (Continual Wave) into pin 21 through a
capacitor as below.
The specifications required for CW input are as follows.
Input frequency (fundamental): 3.579545 MHz +/- 50 ppm
Input amplitude: 1.0 Vp-p +/- 0.5 Vp-p
