TB1227CNG
VIDEO, CHROMA AND SYNCHRONIZING SIGNALS PROCESSING IC FOR PAL / NTSC
/ SECAM SYSTEM COLOR TV
TB1227CNG that is a signal processing IC for the PAL / NTSC /
SECAM color TV system integrates video, chroma and
synchronizing signal processing circuits together in a 56-pin
shrink DIP plastic package.
TB1227CNG incorporates a high performance picture quality
compensation circuit in the video section, an automatic PAL /
NTSC / SECAM discrimination circuit in the chroma section, and
an automatic 50 / 60Hz discrimination circuit in the
synchronizing section. Besides a crystal oscillator that internally
generates 4.43MHz, 3.58MHz and M / N-PAL clock signals for
Weight: 5.55 g (typ.)
color demodulation, there is a horizontal PLL circuit built in the
IC.
The PAL / SECAM demodulation circuit which is an adjustment-free circuit incorporates a 1H DL circuit inside for
operating the base band signal processing system.
Also, TB1227CNG makes it possible to set or control various functions through the built-in I2C bus line.

Data receive format
At the moment of the first acknowledge, the master transmitter becomes a master receiver and the slave
receiver becomes a slave transmitter. This acknowledge is still generated by the slave.
The STOP condition is generated by the master.
Optional data transmit format : Automatic increment mode
In this transmission method, data is set on automatically incremented sub-address from the specified
sub-address.
Purchase of TOSHIBA I2C components conveys a license under the Philips I2C Patent Rights to use these
components in an I2C system, provided that the system conforms to the I2C Standard Specification as
defined by Philips.

While shifting color phase (tint) from minimum to maximum by the bus control, measure
phase change of B-Y color difference output of pin 36. On the condition that 6 bars in
the center have the peak level (regarded as center of color phase), the side of 5 bars is
regarded as positive direction while the side of 7 bars is regarded as negative direction

Based on this assumption,open angle toward the
positive direction is expressed as ∆θ1 and that
toward the negative direction is expressed as ∆θ2 as
viewed from the phase center. ∆θ1 and ∆θ2 show

(1)
The same procedure as the step 1 of the Note S5.
(2)
Measure and calculate amplitude of black bar
levels in output waveforms of pin 35 and pin 36 as
shown below.
LinB = V [cyan] / V [red]
Maximum positive /
negative amplitudes in
respective axes
LinR = V [yellow] / V [blue]

(1)
The same procedure as the step 1 of the Note S5.
(2)
Measure output waveforms of pin 35 and pin 36
to find the period between the two points shown in
the figure in time.
(3)
In the condition that SUB (IF) D5 = 1, perform the
same measurement as the above step 2.
Measurement results are expressed as trfBW and
trfRW.
(1)
Input 200mVp-p (R-Y ID) standard 75% color bar
signal (SECAM system) to pin 42.
(2)
Attenuate the input signal to pin 42. Measure R-Y
ID signal level at pin 42 that turns on / off the killer
as eSK and eSC.
(3)
In the condition that SUB (IF) D3 = 1, perform the
same measurement as the above step 2 and
express the measurement results as eSFK and
eSFC.
(4)
In the condition that SUB (IF) D3 = 0, D2 = 1,
perform the same measurement as the above
step 2 and express the measurement results as
eSWK and eSWC.
