SILICON MONOLITHIC
TB1245N
VIDEO, CHROMA AND SYNCHRONIZING SIGNALS PROCESSING IC FOR
PAL / NTSC / SECAM SYSTEM COLOR TV
TB1245N 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 56pin
shrink DIP plastic package.
TB1245N 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 / 60 Hz discrimination circuit in the
synchronizing section. Besides a crystal oscillator that internally
generates 4.43 MHz, 3.58 MHz and M / N-PAL clock signals for
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, TB1245N 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.

Note 1: In the condition that IC is actually mounted. See the diagram below.
Note 2: This IC is not proof enough against a strong E-M field by CRT which may cause function errors and / or poor
characteristics.
Keeping the distance from CRT to the IC longer than 20 cm, or if cannot, placing shield metal over the IC, is
recommended in an application.

(5)
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
when the 5 bars or the 7 bars are in the peak level. 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 the tint control sharing
range.

The same procedure as the steps 1 and 2 of the
Note S5.
(2)
In the condition that SUB (IF) D6 = 1, measure
amplitudes of color difference signals of pin 35
and pin 36 as VRSA and VBSA respectively, and
find SATTR and SATTB from measurement
results.

SATTR = 20 ℓog (VRSA / VRS),
SATTB = 20 ℓog (VBSA / VBS)

(2)
Input non-modulated 200 Vp-p (R-Y) chroma
signal to pin 42.
(3)
Measure noise amplitude nR and nB (mVp-p)
appearing in color difference signals of pin 35 and
pin 36 respectively.
(4)
Find S / N ratio by the following equation.
SNB - S = 20log (2 2 × VBS / nB × 10E - 3)
SNR - S = 20log (2 2 × VRS / nR × 10E - 3)
