TB1l226DN
VIDEO, CHROMA AND SYNCHRONIZING SIGNALS PROCESSING IC FOR
PAL/ NTSC/SECAM SYSTEM COLOR TV
TB1226DN 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.
TB1226DN 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, 3.58MH2 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 SDlP56-P-600-1.78
for operating the base band signal processing system. Weight : 5.55g (Typ.)
Also, TB1226DN makes it possible to set or control
various functions through the built-in IZC bus line.

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.
