Bi-CMOS Integrated Circuit Silicon Monolithic
TB1239BF
Luminance, Chroma and Synchronizing Signals Processor IC for PAL/NTSC/SECAM
COLOR TV
TB1239BF integrates luminance, chroma and synchronizing
signals processing circuits for PAL/NTSC/SECAM color TV
system.
TB1239BF incorporates high performance picture quality
compensation circuits in luminance section, an automatic
PAL/NTSC/SECAM discrimination and decode circuits in chroma
section, and an automatic 50/60 Hz discrimination circuit in
synchronizing section.
Besides a crystal oscillator generates 4.43 MHz, 3.58 MHz and
M/N-PAL clock signals internally for color demodulation. A
horizontal PLL circuit is also built in this IC.
PAL/SECAM demodulation circuits which are adjustment-free
circuits incorporates a 1 H DL circuit inside for operating the
base band signal processing system.
Also, TB1239BF makes it possible to set and to control various functions through the built-in I
2
C BUS line.

Function Description
Video Select, Auto-SW
(1) "AUTO-SW"
= (1) Manual Select
In video SW section, input signal is selected by the BUS as Figure 1 and Table 1. Mainly,
CVBS-OUT (pin 3) is used for the comb filter input, and Yvi-OUT (pin 11) is used for synchronization
(pin 2). Besides, on chroma line from video SW to main route, the peak detection is done during the
burst period. The result is responded to the Read BUS data, C ID.

External Input SWs
External inputs are selected by the BUS data and fast SWs. Final outputs from pin 21/22/23 are shown in Table 2.
RGB1-IN interface complies with SCART connector. Therefore it is active, when RGB1-IN is enable by the BUS
data and when YS3 (pin 15) is also high. The status of YS3 (pin 15) is responded to the Read BUS data, V15.

Color System
Distinguishable color systems are selected by the write BUS data, COLOR SYSTEM. The demodulated color
system is responded to the read BUS data, COLOR SYSTEM and X'TAL. (refer to BUS CONTROL FUNCTION)
The system data is also responded to Comb SYS (pin 45) and fsc-OUT (pin 46) as Table 3. If distinguishable color
system signal is not received, the system data is responded with B/W.
Besides, if pin 7 is connected to V
CC
(more than 3.5 V), Forced SECAM mode is active. In this mode, SECAM
system is identified forcibly. It has priority over the BUS selection.

Secam Bell Filter
SECAM bell filter characteristics can be changed by the BUS data, BELL/HPF. The group delay near chroma
band is corrected by changing filter characteristic. As a result, S/N looks better. Besides, center frequency f

of bell
is changed by BELL f

. Indirectly, it is changed by BPF (TOF) f

Vertical Count-Down
In Automatic of V C/D MODE, the vertical synchronization is controlled by internal PLL. In Fast mode, it is
synchronized with the inputted synchronizing signal and the pull-in time is short. Furthermore the time is shorter
in Very fast mode by the expanded pull-in range. Pull-in range of vertical count-down is determined by the BUS
data, V C/D MODE and V-FREQ as Table 4.

Note 3: 00, 11; Normal
Normal vertical input mode. It is good performance of vertical
phase keeping for standard TV signal sync. This mode is
recommended in the state of stability. And this mode can detect
teletext or VCR skew sync.
Note 4: 01; Teletext
This mode is less performance of vertical phase keeping for
standard TV signal sync against "Normal". However, pull-in
speed is faster few vertical periods than "Normal". Therefore this
mode is recommended for tesetext sync. On the other hand, this
mode can detect standard TV signal sync in the state of stability
but it is less performance of vertical phase keeping in week
signal as about
-
3 dB against "Normal".
Note 5: 10; Fast
This mode is same performance of vertical phase keeping for
standard TV signal sync of "Teletext". But it is faster pull-in
speed faster than "Teletext" because pull-in ranges wider than
"Teletext". (refer to Table 5) Therefore, this mode is better to use
when channel changing, but is not recommended to use in the
state of stability or in week signal due to too wide pull-in range
and incorrect actions of vertical keeping appearing.
Y-DL Adjustment
Table 5 shows Y output delays against Y input on condition with BPF = f
0
, Q = 2.0, Y-DL = Min and LPF = ON.
Y-out signal can be delayed by the BUS data, Y-DL. The adjustment time of one step is 40 ns.
