Preliminary Device Specification
TV signal processor-Teletext decoder with
embedded
μ
-Controller
TDA935X/6X/8X series
Table 56
Colour decoder mode, note 1
Note
1.
The decoder frequencies for the various standards are
obtained from an internal clock generator which is
synchronised by a 12 MHz reference signal which is
obtained from the
μ
-Controller clock generator.
These frequencies are:
a) A: 4.433619 MHz
b) B: 3.582056 MHz (PAL-N)
c) C: 3.575611 MHz (PAL-M)
d) D: 3.579545 MHz (NTSC-M)

The result of this setting depends on the version
(FM-PLL or QSS type). The various possibilities are
given in table 1.
