Product data sheet
The SECAM processing contains the following blocks:
The burst processing block provides the feedback loop of the chrominance PLL and
contains:
The chrominance comb filter block eliminates crosstalk between the chrominance
channels in accordance with the PAL standard requirements. For NTSC color standards
the chrominance comb filter can be used to eliminate crosstalk from luminance to
chrominance (cross-color) for vertical structures. The comb filter can be switched off if
desired. The embedded line delay is also used for SECAM recombination (cross-over
switches).
The resulting signals are fed to the variable Y-delay compensation and the output
interface, which contains the VPO output formatter and the output control logic

Baseband ‘bell’ filters to reconstruct the amplitude and phase equalized 0 and 90
FM signals
Phase demodulator and differentiator (FM-demodulation)
De-emphasis filter to compensate the pre-emphasized input signal, including
frequency offset compensation (DB or DR white carrier values are subtracted from the
signal, controlled by the SECAM switch signal).
Burst gate accumulator
Color identification and color killer
Comparison nominal/actual burst amplitude (PAL/NTSC standards only)
Loop filter chrominance gain control (PAL/NTSC standards only)
Loop filter chrominance PLL (only active for PAL/NTSC standards)
PAL/SECAM sequence detection, H/2-switch generation
Increment generation for DTO1 with divider to generate stable subcarrier for
non-standard signals.
