GENERAL DESCRIPTION
The TDA2506/T converts colour-difference signals (DR and DB) into sequential, frequency modulated signals according to the SECAM system.

FEATUREs
● Chrominance processor
● Vertical identification signal generator
● Timing pulse output to TDA2507
● Sample and hold circuit for control signal from TDA2507
● No adjustments of external components required (except high-frequency pre-emphasis (bell filter) stage)
