Features

Type

SDA 5649

SDA 5649X

Functional Description

The CMOS circuit SDA 5649 is intended for use in video cassette recorders to retrieve control data

of the PDC system from the data lines broadcast during the vertical blanking interval of a standard

video signal.

The SDA 5649 is devised to handle PDC data transported either in Broadcast Data Service Packet

(BDSP) 8/30 format 2 (bytes no. 13 through 25) of CCIR teletext system B or in the dedicated data

line no. 16 in the case of VPS.

Semiconductor Group

Single-chip receiver for PDC data, broadcast either

– in Broadcast Data Service Packet (BDSP) 8/30/2

– in dedicated line no. 16 of the vertical blanking interval

Reception of Unified Date and Time (UDT), Network

Identification code (NIC), and Short Program Label (SPL)

broadcast in BDSP 8/30/1

Reception of bytes no.38 through 45 of teletext header row

containing clock time

Low external components count

On-chip data and sync slicer

microcontroller

Selection of PDC/VPS operating mode software controlled

by I
