Pin Description
(cont’d)
S: supply,
I: input,
Q: output,
TTL: digital (TTL)
2
The device generates at its output an opportune sequence of 100/120 Hz fields derived
by processing the field A and the field B which are stored in 2 external field memories
and made available to the SDA 9270 on 2 separate input ports of 16 bit width each.
The device SDA 9270 generates also control signals for the SDA 9251 which are
necessary to operate the TV - SAMs in the Frame mode, that is to write the incoming
information alternatively in one or the other field memory.
Additionally the device generates a vertical sync pulse which has to be synchronized
with the respective field output. A horizontal blanking signal in phase with the output data
is also made available.
