Universal sync generator (USG)
SAA1101
FUNCTIONAL DESCRIPTION
Generation of pulses
Generation of standard pulses such
as sync, blanking and burst for TV
systems: PAL B/G, PALN, PALM,
SECAM and NTSC. In addition a
number of non-standard pulses have
been supplied to simplify signal
processing. These signals include -
horizontal drive, vertical drive, clamp
pulse, identification etc. It is possible
to select the 524/624 line mode
instead of the 525/625 line mode for
all the above TV systems for
applications such as robotics, games
and computers.
