''AN APPARATUS TO INTERFACE GRAPHIC CONTROLLER CHIP WITH MULTI-SYNC SVGA MONITORS''

摘要

An apparatus for interfacing graphic controller chip with multi-sync SVGA monitor to provide performance comparable to RGB monitor characterise in that a sync separator/amplifier (5) separates sync signal from (SOG) sync on green and adapted to receive signals from a graphic controller chip (1), a buffer plus phase inverter (6), reduces loading and phase inverts the composite sync signal received from sync separator / amplifier, connected to the output of said amplifier, (TTL) Transistor transistor logic level converter (7) connected to said buffer phase inverter, a buffer (8) which buffers the composite sync signal received from (TTL) Transistor Transistor Logic level converter (7) into Horizontal sync (H Sync) signal, connected to said converter, integrator and emitter follower (9) connected to said converter, said follower connected to said buffer through two inverters (11) and (12).
