Preliminary
Overview
The LC74792/JM is a CMOS IC that provides PDC, VPS,
and UDT data acquisition functions. The LC74792/JM
supports microprocessor control of its operating modes
and microprocessor read out of data acquired in any of its
operating modes.
Features
• VPS data acquisition (5 or 11 to 15 bytes)
• PDC (8/30/2) data acquisition (13 to 25 bytes)
• UDT (8/30/1) data acquisition (13 to 25 bytes)
• Header (X/00) data acquisition (14 to 45 bytes)
• Status display (8/30/1, 8/30/2) data acquisition (26 to
• Automatic VPS/PDC discrimination mode
• Built-in AFC and sync separator circuits
• Synchronization discrimination circuit
