Circuit Operation
5.2.1.
Control-System Circuit
5.2.1.1.
IC14 (ASIC)
• EC bus interface
Independent bus for 16bit/8MHz two-way address data multiplex.
• CT bus interface
Supports eight 8.192MHz highways (128 time slots).
• Local TSW
Exchanges the time slots between CT bus (1024ch) and local highway (64ch).
• Local highway interface
Accommodates 2.048, 4.096, and 8.192MHz highways (Up to 64 time slots).
• Local gain control
Controls the gain of the local highway up-and-down 64ch in 1db step arbitrarily.
8
KX-NCP1174XJ
• CODEC interface
Can connect up to four Infineon-manufactured PEB2466, and is intended for enabling the line control.
• GPIO interface
Parallel interface that is arbitrarily programmable bidirectionally.
