SINGLE CHIP DIGITAL TUNING SYSTEM FOR 3 DISC CD CHANGER
TC9309AF-125 is a CMOS LSI designed for a PLL frequency synthesizer radio system corresponded to
the requirement of 2 areas.
Since TC9309AF-125 can be used for TC9284BF the CD processor and receive remote control signal,
a low cost compact 3 CD with radio system can be constructed.
