FUNCTION TABLE OF IC
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
• Outline
YM3436D(DIR2) is a LSI which receives and demodulates the digital/audio/interface/format signals which comply with EIAJ CP-
340 and AES/EBU. Keeping the features of the existing YM3623B(DIR), it is designed to not only strengthen the external
synchronization, error process and other functions but also be more general for the channel status, user data output and other
general applications.
