Frequently Asked Questions
What kind of static electricity precautions are required?
The manual section 1-2 advises preventing static electricity.
Which pins provide the digital/analog clock outputs for L/R channels?
Pins 2 (LRCK) and 50/54 (RO/LO) serve as output pins for respective channel clocks.
How is the system clock oscillator utilized and protected?
The system uses pin XI (input) and XO (output), and includes a dedicated GND pin XVSS3.
What data formats can AOUT and DOUT handle?
AOUT selection allows for MSB-first or LSB-first, while DOUT can output up to double-speed playback.
How is the C2 correction processing affected by setting the IPF pin?
If the IPF pin is set to 'H', AOUT output cannot be corrected by C2 correction processing.
