adjustment function and digital audio interface.
NJU26902VM1
NJU26902V
FEATURES
• 2-Channel Audio Delay (24 bits data width).
Delay Time 85msec at fs = 48kHz ( 128msec at fs = 32kHz , 43msec at fs = 96kHz)
• To make longer delay time, the NJU26902 can be connected serially.
• Non-audio-signal data can be delayed by the NJU26902.
