LC89075W-H SANYO [Sanyo Semicon Device], LC89075W-H Datasheet - Page 55

• Manufacturer Part Number: LC89075W-H
• Description: Digital Audio Interface Receiver with Stereo ADC and Audio Selector
• Manufacturer: SANYO [Sanyo Semicon Device]

• 0dBFS = 0.6AV DD
• The judgment levels can be adjusted from -30dBFS to -60dBFS in 2dBFS steps with the YLEVEL[3:0] and
• When performing detection on analog data, the judgment level variations can be increased by also using the
Register name
Initial value
Setting
NLEVEL[3:0] registers.
ADPGA[2:0] register that sets the PGA. However, care should be taken for the ADPGA[2:0] register setting, as it
affects the normal ADC operation.
YLEVEL[3:0]
NLEVEL[3:0]
07h
PCM data ‘Sound’ detection setting (‘Sound’ is judged when the signal is larger than the set value).
PCM data ‘Silence’ detection setting (‘Silence’ is judged when the signal is smaller than the set value).
