7.5 Caution on External Components
7.6 Change of Electrical Characteristics by External Components
According to the license contract with THAT Corporation, use the following for external components.
With regard to the use of other external components, please contact to THAT corporation.
(1) SAP sensitivity can be lowered by inserting a resistor between the SDT pin and GND.
(2) Noise sensitivity can be changed by changing the value of the resistor between the NDT pin and GND.
(3) The capture range can be changed by changing the recommended 1 F value of the capacitor between the
Reducing the capacitor value increases the capture range, and increasing it reduces the capture range.
However, too small a capacitor value may cause the distortion rate to become worse during stereo output,
or may cause malfunction. In this case, please contact NEC.
