Pin Descriptions
Pins 1 and 24
Pins 1 and 24 are frequency control pins for the correction signal. If the capacitors C1 and C2 were not connected to pins
1 and 24, when correction was applied to signals that include noise as shown in the figure below, the noise level would
increase. Accordingly, the capacitors C1 and C2 are used to reduce the high frequencies so that high-frequency noise
levels are not aggravated. (frequency-adaptive type circuit)
C1 is provided for when the gain is increased, and C2 for when the gain is decreased. About 2 MHz when C = 82 pF.
No. 5097-4/11
