DESCRIPTION
Output of Bb channel (B or b sensor output depending upon SW
position).
Output of Aa channel (A or a sensor output depending upon SW
position).
Mode switch input. High logic level selects CD mode, low - DVD mode.
Output of RF channel. RF = A + B + C + D or RF = a + b + v + d
depending upon SW position.
No Connection.
Output of Dd channel (D or d sensor output depending upon SW
position.
Output of Cc channel (C or c sensor output depending upon SW
position)
No Connection.
Ground Pin.
Output of F Channel.
No Connection.
Reference Voltage. Bypass to GND with ceramic capacitor 0.1µF.
Supply Voltage. Bypass to GND with ceramic capacitor 0.1µF.
Output of E Channel.
No Connection.
Ground Pin.
BOARD LAYOUT AND GROUNDING
To obtain the best performance from the SP8042, a printed circuit board with ground plane is required.
Both ground pins (pins #9 and #16) should be connected to the ground plane. High quality, low series
resistance ceramic 0.1µF bypass capacitors should be used at the VCC and VS pins (pins 12 and 13).
These capacitors must be located as close to the pins as possible.
The traces connection the pins to the ground plane, VCC, VS, and bypassing capacitors must be kept
short and should be made as wide as possible.
