SYSTEM CONNECTION DIAGRAM
1) Power and Ground
To get the most out of analog performance, it is necessary to split the ground into analog and digital blocks.
Analog ground and digital ground earth at one point closed to the initial ground supply of the board. The
layout of the ground pattern should be designed as large as possible and the impudence should be reduced to
prevent from receiving ambient noise. In addition, use 0.1
mF and 47mF capacitors to connect between the
analog voltage pin and the analog ground as well as between the digital supply pin and the digital ground.
2) Reference Voltage
As the reference voltage determines all analog signals’ reference levels of YMF752, noise generated from
the reference voltage could affect the YMF752’s analog performance. To stabilize the YMF752’s reference
voltage, insert a 0.1
mF ceramic capacitor in parallel with a 10mF capacitor between Vref pin and the ground.
The 0.1
mF ceramic capacitor should be designed as close to the Vref pin as possible
3) Master Clock
To suppress the master clock from affecting its surroundings, it is recommended to keep the master clock
guarded on the ground so the noise can be reduced.
4) Unused Analog Input / Output pins
For the unused analog input pins, short them through a 0.1
mF ceramic capacitor to the analog ground. For
the unused analog output pins, they should be left opened.
