Mounting AD Conversion Capacitors and Oscillators
The capacitor pattern for 38K0/38K2 AD conversion is located on the upper left side of both G02 and G03 (1).
To evaluate AD conversion, mount 0.1uF chip capacitors (size “1608”) here.
The 38K0/38K2 oscillator sockets are located on the left side of both G02 and G03 (2). Insert the bundled
oscillator (6MHz or 12MHz, as required)
(Note 1)
, and a 30pF oscillator capacitor.
Note 1: The margin of error for the USB Full-speed data rate is 0.25% (2,500ppm) at 12MB/s. Select a crystal oscillator that can guarantee the same.
1.Capacitor Mounting Pattern
When evaluating AD conversion, insert
0.1uF chip capacitors.
2. Oscillation Circuits
Insert 6MHz or 12Mhz crystal
oscillator here, in accordance
with user program.
