RV-2123-C2
The RV-2123-C2 is soldered onto the Development Board.
Every pin is either accessible at test pins 1 – 10 or at the test vias situated around the device.
The following passive components are already soldered on the Board:
C1
10 nF
Decoupling capacitor between V
SS
and V
DD
R1
330 Ω
current limiting resistor for LED
LED1 green
Supply, current consumption of the LED has to be considered
R2
10 kΏ
Pull-up resistor CLKOUT to V
DD
R3
10 kΏ
Pull-up resistor INT to V
DD
R4
10 kΏ
Protection resistor to prevent short-circuit between external CLKOE signal and Jumper.
