RV-3029-C3
The RV-3029-C3 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 Ώ
current limiting resistor for LED
LED green
Supply, current consumption of the LED has to be considered
R2
10 kΏ
Pull-up resistor SCL to V
DD
R3
10 kΏ
Pull-up resistor SDA to V
DD
R4
10 kΏ
Pull-up resistor INT to V
DD
R5
10 kΏ
Protection resistor to prevent short-circuit between external CLKOE signal and Jumper.

Description
CLKOUT enable/disable pin; enable is active HIGH; tie to GND when not using CLKOUT
Positive supply voltage;
positive or negative steps in supply voltage may affect oscillator performance,
recommend 10 nF decoupling capacitor close to device
Clock Output pin. CLKOUT or INT function can be selected.(Control_1; bit7; CLK/INT)
CLKOUT output push-pull / INT function open-drain requiring pull-up resistor
Serial Clock Input pin; requires pull-up resistor
Serial Data Input-Output pin; open-drain; requires pull-up resistor
Ground
Interrupt Output pin; open-drain; active LOW
Not Connected; internally used for test, do not connect other signals then ground.
Backup Supply Voltage; tie to GND when not using a backup supply voltage.
Not Connected; internally used for test, do not connect other signals then ground.
