1

N/C

No Connect

No Connect. Will not respond to any input signal. When

interfacing to an MCU’s XTAL input pins, this pin is typically

connected to the receiving IC’s X Out pin. In this case, the IM890

will not be affected by the signal on this pin. If not interfacing to

an XTAL oscillator, leave pin 1 floating (no connect).

2

GND

Power Supply

Ground

Connect to ground. All GND pins must be connected to power

supply ground.

3

CLK Out

Output

Oscillator clock output. When interfacing to an MCU’s XTAL, the

CLK Out is typically connected to the receiving IC’s X IN pin. The

IM890 oscillator output includes an internal driver. As a result,

the output swing and operation is not dependent on capacitive

loading. This makes the output much more flexible, layout

independent, and robust under changing environmental and

manufacturing conditions.

4

Vdd

Power Supply

Connect to power supply 1.5V ≤ Vdd ≤ 3.63V for operation over

-40°C to +85°C temperature range. Under normal operating

conditions, Vdd does not require external bypass/decoupling

capacitor(s). Internal power supply filtering will reject more

than ±150 mVpp with frequency components through 10 MHz.
