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
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. System Block Diagram Figure 1.

- LVCMOS output part number coding is always DCC
- Example part number: IM890-4DCC-32.768 Calculating Load Current No Load Supply Current When calculating no-load power for the IM890, the core and output driver components need to be added. Since the output voltage swing can be programmed for reduced swing between 250 mV and 800 mV, the output driver current is variable. Therefore, no-load operating supply current is broken into two sections; core and output driver. The equation is as follows: Total Supply Current (no load) = Idd Core + (65nA/V)(Voutpp) Example 1: Full-swing LVCMOS
- Vdd = 1.8V
- Idd Core = 900nA (typ)
- Voutpp = 1.8V (LVCMOS) Supply Current = 900nA + (65nA/V)(1.8V) = 1017nA Example 2: NanoDrive™ Reduced Swing
- Vdd = 1.8V
- Idd Core = 900nA (typ)
- Voutpp (Programmable) = VOH – VOL = 1.1V - 0.6V = 500 mV Supply Current = 900nA + (65nA/V)(0.5V) = 932nA Total Supply Current with Load To calculate the total supply current, including the load, follow the equation listed below. Note the 30% reduction in power with NanoDrive™. Total Current = Idd Core + Idd Output Driver (65nA/V*Voutpp) + Load Current (C*V*F

- Vdd = 1.8V
- Idd Core = 900nA
- Load Capacitance = 10pF
- Idd Output Driver: (65nA/V)(1.8V) = 117nA
- Load Current: (10pF)(1.8V)(32.768kHz) = 590nA
- Total Current = 900nA+117nA+590nA = 1.6µA Example 2: NanoDrive™ Reduced Swing
- Vdd = 1.8V
- Idd Core = 900nA
- Load Capacitance = 10pF
- Vout pp (Programmable): VOH – VOL = 1.1V - 0.6V = 500mV
- Idd Output Driver: (65nA/V)(0.5V) = 33nA
- Load Current: (10pF)(0.5V)(32.768kHz) = 164nA
- Total Current = 900nA + 33nA + 164nA = 1.1µA
