Notes:
1. In OE or ST mode, a pull-up resistor of 10.0 kΩ or less is recommended if Pin 1 is not externally
driven. If Pin 1 needs to be left floating, use the NC option.
2. A capacitor of value 0.1 µF or higher between Pin 4 (Vdd) and Pin 1 (GND) is required.

Pin 1 Configuration Options (OE, or , or NC)
Pin 1 of the IM830 can be factory-programmed to support three modes: Output Enable (OE), Standby (ST) or No Connect (NC).
Output Enable (OE) Mode
In the OE mode, applying logic Low to the OE pin only disables the output driver and puts it in Hi-Z mode. The core of the device
continues to operate normally. Power consumption is reduced due to the inactivity of the output. When the OE pin is pulled High, the
output is typically enabled in <1 µSec.
Standby Mode
In the mode, a device enters into the standby mode when Pin 1 pulled Low. All internal circuits of the device are turned off. The
current is reduced to a standby current, typically in the range of a few µA. When ST is pulled High, the device goes through the
“resume” process, which can take up to 5 mSec.
No Connect (NC) Mode
In the NC mode, the device always operates in its normal mode and outputs the specified frequency regardless of the logic level
on Pin 1.
Table 1 below summarizes the key relevant parameters in the operation of the device in OE, ST, or NC mode.
Parameters
Active current 20.0 MHz (max +1.80 VDC)
OE disable current (max +1.80 VDC)
Standby current (typical +1.80 VDC)
OE enable time at 20.0 MHz (max)
Resume time from standby
(max, all frequency)
