Product Overview
The SG-8018 series crystal oscillators offer a wide frequency range from 0.67 MHz to 170 MHz with 1 ppm step programmability. Designed for high reliability and performance, these oscillators feature a supply voltage range of 1.62 V to 3.63 V and a frequency tolerance of 50 ppm over an operating temperature range of -40 C to +105 C. Key functionalities include Output Enable (OE) and Standby (ST) modes, making them suitable for various applications requiring precise clock generation. The series utilizes PLL technology for short lead times and is compatible with the SG-Writer II field oscillator programmer. Available in multiple package sizes, these oscillators are RoHS compliant and designed for surface mount applications.

Pin Description
| Pin Name | I/O Type | Function |
|---|---|---|
| OE | Input | Output enable: High: Specified frequency output from OUT pin; Low: Out pin is low (weak pull down), only output driver is disabled. |
| ST | Input | Standby: High: Specified frequency output from OUT pin; Low: Out pin is low (weak pull down), Device goes to standby mode. Supply current reduces to the least as I_std. |
| GND | Power | Ground |
| OUT | Output | Clock output |
| VCC | Power | Power supply |
