Product Overview
The SG-9101 series is a programmable crystal oscillator featuring CMOS output, designed for a wide frequency range from 0.67 MHz to 170 MHz with 1 ppm step resolution. It supports supply voltages from 1.62 V to 3.63 V and offers flexible output enable (OE) or standby (ST) functions. This series utilizes PLL technology for short lead times and supports both Down and Center spread modulation with configurable spreading parameters, including modulation profile (Hershey-kiss, Sine-wave, Triangle), modulation frequency, and spread percentage. It is available in various package sizes and is designed for applications requiring high reliability, including automotive systems.

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 |
