Product Overview
The SG-8018 series crystal oscillator offers a frequency range from 0.67 MHz to 170 MHz with 1 ppm step resolution. It operates with a supply voltage range of 1.62 V to 3.63 V and features an output enable (OE) or standby (ST) function. The frequency tolerance is 50 ppm across the operating temperature range of -40 C to +105 C, including frequency aging over 10 years at +25 C. These oscillators utilize PLL technology for short lead times and are compatible with the "SG-Writer II" field oscillator programmer. They are available in various package sizes, including 2.5 x 2.0 mm, 3.2 x 2.5 mm, 5.0 x 3.2 mm, and 7.0 x 5.0 mm.
