Product Series
| The SiTime SiT1602B is a low-power fixed-frequency MEMS oscillator for portable, consumer, storage, and networking systems. It offers 52 standard frequencies from 3.57 to 77.76 MHz with an LVCMOS/HCMOS-compatible output. Total frequency-stability options of ±20, ±25, and ±50 ppm include initial tolerance at 25°C, first-year aging at 25°C, and variation over operating temperature, rated supply voltage, and load. Designers can specify extended commercial operation from -20°C to +70°C or industrial operation from -40°C to +85°C. Fixed supply-voltage options include 1.8, 2.5, 2.8, 3.0, and 3.3 V, while continuous-range options span 2.25 V to 3.63 V and 1.62 V to 3.63 V. At 1.8 V and 20 MHz with no output load, the device draws 3.5 mA typical active current. In standby mode with pin 1 pulled low, typical standby current is 0.6 µA at a 1.8 V supply. FlexEdge™ configurable drive strength adjusts output rise and fall times for the capacitive load, helping reduce oscillator-generated EMI. The gated output reaches rated frequency stability on the first pulse and avoids runt pulses and startup glitches. Five industry-standard package sizes, pin-to-pin compatibility with quartz oscillators, and Time Machine II support simplify qualification, prototyping, and inventory planning. |

| The SiTime SiT8008B is a low-power programmable MEMS oscillator for consumer, networking, industrial, medical, and storage systems. It supports any frequency from 1 to 110 MHz with six decimal places of accuracy and an LVCMOS/HCMOS-compatible output. Total frequency-stability options of ±20, ±25, and ±50 ppm include initial tolerance at 25°C, first-year aging at 25°C, and variation over operating temperature, rated supply voltage, and load. Designers can specify extended commercial operation from -20°C to +70°C or industrial operation from -40°C to +85°C. Fixed supply-voltage options include 1.8, 2.5, 2.8, 3.0, and 3.3 V, while continuous-range options span 2.25 V to 3.63 V and 1.62 V to 3.63 V. At 1.8 V and 20 MHz with no output load, the device draws 3.5 mA typical active current. Standby mode shuts down the internal circuitry and reduces typical current to less than 1 µA at 1.8 V. Startup and resume times remain within 5 ms. FlexEdge™ configurable drive strength lets designers adjust output rise and fall times for the capacitive load, reducing oscillator-generated EMI and supporting capacitive loads of 60 pF or higher with the appropriate drive-strength setting. The gated output reaches rated frequency stability on the first pulse and avoids runt pulses and startup glitches. Five industry-standard package sizes, pin-to-pin compatibility with quartz oscillators, and Time Machine II support simplify qualification, prototyping, and inventory planning. |
