The IDG-2020 and IXZ-2020 are single-chip, digital output, 2 Axis MEMS gyroscope ICs which feature a 512-byte FIFO. In applications such as Electronic Image Stabilization, the gyro output is sampled at a fast rate, e.g.1 KHz, but is only needed at the video frame rate (ex: 30 fps). The FIFO can store the samples within a frame, lower the traffic on the serial bus interface, and reduce power consumption by allowing the system processor to burst read sensor data and then go into a low-power mode. The FSYNC (Frame Sync) input allows precise timing to be achieved with Video Frame Sync at the host level for read out of the frame data.
The OIS gyros include specific features to enhance OIS performance including a narrow programmable full-scale range of ±31.25, ±62.5, ±125, and ±250 degrees/sec, fast sampling of the gyro output at up to 32KHz, low phase delay including fast 20MHz read out through SPI interface, very low Rate noise at 0.0065 dps/√Hz and extremely low power consumption at 2.9 mA for 2 axis operation. Factory-calibrated initial sensitivity reduces production-line calibration requirements.
Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, a precision clock with 1% drift from -40°C to 85°C, an embedded temperature sensor, and programmable interrupts. The device features I2C and SPI serial interfaces, a VDD operating range of 1.71 to 3.6V, and a separate digital IO supply, VDDIO from 1.71 V to 3.6 V.
