Built-in temperature-compensated oscillator (DTCXO)! Series for automotive applications and series for consumer devices.
By utilizing our unique strengths in photolithography processing technology and circuit manufacturing technology that drives oscillators under optimal conditions, we have achieved high precision, compact size, and low current consumption (0.70µA Typ.). We offer two types of packages: the AEC-Q200 compliant automotive RA8900 series with the smallest CE package (3.2×2.5×1.0t Max. mm) compared to conventional products, and the RX8900 series for consumer devices with the SA package (10.1×7.4×3.3t Max.mm) that is size-compatible with existing products. This allows us to meet the demand for high precision in clocks and timing devices across a wide range of markets. Additionally, these products can also be used as high-precision oscillators (32.768kHz DTCXO). We adjust and guarantee frequency accuracy at the time of factory shipment, which can help improve your design efficiency and product quality. 【Features】 ○ For automotive: RA8900CE (3.2×2.5×1.0t) / RA8900SA (10.1×7.4×3.3t) ○ For consumer devices: RX8900CE (3.2×2.5×1.0t) / RX8900SA (10.1×7.4×3.3t) For more details, please contact us or download the catalog.
