AEL Crystals offers MEMS oscillators from SiTime
The Internet of Things (IoT) puts increased demands on systems with the requirement for frequency control across multiple wireless communications protocols – Bluetooth, ZigBee, Z-Wave, 6LoWPAN, CSR Mesh, Bluetooth Low Energy, Sigfox and Thread. AEL Crystals has added SiTime MEMS oscillators to its range. SiTime’s silicon-based MEMS oscillators join AEL’s existing range of products designed for the IoT.
The Internet of Things (IoT) brings a new dimension to frequency control, as it uses multiple protocols (Bluetooth®, ZigBee, Z-Wave, 6LoWPAN, CSR Mesh / Bluetooth Low Energy (LE), Sigfox and Thread). At the same time, there is the demand for increasing miniaturisation, reducing power consumption and providing consistent performance over a broad operating specification.
The SiT15xx 32.768 kHz MEMS timing solutions are designed for mobile, IoT and wearable applications where space and power are critical. SiTime MEMS oscillators offer high levels of integration, packaging options and space savings, with surface mount and ultra-small chip-scale package (CSP) choices.
A particular benefit for IoT applications is the clocking for monitoring circuitry. The real-time clock (32.768 kHz) is always-on, contributing to extending the life of the battery.
The MEMS oscillators are available in a 2.0mm by 1.2mm (2012) SMD package for designs that require crystal resonator compatibility. The CSP MEMS oscillator reduces footprint by up to 80 percent compared to existing 2012 SMD crystal packages and is 60 percent smaller than the 1610 crystal package (1.6mm by 1.0mm).
In addition to real time clock (RTC) products, SiTime offers the SiT8021, the industry’s smallest and the lowest power MHz oscillator in a 1.5mm by 0.8mm CSP. This oscillator is suitable for battery-operated applications, with low operating power of 270µA (max) and ≤0.7µA in standby mode.
The programmable technology ensures that samples are availability from stock in all frequencies.
AEL Crystals’ existing range includes: 1.6mm by 1.6mm watch crystals (with ESR as low as 60kΩ); 1.6mm by 1.2mm 32.768Hz oscillators; 1.6mm by 1.0mm AT-cut crystal resonators; 1.2mm by 1.0mm AT-cut crystal resonators and 1.6mm by 1.2mm clock oscillators, all designed to support development for IoT applications.
AEL Crystals also supports customers with ultra-miniature TCXO, antenna and filter devices.
