Automotive MEMS oscillators

16 August 2017 Analogue, Mixed Signal, LSI

IQD’s latest range of MEMS oscillators are designed for applications that require AEC-Q100 qualified automotive grade products. There are four models in the range to cover variations in package style, supply voltage and frequency range; all are factory programmable which ensures very short lead-times for both design-in volumes and full production.

The IQMS-116AUTO and IQMS-117AUTO models are both housed in SOT23-5 plastic packages which have the solder joints visible so they can be fully inspected. The IQMS-116AUTO has a frequency range of 1,0 MHz to 110,0 MHz and the IQMS-117AUTO a range of between 115,2 MHz and 137,0 MHz.

For customers that prefer plastic SMT packages, the IQMS-114AUTO and IQMS-115AUTO models are available in five different industry standard sizes: 2,0 x 1,6 mm, 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. The IQMS-114AUTO has a frequency range of 1,0 MHz to 110,0 MHz whilst the IQMS-115AUTO is available between 115,2 MHz and 137,0 MHz.

This new range is particularly suitable for applications such as infotainment systems, collision detection devices, in-vehicle networking and power-train control within the automotive industry, or where applications require an oscillator to operate at extreme temperatures.

All models operate over the standard automotive operating temperature range of -40°C to 125°C but can also be specified for operation over the standard industrial temperature range of -40°C to 105°C or, for applications with extreme temperatures, -55°C to +125°C. For industrial applications the IQMS-116AUTO is also available with an operating temperature range of -40°C to +85°C.

Frequency stability options can be specified down to ±20 ppm for the IQMS-114AUTO, IQMS-115AUTO and IQMS-116AUTO, and ±25 ppm for the IQMS-117AUTO over all of the operating temperature options. Five different voltage options are available – 1,8 V, 2,5 V, 2,8 V, 3,0 V and 3,3 V – with current consumption down to 4,5 mA with no load. All models deliver a CMOS output, 15 pF load with a rise and fall time of typically 2,5 ns to 3 ns, along with a duty cycle of 45/55% and the option of an enable/disable function.
