Distributor matches Kyocera crystals to Nordic wireless ICs

August 28, 2015 // By Graham Prophet
With six qualified crystal units, Kyocera supports Nordic Semiconductor’s nRF51 series of multi-protocol SoC devices for ultra-low power wireless applications. The crystal units are available at distributor Rutronik.

Nordic’s device family is built around a 32-bit ARM Cortex M0 processor core. For this processor, Kyocera offers six qualified crystal units with frequencies of 16 MHz or 32 MHz for the mandatory clock and 32.768 kHz as an optional usage for Power Save.

The MHz crystals are available in a 4-pad 2.00 x 1.60 mm (CX2016DB) or 2.50 x 2.00 mm (CX2520DB) ceramic package and a load capacitance of 8 pF. The frequency stability is ±40 ppm over a temperature range of -25° up to +85°C. The tuning fork crystals are packaged in a 2-pad 2.00 x 1.20 mm (ST2012SB) or 3.20 x 1.50 mm (ST3215SB) housing with a load capacitance of 12.5 pF. The frequency stability is ± 250ppm over a temperature of -25°C up to +85°C. All crystal units are RoHs compliant and ready for 260°C reflow soldering.
