Discera Ships Sicon MEMS Oscillator

Discera announced the production availability of its DSC3001 PureSilicon oscillator for mobile, video, and audio applications. The device is available in frequencies up to 150 MHz and temperature ranges up to 105 degrees Celsius with shock resistance up to 30,000 G.

Discera said its DSC3001 series of oscillators is available in both low power and high precision configurations that consume as little as 3mA of power and deliver higher frequency stability over wider temperature ranges for better performance than other crystal or silicon based products.

Key features include:

  • 1.6 mm x 1.2 mm x 0.5 mm footprint

  • Output frequency support from 1 to 150 MHz

  • Frequency stabilities of 10, 25, 50 ppm across temperature and voltage

  • Operating temperature range up to 105 degrees Celsius

  • Supply current as low as 15uA standby, 3mA active from 1.7 to 3.6V

  • Fast startup time of 1.0 millisecond

  • MIL-STD883 shock and vibration tolerant to 30,000 G

  • AEC-Q100 qualification for automobile applications

  • Lead-free and RoHS compliant

Symmetricom Intros Small Cell Synchronization Solutions

Symmetricom introduced new embedded timing and synchronization solutions for residential and enterprise small cells.

Two versions are offered: the SCr (residential) and SCe (enterprise) SoftClocks, both of which support multiple timing protocols including IEEE 1588 (PTP), network time protocol (NTP) and softGPS. Both have been integrated and proven with leading processors, system software, and oscillators from prominent vendors such as Broadcom, Mindspeed, Qualcomm Atheros, Node-H, and Rakon.

Symmetricom said synchronization of small cells along with macro base stations is crucial to maintaining seamless end-user experience. Its software based SoftClock offerings allow small cell designers to execute a single base design with options to integrate one or more synchronization protocols for deployment in varied network topologies. This means multiple types of backhaul and quality of service can be supported.
