Abracon has unleashed its AST3TQ series of precision temperature compensated crystal oscillators. According to the company, TCXOs are available from 10-40MHz carrier frequencies with LVCMOS output, offering ±500ppb frequency stability over -55°C to 95°C.

"These devices comply with Stratum-III stability of < ±4.60ppm all inclusive error over a 20-year product life. Temperature stability options include ±100ppb over -40°C to 85°C, ±280ppb over -50°C to 90°C and ±500ppb over -55°C to 95°C operating temperature ranges. With maximum current drain of 10mA @ 40MHz, these devices offer OCXO level accuracy over a wide operating temperature range, with minimal power consumption," said Syed Raza, director of engineering at Abracon.

Potential applications for these solutions include: COTS military radios & other communication hardware, WiMax, LTE, BTS, CATV, LAN, LMDS, GPS tracking with hold-over accuracy, test & measurement equipment, and point-to-point communication networks.

Key features of the devices include standard available frequencies of 10, 12.80, 19.20, 20, 25, 26, 30.72, 38.40 and 40MHz; standard LVCMOS output; and excellent phase noise, harmonics and spurious content, stated the company. Additionally, Abracon said the TCXOs offer typical RMS jitter of 400fs @ 40MHz carrier and 1ps @ 10MHz carrier over 12kHz to 20MHz BW.

The AST3TQ series will be available through Abracon's global distribution partners by February 2014.
