New Family of Temperature Compensated Crystal Oscillators from Pericom Semiconductor

Pericom Semiconductor Corporation, a leading supplier of high-speed connectivity, signal-conditioning and timing solutions, today introduced a new product family of Temperature Compensated Crystal Oscillators (TCXO), many with added Voltage Controlled option (VCTCXO) and all designed to bring excellent performance, small size, low power, and value to mobility platforms such as smart phones, GPS, wireless modules, and portable industrial and medical equipment, as well as more traditional telecommunications and automotive applications.

"Our new TCXO family allows mobile platform designers to have excellent frequency and voltage stability performance over a very wide temperature range while still meeting their cost targets," said Steve Wang, Pericom marketing director for timing products. "Being fully vertically integrated allows us to optimize and match our quartz based product design and manufacturing process to customer needs, especially features that enable smooth integration into mobile platform designs."

Pericom TCXO products offer excellent frequency stability from ±0.5-5.0 ppm over the industrial temperature range of -40°C to +85°C. Typical support frequency ranges from a few MHz to a maximum 40 MHz to cover almost all application needs. Supply voltage options cover 1.8V to 3.3V. The new product family includes many frequency options available in both TCXO and VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) options in which the VCTCXO option is voltage-controlled from an external processor.

Aimed at space critical mobile platforms, Pericom's new TCXO/VCTCXO family supports both standard 3225 (3.2mm x 2.5mm) and 2520 (2.5mm x 2.0mm) small package sizes.

Annual TCXO unit shipments will reach 1100 million (1.1B) in 2013, driven by siginificant growth of mainly smart phone based GPS applications. 3225 and 2520 package sizes account for 80% of total TCXO volume, with the 2520 becoming the mainstream package size through 2016.
