NDK TCXOs target in-car navigation

Nihon Dempa Kogyo Co. is offering GPS grade temperature controlled crystal oscillators (TCXOs) that measure 2.5 x 2.0mm, are no more than 0.8mm high, and weigh 0.013g.

NDK’s NT2520SA surface mount device series exhibits ±0.5 ppm frequency stability over a -30 to +85°C temperature range. The devices are available in frequencies of 13, 16.368, 16.369, 16.8, 19.2, 24.5535, 26, 27.456, and 38.4MHz with supply voltages ranging from +2.4 to 3.2VDC ±0.1 V. They draw 1.5mA max with an output level of 0.8 V (peak-to-peak) minimum. Aging characteristics are ±1 ppm maximum per year.

Target applications include in-car navigation, vehicle tracking, and emergency road support systems. The devices are priced at approximately $1.65 in 10,000-piece quantities.
