Crystals TCXOs  VCXOs  SAW devices and FCXO modulesNDK announced the availability of its COTS line-up of Crystals, TCXOs, VCXOs, SAW devices and FCXO modules. The product offerings are suited for high reliability, demanding environments like defense communications, aerospace, down hole, and maritime applications. The crystals are available in as broad an operating temperature range of -40 to +150C (less demanding temperatures are available) and frequencies up to 50 MHz. They feature high shock & vibration resistance and have proven themselves in on-engine automotive applications for years. They are all SMD with packaging as small as 3.2 mm x 2.5 mm, making them some of the smallest COTS crystals available. According to the company, the world’s smallest COTS, GPS grade TCXO (temperature compensated crystal oscillator) product features a very tight frequency stability of ±0.5 ppm. The NT2016S measures just L=2.0 x W= 1.6 mm and includes an enable/disable function which allows for deactivation of the oscillator circuit thus conserving power which is particularly valuable in battery powered applications. They operate in a -30 to +85C temperature range on as low as 1.8 VD supply voltage. The VCXOs (voltage controlled crystal oscillators) are available in frequencies up to 700 MHz. They have a frequency stability of ±50 ppm and with a frequency control range of ±100 ppm/+1.65 ±1.5 V. They operate in a temperature range of -30 to +85C with a supply voltage of +3.3 VDC providing an LVCMOS, LVPECL, or LVDS output.
