Miniature Crystals Offer High Stability & Low Ageing in Size/Cost Constrained Consumer Applications
Posted: 4th February 2009
IQD Frequency Products has launched a new range of low-cost miniature quartz crystals for use as timing sources in consumer electronics and computing applications. The new CFPX-181 series is available in a range of fundamental frequencies from 16.0MHz to 50MHz.
Housed in a hermetically sealed, four-pad ceramic SMD package measuring just 2.5 x 2.1mm, the CFPX-181 series is suitable for use in set-top boxes and personal video recorders (PVRs), games consoles, smart card readers and a wide variety of computer peripherals and IT equipment with tight space and cost limitations.
For accurate performance at high data transfer rates, the CFPX-181 can be specified to stabilities as good as 10ppm over an operating temperature range from -10° to +60°C. Crystal ageing properties are also excellent at just 1ppm per year (maximum, at +25°C).
"Consumer and ICT devices are being made continually smaller and lower in price, but still have to cope with ever increasing data rates," said IQD's Application Support Manager, Peter Sinclair. "The CFPX-181 is the perfect timing source for systems with oscillator circuitry already embedded into a chipset: a miniscule crystal with cutting-edge performance and stability."
CFPX-181 crystals can be delivered in both bulk-pack and tape-and-reel formats.
