Frequency Quartz Crystal Unit
Kyocera Corporation announces that its subsidiary Kyocera Kinseki will ship the CX3225SB, a miniature low frequency quartz crystal unit which oscillates in the 4 MHz frequency range. The CX3225SB provides stable frequency sources for applications that require compact size and power savings, such as portable DVDs, hand-held game-players, PDAs and cellular handsets. Kyocera Kinseki divided higher frequencies, such as 16 MHz, using an IC, to obtain 4 MHz. If small crystal units oscillate at 4 MHz directly, the dividing process can be omitted. The CX3225SB reduces the power consumption of the overall device by approximately 30%. In addition, the CX3225SB complies with the RoHS Directive, the European Union's Restriction of Certain Hazardous Substances, and is compatible with the reflow profile of lead-free soldering.
