FREQUENCY PRODUCTS CRYSTALS Custom Crystals ATC Series CTS Reeves Features: Frequency Range 12 to 75 MHz Surface Mount Ceramic Package Very Low Profile Tape and Reel loading standard CLOCKS * * * * VCXOs This surface mount low profile package offers exceptionally low volume with only 1.3 mm height requirement, perfect for dense layouts or low headroom. The AT-Cut device has the same favorable temperature characteristics as the MP or ATS parts, but with a fraction of the volume, ideal for PCMCIA applications or other space-premium designs.
