The MK3200 is IDT's lowest cost, low power clock oscillator that generates a low power 32.768 kHz output from an inexpensive 32.768 kHz crystal. This part includes a power down pin and allows you to tri state the output clock for in-circuit testing. IDT manufactures the largest variety of clock synthesizers for all applications. If more clock outputs are needed, including MHz frequencies, see the MK32xx family of parts. Consult IDT to eliminate VCXOs, crystals and oscillators from your board.
