DATASHEET 32.768 KHZ CLOCK OSCILLATOR MK3200 Description Features The MK3200 is IDTs lowest cost, low power clock oscillator Packaged in 8-pin SOIC or 8-pin MSOP (3.00 mm body) that generates a low power 32.768 kHz output from an Pb (lead) free package inexpensive 32.768 kHz crystal. This part includes a power Operates from 2.5 V to 5 V down pin and allows you to tri-state the output clock for in-circuit testing. Consumes only 3.5 A in normal operation Accepts an inexpensive 32.768 kHz crystal input IDT manufactures the largest variety of clock synthesizers for all applications. If more clock outputs are needed, Offers power down mode including MHz frequencies, see the MK32xx family of parts. Includes an Output Enable pin to tri-state the output for Consult IDT to eliminate VCXOs, crystals and oscillators in-circuit testing from your board. Advanced, low power, sub-micron CMOS process For other 32.768 kHz-based clocks with MHz outputs, please consult IDT Industrial temperature version available Block Diagram VDD Power Down X1 Crystal 32.768 kHz 32.768 kHz Crystal Oscillator Clock X2 GND OE IDT 32.768 KHZ CLOCK OSCILLATOR 1 MK3200 REV H 073012MK3200 32.768 KHZ CLOCK OSCILLATOR 32 KHZ OSCILLATOR Pin Assignment Power Down Select Table PD 32.768k Oscillator X1 1 8 X2 0 On On VDD 2 7 GND 1Low Off GND 3 6 PD 32.768k 4 5 OE Output Enable Select Table 8-pin (150 mil) SOIC or OE 32.768k Oscillator 8-pin MSOP (3.00 mm body) 0 Tri state (Hi-Z) On 1On On 0 = connect directly to GND. 1 = connect directly to VDD.
