Ultra Low Current KX Series Crystal Oscillator
2.0 x 1.6mm
KX201
CMOS 32.768kHz
2.0 x 1.6mm Ceramic SMD
Package: (Scale: none; Dimensions are in mm)
Product Features
Recommended Land Pattern:
• AT Cut 32.768 kHz XO
• CMOS compatible logic levels
• Ultra low active current (< 30µA)
• Very tight temperature stability
• Designed for standard reflow and washing
techniques
• Pb-free and RoHS/Green compliant
Product Description
Pin Functions:
The KX201 Series real time clock oscillator
achieves superb stability over a broad range
of operating conditions. It utilizes Pericom
proprietary technology to achieve ultra low
current less than 30µA. The output clock
signal is compatible with LVCMOS/LVTTL logic
levels. The device, available on tape and reel,
is contained in a 2.0 x 1.6mm surface-mount
ceramic package.
