Ultra Low Current KX Series Crystal Oscillator

2.5 x 2.0mm

KX251

CMOS 32.768kHz

2.5 x 2.0mm 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 (< 10µA)

• Very tight temperature stability

• Designed for standard reflow and washing

techniques

• Pb-free and RoHS/Green compliant

Product Description

Pin Functions:

The KX251 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 10µA. The output clock

signal is compatible with LVCMOS/LVTTL logic

levels. The device, available on tape and reel,

is contained in a 2.5 x 2.0mm surface-mount

ceramic package.
