5.0V Surface Mount

Crystal Clock Oscillator

HSM9

Features:

The Connor-Winfield models HSM915,

HSM925, HSM935, and HSM945 are 7.5mm x

5mm, 5.0V HCMOS, Surface Mount, Fixed

Frequency Crystal Oscillators (XO) designed for

use in all applications requiring precision clocks.

This oscillator features low stand-by current

(10uA) when the output is disabled. The RoHS

compliant, surface mount package is designed

for high-density mounting and is optimum for

mass production.
