5x7mm

Precision TCXO

Model D75A

Description:

Features:

•ꢀ3.3ꢀVdcꢀOperation

The Connor-Winﬁeld’s D75A is a 5x7mm

Surface Mount Temperature Compensated

Crystal Controlled Oscillator (TCXO) with a

Tri-State LVCMOS output. Through the use

of Analog Temperature Compensation, the

D75A is capable of holding sub 1-ppm sta-

bilities over the 0 to 70°C temperature range.

The D75A meets STRATUM 3 requirements.
