MB572T - OUTLINES AND DIMENSIONS
DESCRIPTION
The MB572T TCXO is packaged in 7 x 5mm, 4 pad ceramic SMD
package. The part has a squarewave (CMOS) output and a tight
stability over temperature. The part may be specified as a TCXO or a
Voltage-Controlled TCXO (VCTCXO). A 0.01mF decoupling capacitor
is built-in.
