7 x 5 x 2.3mm SMD HCMOS
MB572T TCXO
DESCRIPTION
Quick turnaround production
Low Jitter: 70ps peak to peak (typical)
Low phase noise: -114dBc at1kHz offset (133MHz)
Custom frequencies are easily configured
Supply voltages 2.8V, 3.0V or 3.3VDC
TCXO or VCTCXOs CMOS square wave output
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.
