5 x 3.2 x 2.2mm SMD HCMOS

MB53T 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 MB53T TCXO is packaged in 7 x 5mm, 4 pad ceramic SMD

package. The part has a squarewave (CMOS) output and a stability of

±2.5ppm over the temperature range -30° to +85°C. A 0.01mF

decoupling capacitor is built-in. The part may be specified as a TCXO

or a Voltage-Controlled TCXO (VCTCXO).
