EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE EURO QUARTZ 11.4 x 9.6 x 2.5mm 4 pad SMD HCMOS MB42T 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 MB42T 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.
