The PLXO series of phase-locked crystal oscillators from EM Research is now available with significantly improved performance and smaller size. With the option of a surface-mount or connectorized package, PLXO offers several outputs, including sine 7 dBm, 10 dBm, CMOS and PECL.


The new smaller-sized surface-mount package (0.9” x 0.9” x 0.25”) also features an exceptional 15 dB improvement in phase noise characteristics (<-140 dBc/Hz at 1 kHz typical) and enhanced spurious response (<-65 dBc). The PLXO is available in fixed frequencies between 5 and 420 MHz with a lock range of ±5 ppm. Applications include: DDS clocks, DAC and ADC clocks, Fibre Channel Ethernet, SAS/SATA, SONET/SDH and receiver LOs.
