The system supports 4x4 MIMO applications and several commercial standards including cellular, WiMAX, and WLAN and offers [+ or -]1-ns signal sampler synchronization, <1 ns peak-to-peak signal sampler jitter, and <1 degree of peak-to-peak RF-carrier phase jitter.
The LVE-PECL crystal oscillator RFX250 and LVE-PECL voltage-controlled crystal oscillator RFV250 feature phase jitter of < 0.5 ps and a frequency range from 600 MHz to 1.25 GHz.
Operating at 622.08 MHz over a temperature range of minus 40 to plus 85 degrees C, CTS Model 650 surface mount clock oscillators employ a patent-pending technology that provides typical RMS phase jitter of less than 1 pico-second, and excellent frequency stability of plus/minus 15 ppm.

It also accommodates 10-GHz clock and PLL applications and tests multiple differential data channels; isolation of jitter components such as RJ and DJ to get total jitter at [10.sup.-6] and [10.sup.-12]; jitter accumulation; skew; period accuracy; phase jitter to [10.sup.-6] and [10.sup.-12]; and FFT of power spectral density.
With phase jitter at < 0.5 ps and frequencies from 600 MHz to 1.25 GHz, the series is ideal for applications such as SONET, SDH, ATM and WAN.
Given a signal with L(fm) single sideband phase noise characteristics, the phase jitter (in radians) is given by
