SiTime's SiT9121 and SiT9122 MEMS-based differential oscillators feature a high stability of up to [+ or -]10 ppm and 500 fs of integrated RMS phase jitter
. They can serve in routers, servers, SATA / SAS / Fibre Channel HBAs, wireless base stations and 10G Ethernet switches.
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.
: Phase Jitter
Modulation; an RFID technology that can quickly and accurately identify large volumes of tagged items stacked or stored in any physical orientation.
Features include low phase noise of -160 dB relative to the carrier per hertz (dBc/Hz), typical RMS phase jitter
of 0.5 ps, and a low bit error rate.
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.
Due to its MEMS technology design, phase jitter
is low being typically 0.7 ps at 200 MHz.
Given a signal with L(fm) single sideband phase noise characteristics, the phase jitter
(in radians) is given by
