Oscillator has ultra-high frequency stability

The SiT9102 has been introduced along with the SiT9103 and SiT9104, 3-PLL programmable clock generators with an embedded MEMS resonator.

Quartz oscillator manufacturers typically offer frequency stability between 25 and 100 PPM.

Sitime's 10 PPM solutions increase the availability of such high-stability clock oscillators.

This technology is being offered on the differential output oscillator SiT9102 and the programmable oscillator SiT8102.

The improved frequency stability enhances the system timing margin and long-term reliability by reducing the impact of random low-frequency noise generated by transformers, power lines and lighting.

The SiT9102 is a programmable, differential output MEMS oscillator that can operate at frequencies up to 800MHz.

It is programmable for three common differential standards: LVPECL (2.25V to 3.63V), LVDS (2.25V to 3.63V) and CML (1.8V and 2.25V to 3.63V).

It is also programmable for any frequency between 10 and 220MHz, as well as popular frequencies in the 220MHz and 800MHz range.

The SiT9102 offers random RMS phase jitter of less than 1 picosecond.

It is available in two industry-standard six-pin packages: 5.0 x 3.2 x 0.85mm and 7.0 x 5.0 x 0.85mm.

Typical applications for the SiT9102 include servers, routers, Raid controllers, fibre channel, PCI-Express, Gigabit Ethernet and optical networking equipment.

The SiT9102's programmability allows delivery of samples in 24 to 48 hours and production quantities in two to three weeks.
