Raltron touts low-jitter VCSO
SEPTEMBER 5, 2008 -- Using a SAW device, the VSO9900A bypasses the many multiplication stages needed to attain a high frequency with standard crystal-based designs and operates directly at frequencies such as 622.08MHz or higher, say company representatives.
SEPTEMBER 5, 2008 -- Raltron Electronics Corp. (search for Raltron Electronics) today introduced its new series VSO9900A voltage-controlled surface acoustical wave (SAW)-based oscillator (VCSO), offering a very low jitter at high frequencies such as 622.08 MHz, say company representatives.
Using a SAW device, the VSO9900A bypasses the many multiplication stages needed to attain a high frequency with standard crystal-based designs and operates directly at frequencies such as 622.08MHz or higher.
According to the company, the VSO9900A series is particularly suitable for applications like SONET/SDH, base stations, high-speed data transfer, optical transmission, and all kinds of phase locked loops (PLLs). The family has been designed for a frequency range from 400 MHz to 1 GHz with particular emphasis on typical frequencies used in the optical transmission domain (622.08 MHz, 644.531 MHz, 669.327 MHz, etc.).
The new line of VCSOs is offered in a compact 5- x 7- x 2.5-mm package, producing a jitter as low as 0.100 ps-rms within a bandwidth of 12 KHz to 20 MHz; phase noise of -150 dBc /Hz at 10 KHz offset from carrier; and an absolute pull range (APR) of ±100 ppm, claims the company. The VSO9900A series operates on a supply voltage of 3.3 V and features LVDS or LVPECL complementary outputs as well as an enable/disable function.
Priced at $ 28.00/each for 1,000 pieces, the VSO9900A is available in eight weeks ARO for production quantities. Samples are available in 2-4 weeks ARO.
