[Lowfer] new chip, of possible interest to lowfer ops

[Art]

Hi Everyone.

I recently learned about a new chip, the SI570 (available from 
www.scilabs.com). It is basically a self contained cmos signal 
generator chip that operates from 10 MHz through 900 MHz. It has some 
outstanding phase noise ratings and could be a much less expensive 
solution than a DDS for those needing frequency agility. It offers 
frequency resolution down to the ppb range and can be divided down to 
lowfer frequencies with a simple digital divider.

Unlike some other low grade programmable oscillators on the market, 
this one is very clean with no spurs and is suitable for receiver 
LO's into the VHF range (low phase noise).

The softrock group is doing group buys and there is a PCB available 
too, the board can be ordered online with paypal.
