Har nogen arbejdet med SI5340 Clock Generator/osc? (erstatter SI5351?)

Mange radioselvbyggere kender SI5351. Hvem har arbejdet med SI5340? Hvad synes I om SI5340?

New SI5340-based RF Board in development:

Citat: "...
The SI5340 offers rock solid performance from 100 KHz to 250 MHz with LVCMOS outputs (employed by the prototype RF board), dramatically reduced phase noise and jitter, much improved clock symmetry (upon which the performance of Tayloe mixers depends), and much simpler application-level control software (no mucking about with the PLL, Multisynth, or phase at the application level). The new RF board replaces the 5351 with the 5340, and restores true split operation (the SI5340 has four outputs, three of which are used for RX, TX, and CWTx). The most challenging part of the software was the algorithm for setting output frequency, that is, given a desired frequency, find near-optimal numerator and denominator values for the various dividers used within the SI5340.

Just had a look at what the Si5340 is. It will have a place in high performance radios, but it's not going to replace the Si5351 in all applications. It's a much more expensive part; the cheapest version is over $16 in quantity one (the Si5351 is a bit over $2) and doesn't do fractional dividers so its frequency flexibility will be more limited. The least expensive one that does is over $21.

9) The SI5340 has four main versions. Two of these, the Si5340A-D (up to ~1GHz with some holes) and Si5340B-D (up to 350MHz; perfect for this application) do support both fractional and integer divides. The fractional divide feature is what makes the part a good fit.

Måske kommer der en RFzeroNG?:
