Plan for a 50 MHz Analog Output Channel

This note develops a design based on a direct synthesis technique, using a data stream considerably slower than 200 MS/s.

You may download this note in its entirety in PostScript (108K). The PostScript version can be printed on any PostScript printer, or previewed with the Ghostscript suite.

PDF version of the note.

You may download a kit (11K) that allows a complete regeneration of the note, including all computations. This kit is tested on a Linux box with octave and LaTeX installed. Unpack it, and type "make" to get as far as the .dvi and .eps files. Other choices include "make print" and "make web".

You may look at the individual pieces, where all the figures are given in .eps form:

• LaTeX source file
• Figure 1. Notch filter concept.
• Figure 2. Output waveforms.
• Figure 3. Output channel schematic.
• Table 1. 40 MS/s output line strengths.
• Table 2. 80 MS/s output line strengths.
