SD-SDI 270MHz, then there is the HD-SDI.
Brooke, the 77.503KHz you mention for the DCF77: are you sure the IF is
3KHz? 77.503KHz is 77.5KHz + 3Hz...

13.5 and 27 MHz are usually associated with digital video. SD video with
720 x 576 has a pixel clock of 13.5 MHz, and the corresponding SDI bit
clock is 270 MHz.

An: Discussion of precise time and frequency measurement
Betreff: [time-nuts] Why these Crystal Frequencies?
Hi Pete:
Maybe you can shed some light on the common xtal frequencies table where
there's no explanation given?
http://www.prc68.com/I/pdf/Crystal_Freq.pdf
An answer is not it's an "even" frequency or "it's an even binary
frequency. That's true for most of these and the factors are part of the
table above.
The question is why do they exist?
such as:
32.0 kHz
40.0
75.0
76.79
76.8
76.81
96.0
3.072 MHz
4.0
4.096
5.0
6.0
7.3729
8.0
8.192
9.8304
10.0
11.0
11.0592
11.2896
12.0
12.288
12.352
13.5
14.31818
15.36
16.0
16.384
17.734475
18.0
18.432
19.6608
19.44
22.1184
24.0
24.567

It's exactly 52 times the 1.2288MHz reference that IS95/CDMA2K uses -
this may be a coincidence, but I somehow doubt it.

I have been watching this thread and may have missed something. My
questions: What is the purpose of the outboard OCXO VECTRON
63.8976Mhz? What model number does this RB most closely resemble?
