[sdiy] overclocking BBDs

[scottnoanh at peoplepc.com]

Hi JH,

Seems that a lot of manufacturers routinely overclocked BBD's in flangers.
Look at the A/DA flanger - on the MN3010 version they overclocked the
bejesus out of that one at, what, 750 kHz?.  AFAIK, a lot of those flangers
are alive and kicking to this day.

I've heard tell the Modcan flanger is one overclocked son of a gun, around 1
MHz if what I've read is true.

I've clocked MN3207's close to 1 MHz without destroying the chip, or even
feeling any appreciable warmth from it.  I have a feeling the clock specs on
the Panasonic parts were just a reflection of what their clock ICs could
handle with max capacitive load and no buffering.

Cheers,
Scott
