Oops, I wasn't paying attention when I looked at the GP30 info - like
Maxim, Acam has gone down the 'more integration' route and buried the
actual TDC under a heap of other stuff, which does rather limit its
usefulness. (data sheets have appeared for it now)
Oh well, nice idea while it lasted.
There´s an entire programable CPU inside it... amazing.

Is this just a function of the ring oscillator
duty cycle being much smaller?
There has been some development on how to do ring oscillators for
TDC applications in recent years. Driven to a large part by the need

Hi
The spec is similar with TDC-GP22. In double-res mode, the
resolution is 45ps, the stdev is 35ps. This unit is 55ps and
35ps. Not sure when the sample chip is ready. The TSSOP package is
much more friendly to homebrew guys.
Indeed this looks like quite an

Hi,

and no extra TDC is

Unfortunately it doesn't look like you can directly access
In case anyone is interested, the full data sheet is on the TI site
now, although I didn't see any actual IC's yet other than the ones in
the eval boards.

Hi Angus:
Do you know if they have an IR pulse front end which would be more interesting
than the ultrasonic front end?
