I dont need to search for the PRN sequence since I'm generating it in
the same device, and there is no time lag to speak of (speed of light).
What IC and ciruit do I use to extract this signal.

If there is no time lage, what do you expect to glean from the correlation?

"Yup, it's there!"

Are you using a 2D array such as a CMOS imager and trying to find the
position in the frame?

The speed of light is roughly a nanosecond per foot so detecting distance
with a retroreflector and high data rate light source is very doable. This
distance measurement would require a short skew of the correlator to match
up the precise correlation peak.
