Hi everybody:
I need to take an input clock signal and reproduce a phase locked,
identical frequency output signal. The problem is that the input
signal is 30 - 50 MHz. Now the other problem: the PLL must acheive
lock in under 30 - 35us. Do y'all have any recommendations for PLL ICs
that will work with these specifications?
TI has the most promising ICs, but the lock times might be to long. I
have contacted TI to see if they can give me a better estimate using my
freq. ranges, but thought I would ask around for other IC
recommendations in the meantime.
The two TI ICs are:
1.) http://focus.ti.com/lit/ds/symlink/sn65lvds150.pdf
2.) http://focus.ti.com/lit/ds/symlink/tlc2932.pdf
Another question that I had was this: some of the Philips PLL don't
have an upper freq. limit on their VCO, how is this possible?
Specifically HEF4046B.
Thanks in advance,
Austin McElroy
