[time-nuts] Simple PLL chips, gone ?

[Nick Foster]

If you're thinking about using a CPLD to load registers in a PLL chip, why not just implement the PLL on the CPLD? After all, if you're looking for simpler-is-better, there's not much on a dedicated PLL chip that you can't easily replicate in CPLD with some care and attention paid to layout.
