You don't need to worry about bandlimiting Phase accumulator based
oscillators. as they are effectivly variable sample rate based. Its only
things with a fixed sample rate (DSPs for example) that bandlimiting becomes
an issue.

yeah, theres a bundle to choose from, try doing a google search for DCO,
technique, schematic and so on..
