National used to make one -- MM5230???  I don't recall, but a CRTC
IC is generally a more useful way to do this.  A 6545 can be programmed
to generate pretty much standard NTSC video, interlaced and all.
It also generates all the memory scanning info you should need at
the same time.  I haven't kept up lately, but suspect there are a lot
of CRTC chips that could do similarly
