Ti CD4046BE - CMOS PLL / Oscillator : weekend die-shot

We used to think that 4000-series or 7400-series standard logic are all relatively simple ICs. Ti CD4046BE is probably the most complex of these - It's a PLL with internal VCO and even zener voltage reference for external voltage regulator. It could still be useful today, if you're fine with it's 1.4Mhz frequency limit.

Die size 2271x2007 µm.
