... Combined with an on-chip reference delay (to offset the inherent or “step zero” delay of the device) clock phase can now be varied over the full 0-360 degree range. 8-Bit Programmable Timing Element PIN ASSIGNMENT Q/P0 3 CLK/ GND 8 DS1023 300-mil DIP DS1023S 300-mil SOIC PIN DESCRIPTION IN P0/Q P1/CLK P2 GND OUT/ OUT REF/PWM / DS1023 V 16 ...
