Video Divisions

logical clock divisions, preset x, y & frame rate divisions, sequencing

video divisions is a high speed digital logic processing module with several complex modes for generating horizontal and vertical bars, and dividing other signals. it is capable of processing signals throughout the video bandwidth. each of the two inputs includes a high speed comparator which converts any input signal into key logic around a threshold of 0.5 volts. as with all modules in the lzx visionary line, the inputs can therefore receive any type of signal, not just binary logic pulses.

please note: this module requires connection to the video sync generator by means of a video sync distribution chain cable which must be purchased separately.

video divisions includes four preset modes and four count modes.

ext mode
in ext mode, the eight outputs represent eight divisions of an input signal put into the clock input. the current count is reset via a pulse at the reset input. when in sq+ count mode, the outputs count one after the other in a ring, so that only 1 output is high at any time. this function is similar to a gate sequencer. in dv+ count mode, the outputs represent binary divisions /2, /4, /8, /16, /32, /64, /128, /256. while in ext mode, the sq- and dv- modes are identical to sq+ and dv+, except that the input clock is blanked so that clock pulses outside the viewable area of the screen are ignored. this is useful for correcting glitches in horizontal patterns.

frm mode
in frm mode, the eight outputs represent divisions of the system's frame rate clock. the count is reset via a pulse at the reset input. when in sq+/sq- count modes, the outputs count one after the other in a ring, so that only 1 output is high at any time. this function is similar to a gate sequencer. in dv+/dv- count mode, the outputs represent binary divisions /2, /4, /8, /16, /32, /64, /128, /256.

x mode
in x mode, the eight outputs produce vertical bars. the clock and reset inputs control a secondary counter which offsets the primary counter, to achieve modulation. when in sq+/sq- count modes, the outputs count one after the other in a ring, so that only 1 output is high at any time. this function is similar to a gate sequencer. in dv+/dv- count mode, the outputs represent binary divisions /2, /4, /8, /16, /32, /64, /128, /256. in sq+/dv+ modes, the secondary counter shifts the vertical bars to the right. in sq-/dv- modes, the secondary counter shifts the vertical bars to the left.

y mode
y mode is identical to x mode, except horizontal instead of vertical bars are produced by the outputs.
