Abstract (en)

[origin: EP0778517A2] A system for encoding control data onto a clock signal includes at least one clock cycle in the clock signal; a first transition in the at least one clock cycle, the first transition is from a first voltage level to a second voltage level, the first transition is in a first location in the at least one clock cycle; a second transition in the at least one clock cycle, the second transition is from the second voltage level to the first voltage level, the second transition has a variable location in the clock cycle; and an encoder circuit for positioning the second transition in the variable location in response to the control data. <IMAGE>
