Abstract
Phase compensation in an I/O (input/output) circuit includes a triangular control contour with a simplified generation circuit. A linear control circuit can generate a digital N-bit linear count, and route the least significant M bits [(M−1):0] for linear control for fine delay mixing of a phase compensation loop and the most significant (N−M) bits [(N−1):M] for linear control for coarse control of a delay chain for the phase compensation loop. Prior to decoding the least significant M bits for fine delay mixing, the control circuit performs a bitwise XOR (exclusive OR) of bit M with each of bits [(M−1):0] to generate M linear control bits as the linear control for fine delay mixing. The M linear control bits generate a linear control count having a triangular contour, where the linear control count continuously, repeatedly counts from 0 to (2−1) to 0.
