Abstract
Circuits for die-to-die clock distribution are provided. A system includes a transmit clock tree on a first die and a receive clock tree on a second die. The transmit clock tree and the receive clock tree are the same, or very nearly the same, so that the insertion delay for a given bit on the transmit clock tree is the same as an insertion delay for a bit corresponding to the given bit on the receive clock tree. While there may be clock skew from bit-to-bit within the same clock tree, corresponding bits on the different die experience the same clock insertion delays.
