摘要
A programmable logic device (“PLD”) includes high-speed serial interface (“HSSI”) circuitry. The HSSI circuitry includes clock signal circuitry that allows various components of the HSSI circuitry to be clocked in different ways to facilitate use of the HSSI circuitry to support a number of different communication protocols. Some of the HSSI clock signals may be routed through the clock distribution network of the associated PLD logic circuitry. The HSSI circuitry may include phase compensation buffer circuitry to compensate for possible phase differences across the interface between the HSSI circuitry and the associated PLD logic circuitry.
