system-level and circuit-level verification of a PHY link as well as system performance optimization in respective of power, reliability and adaptability in high-speed communication systems.The PHY is mainly composed of clock data recovery (CDR), equalizers (EQs) and high- speed I/O drivers. Sy...
The interface negotiates the fastest data transmission speed supported by the serially connected components. Link parameters associated with the negotiated data transmission speed are calibrated and implemented in a Phy layer of the interface before data is transmitted across the...
Link parameters associated with the negociated data transmission speed are cablirated and implemented in a Physical layer of the interface data before data is transmitted accross the interface. The cablirated link parameters include signal settings for amplitude, pre-emphasis, equalization and timing....
