Fig. 1. Functional Block Diagram The ASNT8121-KMC SiGe IC shown in Fig. 1 provides a differential phase error signal perp/pern that indicates the phase difference between the data dp/dn bit transitions and the edges of the input clock cp/cn. The input data spectrum can be corrected by the equalizer EQ with a frequency response adjustable … Continue reading ASNT8121-KMC
