Fig. 1 Functional Block Diagram The ASNT6103-KMF SiGe IC shown in Fig. 1 is a PAM4 encoder with built-in 4-tap pre-emphasis in each of the two input data channels. Each of the two differential input NRZ data streams is processed by a 4-tap shift register. Both 4-bit shift registers are activated by the same internal … Continue reading ASNT6103-KMF
