According to Table 6 of the datasheet [1], the adaptive equalizer (AEQ) can compensate for different amounts of cable attenuation depending on the Nyquist frequency. I have two questions regarding my understanding of this equalizer:
1. Is the stated attenuation to be read as in addition to the FPD link's loss? For example, the datasheet states up to 12dB are compensated at 1.64GHz Nyquist. On the other hand, the acceptable channel loss can be estimated based on Tx voltage swing (e.g. 1V) and Rx voltage swing requirements (e.g. 0.1V): 0.1V/1V = 0.1 --> -20dB channel loss that would be acceptable at Nyquist without equalization. Thus, including the benefit of equalization would lead to a total of 32dB channel loss. Is this correct?
2. Is there any information on the topology of the equalizer for ease of understanding? Does a continuous time linear equalizer (CTLE), i.e. analogue circuit, resemble its main features?
