Multi-channel transimpedance amplifier for PIN photodiodes with automatic gain control, DC offset cancellation, RSSI and linear output for PAM4 receivers.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
