Supply [Broadcom] AFSI-R74C4SB Fiber Optic Modules: 56Gb/s Quad-Channel PAM-4 Linear TIA IC - Transimpedance Amplifier

AFSI-R74C4SB is a 4-channel linear TIA (Transimpedance Amplifier) IC designed for 28-GBaud (56 Gb/s) PAM4 (Pulse Amplitude Modulation) transceiver applications. These Rx ICs amplify four single-ended electrical signals received from the PiN array. An RSSI (Receive Signal Strength Indicator) output pad can be used to monitor received signal strength at the PIN detector.

Key Features Of AFSI-R74C4SB
Four-channel linear TIA for 28 Gbaud/s, operable over 56 Gb/s with 28 Gsymbol/s.
Input overload capability up to 5-dBm OMA, (assuming PIN responsivity 0.59 A/W).
Power consumption: 0.14 W/Ch.
Transimpedance adjustable from 180 to 4.5K.
Less than 4% eyelet compression.
Low input referred noise: 16 pA/√Hz.
Channel control: activation, output amplitude, DC-cancellation.
DC cancellation cutoff and activation (for DC test).
Receive signal strength indicator (RSSI) function available.
Serial bus interface with maskable hardware interrupt.
ADC readback: supply voltages, temperature, RxLIP.
TWS communication ports with 400-KHz max speed.
AFSI-R74C4SB offers no RF equalization
