The MAX3803 is a high-performance differential line equalizer from Maxim Integrated Products. It has a small size of 2mm x 2.5mm and supports 1Gbps to 3.2Gbps transmission speed. It is suitable for backplane interconnect, rack-to-rack interconnect and other applications.
The MAX3803 equalizer automatically compensates for loss in FR4 stripline and twin‑ax cable, extending reach for backplane connections up to 40 in (1 m) and rack‑to‑rack links up to 10 m. It operates from 0 °C to +85 °C, consumes 160 mW at +3.3 V, and supports data rates from 1 Gbps to 3.2 Gbps.
The device is supplied in a 2.5 mm × 2 mm 5 × 4 UCSP chip‑scale package with four perimeter balls. Pin functions include DC‑coupled CML inputs/outputs, termination voltages as low as +1.1 V, and an enable pin for power saving. Recommended layout practices include controlled‑impedance traces, short ground connections, and close decoupling.
