MAX3804

12.5Gbps Settable Receive Equalizer

Industry's First 12.5Gbps Equalizer Extends Reach to 30in of FR4 in Serial Communications


Please check latest availability status for a specific part variant.

Description

The MAX3804 driver with integrated analog equalizer compensates up to 20dB of loss at 5GHz. It is designed to ensure PC board signal integrity up to 12.5Gbps, where frequency-dependent skin effect and dielectric losses typically produce unacceptable amounts of intersymbol interference. The MAX3804 can extend the practical chip-to-chip transmission distance for 10Gbps NRZ serial data up to 30in (0.75m) on FR-4, and it significantly decreases deterministic jitter. Residual jitter after equalization for 10.7Gbps signals is typically 24psP-P on the maximum path length.

The MAX3804 is ideal for 10Gbps chip-to-chip serial interconnections on inexpensive FR-4 material. Its 3mm x 3mm package affords optimal placement and routing flexibility. It has separate VCC connections for internal logic and current-mode logic (CML) I/O. This allows the CML input and output to be referenced to isolated supplies, providing independent DC-coupled interfacing to 1.8V, 2.5V, or 3.3V ICs. Eight discrete levels of input equalization can be selected through a digital control input, enabling the equalizer to be matched to a range of transmission line path loss. When correctly set to match the path loss, the MAX3804 provides optimal performance over a wide range of data rates and formats.
