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.ApplicationsHigh-Speed Signal DistributionOC-192 and 10Gb Ethernet Serial ModulesOC-192 and 10Gb Ethernet Switches and Routers
