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 ✕ 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.
