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 inter-
symbol interference. The MAX3804 can extend the practi-
cal 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 equal-
ization for 10.7Gbps signals is typically 24ps
maximum path length.
The MAX3804 is ideal for 10Gbps chip-to-chip serial
interconnections on inexpensive FR-4 material. Its
3mm
routing flexibility. It has separate V
internal logic and current-mode logic (CML) I/O. This
allows the CML input and output to be referenced to iso-
lated supplies, providing independent DC-coupled inter-
facing to 1.8V, 2.5V, or 3.3V ICs. Eight discrete levels of
input equalization can be selected through a digital con-
trol 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 per-
formance over a wide range of data rates and formats.
