12.5Gbps Settable Receive Equalizer
General 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 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
3mm package affords optimal placement and
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.
