The is a quad PCI express equalizer/redriver in 42 pin TQFN package. The MAX4950 PCI Express PCIe quad equalizer/ redriver operate from a single +3.3V supply. This device improves signal integrity at the receiver through programmable input equalization and programmable redrive circuitry. The output circuitry re-establishes deemphasis lost on the board, compensating for circuit board loss. This device permits optimal placement of key PCIe components and longer runs of stripline, microstrip or cable. The MAX4950 contains four identical buffers capable of equalizing differential signals at data rates up to 5GT/s and features electrical idle and receiver detection on each channel. The MAX4950 is ideal for use with PCIe Gen I 2.5GT/s and Gen II 5.0GT/s data rates and features a power-saving mode.
