DisplayPort 1.4a Retimer


The MCDP6150 is a low power DisplayPort1.4a retimer targeted for high-end audio video applications. The MCDP6150 supports 1.62 Gbps, 2.7 Gbps, 5.4 Gbps, and 8.1 Gbps data rates.

The DP1.4a repeater implements AUX_CH snooping function of DPCD addresses defined in the standard as well as the LT-tunable PHY Repeater DPCD registers.

The transmitter employs TXEQ, which adjusts its pre-emphasis level according to either the AUX_CH transaction during the link training or the Two Wire Interface (TWI). The receiver employs a fully adaptive Continuous Time Linear Equalizer (CTLE) and Decision Feedback Equalizer (DFE). The transmitter parameters to support the amplitude level and the pre-emphasis level defined in DP 1.4a standard are provided in default. The transmitter configuration can be also customized to extend the media length such as PCB trace and the cable.

The MCDP6000 implements sophisticated and powerful monitor functions for troubleshooting on PHY and link layer, too.
