1:2 de-mux USB-C Retimer
The MCDP6200 is a low power USB 3.2 x1 retimer with an integrated USB Type-C switch targeted for desktop / mobile PC motherboard-down and USB Type-C device application.
The USB 3.2 x1 retimer supports both SuperSpeed (SS) bit rate (5 Gbps), and SuperSpeedPlus (SSP) data rate (10 Gbps). The USB 3.2 x1 retimer includes the link layer function and LTSSM and RTSSM to participate in the link training. The MCDP6200 supports SS mode with a BLR (Bit-Level Retimer) and SSP mode with a SRIS (Separate Reference clock Independent SSC). The MCDP6200 supports link power management with Ux entry and exits in both SS and SSP modes. In addition, the MCDP6200 supports the link state and link quality maintenance, compensates the clock offset between the downstream port and the upstream port, detects errors, and corrects single symbol errors in framing order sets, single bit block header errors, and single or double-bit SKP symbol errors in SSP mode. It also supports spread spectrum clocking (SSC) to minimize EMI and the low frequency periodic signalling (LFPS). The transmitter employs 3-tap FIR-based transmitter equalizer for SSP operation and fixed transmitter equalizer ranging from 3 dB to 4 dB for SS operation. The receiver employs an adaptive Continuous Time Linear Equalizer (CTLE) and a Decision Feedback Equalizer (DFE). Both the transmitter equalizer and the receiver equalizer are configurable through the TWI register. Proper settings to comply with USB 3.2 electrical requirements are provided by default.
The MCDP6200 operating mode can be configured through the DIS_N and P_POL pins. It can be optionally configured through TWI by enabling the feature through TWI. These interfaces can be controlled from an external Power Delivery (PD) controller or microcontroller to set the plug orientation and the pin mapping of the USB Type-C. The MCDP6200 operates at 1.8 V and 1.2 V.
