CMG1

EZ-PD™ CMG1 Datasheet USB Type-C EMCA Controller General Description EZ-PD™ CMG1 is a dedicated USB Type-C EMCA controller that complies with the USB Type-C and Power Delivery (PD) standards for Electronically Marked Type-C Thunderbolt and non-Thunderbolt passive cable applications. EZ-PD CMG1 integrates a complete Type-C transceiver including the RA termination resistors on the VCONN pins and VBUS short circuit protection on both VCONN and CC pins. CMG1 also includes 40 bytes of storage for configuration of vendor-, device-, and cable-specific configuration data. EZ-PD CMG1 is targeted for passive EMCA implementations with either one or two e-marker chips on the cable. Features Type-C Support and USB-PD Support ■ Supports USB PD3.0 spec and USB Type-C spec version 1.3 (Including support for the revised minimum VCONN operating voltage of 3 V) ■ Integrated high-voltage protection on CC, VCONN1, and VCONN2 pins to protect against accidental shorts to the VBUS pin on the Type-C connector ■ 40-byte storage programmable over Type-C interface for storing vendor-, device-, and cable-specific configuration data ■ Termination resistor RA on VCONN1 and VCONN2 ■ Supports RA weakening to reduce power consumption ■ Supports electronically marked passive cable implementations with one or two controllers Clocks and Oscillators ■ Integrated oscillator eliminating the need for external clock Power ■ 2.7 V to 5.5 V operation ■ Sleep: 1.7 mA System-Level ESD Protection ■ On CC, VCONN1, and ...
