The MXL-CD-PHY-UNIV-T-22ULP is a high-frequency, low-power, low-cost, source-synchronous, physical Layer supporting the MIPI Alliance Specification for D-PHY v2.5 and C-PHY v2.0 The PHY can be configured as a MIPI Master or MIPI Slave supporting camera interface CSI-2 and display interface DSI/DSI-2. The PHY supports mobile, IoT, virtual reality, and automotive applications.
Mixel’s MIPI C-PHY v2.0 supports a speed of 4.5 Gsps per trio, an equivalent data rate of 10.26 Gbps/trio. In D-PHY mode, the IP supports speeds up to 4.5 Gbps per lane and complies with the MIPI D-PHY v2.5 specification. With up to three trios in C-PHY and up to four lanes in D-PHY, the combo IP reaches an aggregate bandwidth of 30.78 Gbps and 18Gbps in their respective modes.
The Mixel MIPI C-PHY/D-PHY Combo IP includes many new features to both the D-PHY and C-PHY that was not available in previous versions of the specifications, namely Spread Spectrum Clocking (SSC), transmit equalization (de-emphasis), and receiver ISI calibration. It also supports new power saving functionality such as HS-TX reduced swing modes and the HS-RX unterminated mode. The new Alternate LP Mode, suitable for IoT applications with long channels, is also supported, enabling Fast Bus Turnaround that boosts transmission bandwidth in the reverse direction of the MIPI link. The ALP Mode is central to the CSI-2 Unified Serial Link feature that reduces number of interface wires and helps to natively support longer reach. The combo PHY IP not only shares the serial interface pins, but Mixel’s implementation also reuses all the MIPI D-PHY functional blocks for the MIPI C-PHY, minimizing area and leakage power.
