SD Association. All rights reserved. SD Association 13 UHS-II Specification Overview 1. High speed I/F up to 312MB/s @Gen 1 (Ver1.01) Two pairs of differential signal up to 156MB/s at each lane, considering ease of Host design 312MB/s can be achieved by Half Duplex mode (optional) Target of Gen 2 is up to 624MB/s 2. Continuously-variable data rate covering Covering from 39MB/s to 312MB/s @Gen 1 Host can select appropriate clock frequency from 26 MHz to 52 MHz 3. Legacy SD-compatibility UHS-II Card shall also support Legacy SD I/F for fully backward compatibility Encapsulation of Legacy SD Format for reusability of existing resource 4. Low voltage, low power consumption and low EMI Considering availability for mobile equipment Various power saving methods are introduced (Hibernate Mode)

SD Association 15 Challenge in UHS-II Electrical UHS-I UHS-II Notes Data Rate 104MB/s 312MB/s Achieved 3 times faster Synchronous Clock Yes, direct data sample No, PLL/CDR based data sampling Huge technology gap to serial interface from parallel. Termination No Yes Impedance control is the key for good Impedance Control No Yes data transfer quality. This is new concept that UHS-I doesn t have. Signal Amplitude 1.8V 400mV differential Small amplitude in UHS-II have more sensitivity against loss and noise from system. Noise/Jitter specification SD Card Connector Simple Timing budget between clock and data Electrically Sensitive but no electrical spec Complex Jitter specification for serial data transmission Electrically sensitive and return loss is defined Noise/Jitter spec for serial interface is not simple. Some knowledge about serial link will be required to understand it. Impedance mismatch in SD connector will affect whole UHS-II channel characteristics.
