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)

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 data transfer quality. This is new concept that UHS-I doesn’t have. Impedance Control No Yes
Signal Amplitude 1.8V 400mV differential Small amplitude in UHS-II have more sensitivity against loss and noise from system.
Noise/Jitter specification Simple Timing budget between clock and data
Complex Jitter specification for serial data transmission
Noise/Jitter spec for serial interface is not simple. Some knowledge about serial link will be required to understand it.
SD Card Connector Electrically Sensitive but no electrical spec
Electrically sensitive and return loss is defined
Impedance mismatch in SD connector will affect whole UHS-II channel characteristics.

Challenge in UHS-II Electrical
UHS-II Speed (1.56Gbps)
UHS-I Speed (200MHz)
*Waveforms are shown in same time/voltage scale.
UHS-II signal is much faster and smaller amplitude.
