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.

UHS-II Test Guideline


UHS-II Electrical Test

Transmitter Test for UHS-II (Demo) -Loopback Mode is defined in the standard spec for TX test. -The oscilloscope and Pulse Pattern generator will be used for this test.



Receiver Test for UHS-II -Loopback Test Mode -Inject Jitter Stress on Input data to test RX jitter tolerance



Impedance Test -Network Analyzer will be used to test impedance characteristics -This test has to include all system components such as PCB, UHS-II socket
