9 / 20 page Technical Note 9/19 BU7963GUW www.rohm.com 2010.04 - Rev.A © 2010 ROHM Co., Ltd. All rights reserved. ● Power Modes BU7963GUW has three power modes. 1) Shutdown Mode BU7963GUW goes to Shutdown Mode when XSD = ‘L’. All logic circuits are initialized in the Shutdown Mode. All high-speed signaling channels are disabled, and the outputs keep Hi-Z status. 2)Standby Mode BU7963GUW goes to Standby Mode when XSD = ‘H’ and PCLK is not provided. All high-speed signaling channel outputs keep Hi-Z status. BU7963GUW is monitoring whether PCLK input is running or not and the link switches to Active Mode when PCLK running is detected. 3) Active Mode BU7963GUW goes to Active Mode when XSD = ‘H’ and PCLK is running. All high-speed signaling channels are enabled. Table 10. Power Modes Power Mode Input Operation XSD PCLK Functions MSDL3 Terminals Shutdown ‘L’ Static (‘L’ or ‘H’) Initialized Disabled (Hi-Z) Standby ‘H’ Static (‘L’ or ‘H’) PCLK detection Disabled (Hi-Z) Active ‘H’ Clock input is active PCLK detection Normal operation (P2S conv) Enabled 4) Power Modes Transition Fig.6 shows the transition of power modes.
