Hello, I plan to use the DS100BR111 for a SATA re-driver application and have a few questions around the EEPROM configuration mode.
Section 9.1.2 of the data sheet notes that for SAS/SATA applications fast idle must be enabled to pass OOB signaling, this is done by setting Reg 0x28 to 0x4C. However, if loading configuration data from an external EEPROM the EEPROM to SMBUS mapping table 6 stops at Reg 0x27, indicating it is not possible to set fast idle bit with an external EEPROM.
Q1: How do you configure the DS1000BR111 for a SATA application when an external EEPROM is used?
Q2: Reg 0x04 lists bits 7:6 as eSATA Mode Enable what does this do if enabled? Is it the same as eSATA Mode via pin strapping (Fast OOB, Auto Low Power on 100 μs of inactivity. SD stays active)
Q3: Why does the SMBUS to EEPROM mapping in table 6 stop at Reg 0x27 when CH B VOD control is at 0x2D? Is it possible to set CH B VOD in EEPROM Mode?
