Part Number:DS90UH948-Q1
Dear,
our function block: TBD
We have some question in TI LVDS DeSes (DS90UH948) application circuit design as below
Q1: DS90UH948 not only be configured by I/O pin , but also by register through I2C , Do we need a I2C flash for initial register program? Or it should be program by host through HSD?
Q2: If register program is recommend, what recommend for the sequence of program time and power on ?
Q3: there are four D_GPIO(share with I2S) and eight GPIO, means total 12 GPIO can be used, but we saw “ The back channel contains the I2C, CRC and 4 bits of standard GPIO information with 5 or 20 Mbps line rate (configured by MODE_SEL1). “ is described in datasheet? Do it means only 4 D_GPIO can support backward transmit?
Because it is first we use this deserializer , so if any mis-understand and have wrong question on above, just correct me, thanks in advance.
Q4. have ever seen similar design which used in automotive can share to us for reference.
Best regards,
Lawrence.
