We design our custom board based on MCIMX53-START-R.
DDR_Vref is generated in MC34708, But MC34708 have Silicon Errata.
The contents of Silicon Errata as follows.(MC34708ER Rev. 5.0, 4/2012)
"Description:VREFDDR output should be 2% accurate over temp. At 85°C, the output accuracy of
VREFDDR can go as high as 6.5%."
"Workaround:Use an external resistor divider to generate VREFDDR"
Would Freescale make a MCIMX53-START-R before this was informed of it?
Should I use an external resistor divider? Or May I use a MC34708 ?
