Freescale Semiconductor
Electrical Characteristics
Table 18 shows DDR output driver average impedance of the i.MX53 processor.
Table 18. DDR Output Driver Average Impedance1
1 Output driver impedance is controlled across PVTs (process, voltages, and temperatures) using calibration procedure and
pu_*cal, pd_*cal input pins.

2 Output driver impedance deviation (calibration accuracy) is ±5% (max/min impedance) across PVTs.
LPDDR1/DDR2 mode
NVCC_DRAM = 1.8 V
DDR_SEL = 00
Calibration resistance = 300
Ω3
3 Calibration is done against external reference resistor. Value of the resistor should be varied depending on DDR mode and
DDR_SEL setting.

4 If DDR_SEL = ‘01’ or DDR_SEL = ‘11’ are selected with NVCC_DRAM = 1.2 V for LPDDR2 operation, the external reference
resistor value must be 160
Ω for a correct ZQ calibration. In any case, reference resistors attached to the DDR memory devices
should be kept to 240
Ω per the JEDEC standard.
