CLKIN Requirements
Table 5 summarizes the required characteristics for the CLKIN signal.
This section describes the DC electrical characteristics for the MSC8252.
2.5.1
DDR SDRAM DC Electrical Characteristics
This section describes the DC electrical specifications for the DDR SDRAM interface of the MSC8252.
Note:
DDR2 SDRAM uses VDDDDR(typ) = 1.8 V and DDR3 SDRAM uses VDDDDR(typ) = 1.5 V.
2.5.1.1
DDR2 (1.8 V) SDRAM DC Electrical Characteristics
Table 6 provides the recommended operating conditions for the DDR SDRAM controller when interfacing to DDR2 SDRAM.
Note:
At recommended operating conditions (see Table 3) with VDDDDR =1.8 V.

Notes:
1.
For clock frequencies, see the Clock chapter in the MSC8252 Reference Manual.
2.
Measured at the rising edge and/or the falling edge at VDDIO/2.
3.
Slew rate as measured from ±20% to 80% of voltage swing at clock input.
4.
Phase noise is calculated as FFT of TIE jitter.

Notes:
1.
VDDDDR is expected to be within 50 mV of the DRAM VDD supply voltage at all times. The DRAM and memory controller can
use the same or different sources.
2.
MVREF is expected to be equal to 0.5 × VDDDDR, and to track VDDDDR DC variations as measured at the receiver.
Peak-to-peak noise on MVREF may not exceed ±2% of the DC value.
3.
VTT is not applied directly to the device. It is the supply to which far end signal termination is made and is expected to be equal
to MVREF with a minimum value of MVREF – 0.4 and a maximum value of MVREF + 0.04 V. VTT should track variations in the
DC-level of MVREF.
4.
The voltage regulator for MVREF must be able to supply up to 300 μA.
5.
Input capacitance load for DQ, DQS, and DQS signals are available in the IBIS models.
6.
