Hi Guru's,
Which is the preferred termination for DDR-2 address lines? the
configuration is 2 devices sharing address lines.

1) One 50E parallel termination to Vtt at the split.
2) Two 100E resistors each at the devices.

The maximum length for any address line is less than 2 inches and the DDR-2
frequency is 533.
