RTM680-229 Datasheet DDR/SDRAM Buffer

Manufacturer: Realtek

Datasheet Details

The RTM 680-229 is a 3.3V/2.5V DDR / SDRAM fan out buffer.

The RTM680-229 can be used in conjunction with the RTM560/660/360 or similar clock synthesizer for the VIA 266/333/400 chipset.

The clock chip provides standard serial bus for programming device function.
