| Main-Chip Clock Generator for VIA PT800 Chipsets |
| |
|
General Description |
The RTM360-108 is a 48-pin package, main-chip frequency generator that meets clock synthesizer/driver specifications of VIA P4X400/PT800 chipset solutions for Intel® P4. The RTM360-108 can be implemented with a Realtek DDR clock buffer, the RTM680-256 (48-pin SSOP, supporting 4 DDR) or the RTM680-229 (28-pin SSOP, supporting 2 DDR). The RTM360-108 provides a standard serial bus for programmable clock functions. Through this interface, spread spectrum technology can be enabled to reduce EMI. |
