MK1493-02A
Networking/PCI Clock Generator
Description
The MK1493-02A is a general purpose clock generator that provides an integrated clocking solution for PCI/Networking applications. It provides two pairs of differential CPU clocks, four PCI clocks, seven PCI_X clocks, two reference clocks, additional clock selectable from REF/50 MHz, and six pairs of SSTL2 DDR at 2.5 V. All complementary outputs operate only from a 2.5 V power supply.
