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.
Input/Output Features
Packaged in 56-pin TSSOP package
2 - Pairs of differential CPU clocks (differential
current mode)
4 - PCI @ 3.3 V
7 - PCI_X @ 3.3 V
2 - REF @ 3.3 V, Fixed
6 - Pairs of differential SSTL2 DDR @ 2.5 V
1 - REF/50 MHz, selectable
Spread spectrum for EMI control
Supports SMBUS index read/write and blocks
read/write operations
Uses external 25 or 50 MHz crystal or clock
CPU output jitter <125 ps
PCI cycle to cycle output jitter <250 ps
DDR cycle to cycle output jitter <150 ps
