PL602041
ClockWorks™ PCIe Quad Outputs
Ultra-Low Jitter, HCSL
Frequency Synthesizer
General Description
The PL602041 is a member of the ClockWorksfamily of
devices from Micrel and provides an extremely low-noise
timing solution for PCI Express clock signals.
The device operates from a 3.3V or 2.5V power supply
and synthesizes four HCSL output clocks at 25MHz,
100MHz, 125MHz, and 200MHz. The PL602041 accepts a
25MHz crystal.
Datasheets and support documentation are available on
Micrel’s web site at: www.micrel.com.
Features
Input crystal frequency of 25MHz
Generates four HCSL clock outputs at 25MHz, 100MHz,
125MHz, and 200MHz
2.5V or 3.3V operating range
Typical phase jitter @ 100MHz
(1.875MHz to 20MHz): 105fs
Compliant with PCI Express Gen1, Gen2, and Gen3
Industrial temperature range (40C to +85C)
RoHS and PFOS compliant
Available in 24-pin 4mm x 4mm QFN package
Applications
Servers
Storage systems
Switches and routers
Gigabit Ethernet
Set-top boxes/DVRs
