PL60203X
HCSL-Compatible Clock Generator for
PCI Express
General Description
The PL60203X is the smallest, high performance, lowest
power, 2 differential output clock IC available for HCSL
timing applications. PL60203X offers -130dBc at 10kHz
offset at 100MHz, with a very low jitter (2ps TIE RMS),
making it ideal for HCSL applications requiring small size
and low power.
Datasheets and support documentation are available on
Micrel’s web site at:
www.micrel.com.

Notes:
2. Exceeding the absolute maximum ratings may damage the device.
3. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5k in series with 100pF.
4. The device is not guaranteed to function outside its operating ratings.
5. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the device’s most negative potential on the PCB.
