MX852EB0027
Ultra-Low Jitter XTAL Oscillator with Fanout
ClockWorks® FUSION
General Description
MX852EB0027 CMIC™ (clock management IC) is a
member of the ClockWorks® FUSION family of
devices that integrates the crystal, synthesizer and fanout
buffers in a single 5mm x 7mm LGA Package.
Integrating the entire clock chain delivers 200fs typical
phase noise performance including fanout and crosstalk.
The device operates from a 2.5V or 3.3V power supply.
Applications
• PCI-Express
• Storage
Features
• Generates 5 output clocks
• Frequency and output logic:
-100MHz HCSL x 5
• Integrated quartz crystal for frequency reference
• Typical phase noise:
-100fs (Integration range: 1.875MHz-20MHz)
-200fs (Integration range: 12kHz-20MHz)
• Complete ultra-low jitter clocking solution
• OE on banks 1 and 2
• 2.5V or 3.3V operating voltage range
• ±50ppm total stability
• -40°C to +85°C temperature range
• 38-Pin 5mm x 7mm LGA package
