ICS8Mx0
Crystal Oscillator: LVCMOS/LVTTL CLOCK OUTPUT
ICS8Mx0
LOW JITTER, HIGH FREQUENCY XTAL OSCILLATOR
• Stable, ultra low jitter, LVCMOS/LVTTL clock generation
• For Gigabit Ethernet, Fibre Channel, PCI-Express, other applications
• Clock output frequencies from 75 to 250 MHz
• One single-ended LVCMOS/LVTTL clock output
• Output Enable (OE) pin (tri-state when low)
• Small 4-pin 5 x 7 x 1.5mm SMT ceramic package
• Low profile package allows back-side PCB mounting
• Pb-free RoHS compliant (by default; no additional code required)
• 2.5V or 3.3V device power supply options
• Commercial (0 to +70 OC) and Industrial (-40 to +85 OC) temperatures
• Frequency stability of ±50 or ±100 ppm
(including initial accuracy, operating temperature variation,
• supply voltage variation, load variation, reflow drift, and aging for 10 years)
Low phase jitter < 1 ps rms maximum (12kHz to 20MHz)
