LVCMOS/LVTTL CLOCK OSCILLATOR
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 75MHz to 250MHz
• One single-ended LVCMOS/LVTTL clock output
• Output Enable (OE) pin (high impedance – when low)
• Small 4-pin 5mm x 7mm x 1.5mm SMT ceramic package
• Low profile package allows back-side PCB mounting
• Pb-free RoHS compliant (by default; no additional code required)
• 3.3V or 2.5V device power supply options

• Commercial (0 to +70 C) and Industrial (-40 to +85 C) temperatures
• Frequency stability of 50ppm or 100ppm
(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)
4-pin CERHERMETIC 5mm x 7mm x 1.5mm SMT
