NETWORKING AND PCI CLOCK SOURCE DATASHEET ICS650-36 The ICS650-36 is a low cost frequency generator designed to support networking and PCI applications. Using analog/digital Phase Locked-Loop PLL techniques, the device uses a standard fundamental mode, inexpensive crystal input of 25 MHz to produce four output clocks supporting LAN, PCI, and 100M SDRAM functions.

NETWORKING AND PCI CLOCK SOURCE

DATASHEET

ICS650-36

The ICS650-36 is a low cost frequency generator designed to support networking and PCI applications. Using analog/digital Phase Locked-Loop PLL techniques, the device uses a standard fundamental mode, inexpensive crystal input of 25 MHz to produce four output clocks supporting LAN, PCI, and 100M SDRAM functions.

The device also has a power down feature that tri-states the clock outputs and turns off the PLL when the PDTS pin is taken low.
• Packaged in 16-pin TSSOP
• Available in Pb lead free package
• Replaces multiple crystals and oscillators
• Input crystal or clock frequency of 25 MHz
• Fixed reference output frequency of 25 MHz
• Selectable output frequencies of 50,
100, and 125 MHz
• Duty cycle of 40/60
• Operating voltage of V
• Advanced, low-power CMOS process
• Industrial and commercial temperature ranges

NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01
