The ICS650-27 is a low cost, low jitter, high performance clock synthesizer for networking applications. Using analog Phase-Locked Loop (PLL) techniques, the device accepts a 12.5 MHz or 25 MHz clock or fundamental mode crystal input to produce multiple output clocks for networking chips, PCI devices, SDRAM, and ASICs. The ICS650-27 outputs all have zero ppm.
• Packaged in 20-pin (150 mil) SSOP (QSOP)
• Pb (lead) free package, RoHS compliant
• 12.5 MHz or 25 MHz fundamental crystal or clock input
• Six output clocks with selectable frequencies
• SDRAM frequencies of 67, 83, 100, and 133 MHz
• Buffered crystal reference output
• Zero ppm synthesis error in all clocks
• Ideal for PMC-Sierra’s ATM switch chips
• Full CMOS output swing with 25 mA output drive
capability at TTL levels
• Advanced, low-power, sub-micron CMOS process
• Operating voltage of 3.3 V
• Industrial temperature only
