Description
The ICS348 field programmable clock synthesizer generates up to 9 high-quality, high-frequency clock outputs including multiple reference clocks from a low frequency crystal or clock input. The ICS348 has 4 independent on-chip PLLs and is designed to replace crystals and crystal oscillators in most electronic systems.
FEATUREs
• Packaged as 20-pin SSOP (QSOP)
• Eight addressable registers
• Replaces multiple crystals and oscillators
• Output frequencies up to 200 MHz at 3.3V
• Input crystal frequency of 5 to 27 MHz
• Input clock frequency of 2 to 50 MHz
• Up to nine reference outputs
• Up to two sets of four low-skew outputs
• Operating voltages of 3.3 V
• Advanced, low power CMOS process
• For one output clock, use the ICS341 (8-pin). For two
output clocks, use the ICS342 (8-pin). For three
output clocks, use the ICS343 (8-pin). For more than
three outputs, use the ICS345 or ICS348.
• Available in Pb (lead) free packaging
