ICS348RIPT集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

描述 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.

特性 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
