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
