ICS342MLF Datasheet PDF - Integrated Circuit Systems

Description
The ICS342 is a low cost, dual-output, field programmable clock synthesizer. The ICS342 can generate two output frequencies from 250 kHz to 200 MHz, using up to two independently configurable PLLs. The outputs may employ Spread Spectrum techniques to reduce system electro-magnetic interference (EMI).

FEATUREs
• 8-pin SOIC package
• Highly accurate frequency generation
    • M/N Multiplier PLL: M = 1...2048, N = 1...1024
• Output clock frequencies up to 200 MHz
• Two ROM locations for frequency and spread selection
• Spread spectrum capability for lower system EMI
    • Center or Down Spread up to 4% total
    • Selectable 32 kHz or 120 kHz modulation
• Input crystal frequency from 5 to 27 MHz
• Input clock frequency from 2 to 50 MHz
