Factory Programmable Quad PLL Clock Generator with VCXO
Features
■ Fully integrated phase-locked loops (PLLs)
■ Small quad flat no-leads (QFN) package option
❐ 40% smaller than 20-pin TSSOP
❐ 22% smaller than 16-pin TSSOP
■ Selectable output frequency
■ Programmable output frequencies
■ Output frequency range:
❐ 1 MHz to 166 MHz
■ Input frequency range:
❐ Crystal: 10 MHz to 30 MHz
❐ External reference: 1 MHz to 100 MHz
■ Analog voltage-control crystal oscillator (VCXO)
■ 16-/20-pin TSSOP and 32-pin QFN packages
■ 3.3-V operation with 2.5-V output buffer option
Benefits
■ Meets most digital set top box, DVD recorder, and DTV
application requirements
■ Multiple high-performance PLLs allow synthesis of unrelated
frequencies
■ Integration eliminates the need for external loop filter
components
■ Meets critical timing requirements in complex system designs
■ Enables application compatibility
■ Complete VCXO solution with ±120 ppm (typical pull range)
