Silicon Creations 
Short Desc. : Programmable Fractional PLL TSMC 28nm HPCP
Overview :

The Silicon Creations Programmable Delta-Sigma Fractional PLL is a multi-function, general purpose frequency synthesizer. Ultra-wide input and output ranges along with best-in-class jitter performance allow the PLL to be used for almost any clocking application. With excellent supply noise immunity, the PLL is ideal for use in noisy mixed-signal SoC environments. By combining ultra-low jitter output clocks into a low power, low area, widely programmable design, Silicon Creations can greatly simplify an SoC by enabling a single macro to be used for all clocking application in the system.

Features : - • Input frequency range: 1MHz to 1200MHz
- − 10MHz to 1200MHz (fractional mode)
- • Output frequency range: 60MHz to 3800MHz
- • 24 bit fractional accuracy
- − ∆Σ noise cancellation DAC allows fractional mode
- jitter performance to nearly match integer mode performance
- • 4:1 VCO frequency range allows PLL to be optimized for
- minimum jitter or minimum power
- • Isolated analog supply (1.8V) allows for excellent supply
- rejection in noisy SoC applications
- • Lock Detect Signal indicates when frequency lock has
- been achieved
- • Low area (0.06mm2)
