PLL PL671-01
The PL671-01 is an advanced programmable Spread Spectrum clock generator (PSSCG), and a member of PhaseLink’s PicoPLL™ Programmable Clock family. The PL671-01 offers up to three 200MHz outputs, and allows for programming the modulation type (Center or Down Spread) as well as 16 modulation magnitudes (±0.125% to ±2.0% or -0.25% to -4.0%). The option of being able to turn ‘ON/OFF’ the Spread Spectrum modulation allows for completing a design with PL671-01 and having the assurance of turning ‘ON’ the EMI modulation, if EMI becomes an issue.| Part No. | PL671-01 |

DESCRIPTION
In addition, the CSEL[0:1] pins can be used to toggle the device thru 4 pre-programmed configurations. The PL671-01’s frequency modulation greatly reduces the fundamental and harmonic frequencies’ peak magnitude, therefore reducing the system level Electro Magnetic Interference (EMI), by a...
