The PL671-02 is an advanced Spread Spectrum clock generator (SSCG), and a member of PicoPLL™ Programmable Clock family.The PL671-02 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%). In addition, the CSEL pin can be used to toggle the device between 2 pre-programmed configurations. The option of being able to turn ‘ON/OFF’ the Spread Spectrum modulation allows for completing a design with PL671-02 and having the assurance of turning ‘ON’ the EMI modulation, if EMI becomes an issue. The PL671-02’s frequency modulation greatly reduces the fundamental and harmonic frequencies’ peak magnitude, therefore reducing the system level Electro Magnetic Interference (EMI), by as much as 20dB.
