The PL671-00 clock outputs can be programmed up to 200MHz (3.3V) or 166MHz (2.5V), and has 16 modulation magnitudes (±0.125 to ±2.0% or -0.25 to -4.0%) to choose from for use in Center or Down Spread modulation applications. In addition, 2 configuration pins can be programmed to allow cycling the device through 4 preprogrammed states*. The option of being able to turn ‘ON/OFF’ the Spread Spectrum modulation allows for completing a design with PL671-00 and having the assurance of turning ‘ON’ the EMI modulation if EMI becomes an issue*. The PL671-00’s spread spectrum modulation greatly reduces the fundamental and harmonic frequencies’ peak magnitude, reducing the system level electromagnetic radiation by as much as 20dB. *Note: Requires 6-pa...
