DESCRIPTION
The PL671-02 is an advanced Spread Spectrum clock generator (SSCG), and a member of PhaseLink’s
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

Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permanent damage to the device
and affect product reliability. These conditions represent a stress rating only, and functional operations of the device at these or any other conditions above
the operational limits noted in this specification is not implied. *Operating temperature is guaranteed by design. Parts are tested to commercial grade only.
