DESCRIPTION
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%).
In addition, the CSEL[0:1] pins can be used to toggle
the device thru 4 pre-programmed configurations.
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.
greatly reduces the fundamental and harmonic
frequencies’ peak magnitude, therefore reducing the
system level Electro Magnetic Interference (EMI), by
as much as 20dB
