Description
The SL15316 a programmable Ultra low Power Spread
Spectrum Clock Generator (SSCG) used for reducing
Electromagnetic Interference (EMI).
The product is designed using SpectraLinear proprietary
programmable phase-locked loop (PLL) and Spread
Spectrum Clock (SSC) technology to synthesize and
modulate the input clock. The modulated clock can
significantly reduce the measured EMI levels, and leading
to the compliance with regulatory agency requirements.
Up to 5 output clock frequencies, Spread %, output rise
and fall times, crystal load, modulation frequency and
PD#/OE/SSON#/FS functions can be programmed to meet
the needs of wide range of applications.
The SL15316 operates from 2.5V to 3.3V power supply
voltage range. Separate VDDO power supply is provided
for three (3) clock outputs which can be any value from
3.3V to 2.5V or 1.8V where VDDO≤VDD.
The product is offered in 16-pin TSSOP package with
commercial and industrial grades.
Benefits
Peak EMI reduction of 6 to 16 dB
Fast time-to-market
Cost Reduction
Reduction of PCB layers
Eleminates the need for higher order crystals (Xtals)
and crystal oscillators (XOs)
