Description
The SL15303 a programmable low power Spread
Spectrum Clock Generator (SSCG) used for reducing
Electromagnetic Interference (EMI).
The product is designed using SpectraLinear proprietary
programmable EProClock 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 3 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 SL15300 operates from 2.5V to 3.3V+/-10% or 1.8V+/-
5% power supply voltage ranges. Contact SLI for 1.8+/-5%
power supply operation specifications.
The product is offered in 8-pin TSSOP package with
commercial and industrial grades.
Benefits
Peak EMI reduction of 8 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)
