Description
The SL15100 a programmable low power Spread
Spectrum Clock Generator (SSCG) used for reducing
Electromagnetic Interference (EMI). The product is
designed using SpectraLinear proprietary EProClock
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.
The output clock frequency, 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 SL15100
operates from 2.5V to 3.3V power supply voltage range.
The product is offered in 8-pin TSSOP package with
commercial and industrial grades.
Refer to SL15101 for up to four (4) programmable clock
outputs and SL15L100/101 Programmable SSCG products
for 1.8V power supply operation.
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)
