Description
The SL38160 4 PLL programmable low power Clock
Generator with SSCG and VCXO functions used for
reducing Electromagnetic Interference (EMI) and general
purpose frequency synthesizing. 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 5 output clock frequencies, spread %, output rise and
fall times for each clock outputs, crystal load, spread
modulation frequency and FS1/2 functions can be
programmed to meet the needs of wide range of
applications. The SL38160 operates from 2.5V to 3.3V, +/-
10% power supply voltage range. The product is offered in
16-pin TSSOP package with commercial and industrial
grades.
Benefits
Complete VCXO with +/-120ppm typical pull range
Peak EMI reduction of 8 to 16 dB
Fast time-to-market
Cost Reduction
Reduction of PCB layers
Eleminates the need for XOs and VCXOs
