SL38000-15AH

4-PLL Clock Generator with SSC

Key Features

Description

The SL38000-15AH a fully integrated 4 PLL low power

Clock Generator with a Spread Spectrum Clock (SSC)

function used for reducing Electromagnetic Interference

(EMI) and general purpose frequency synthesizing. The

product is designed using SpectraLinear proprietary phase-

locked loop (PLL) and SSC technology to synthesize and

modulate the input clock. The modulated clock can

significantly reduce the measured EMI levels, leading to the

compliance with regulatory agency requirements.

•

REFOUT=25.000MHz

CLK1=12.000MHz

CLK2=125.000MHz

SSCLK1=133.333MHz with +/-0.25% spread option

SSCLK2=50.000MHz with +0.5% spread option

VDD=VDDO=3.3V +/-10% power supply

25.000MHz external crystal

Integrated internal voltage regulator

PD# control function

SSCLK1 output provides +/-0.25% center-spread and

SSCLK2 output +0.5% up-spread. If SSON=1 both

spreads are on. Spreads can be turned off (no-spread) if

SSON=0.

OE control function (CLK1 only)

SSON enable/disable function function for

SSCLK1/2

The SL38000-15AH operates from 3.3V power supply.

•

Programmable CL at XIN and XOUT pins

Programmable output rise and fall times

The product is offered in 28-pin TSSOP package with both

commercial and industrial temperature grades available.
