SL38160

Programmable 4-PLL CG with VCXO and SSCG

Key Features

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.

•

4 Programmable PLLs with up to 5 Clock Outputs

Programmable VCXO and SSCG options

Wide 2.5V to 3.3V +/-10% power supply range

Low power dissipation and low jitter

Programmable Center or Down Spread Modulation

from 0.25 to 5.0%

•

8 to 48 MHz external crystal range

8 to 166 MHz external clock input range

Programmable 1 to 200 MHz clock output range

Integrated internal voltage regulator

FS1/2 functions

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.

Programmable CL at XIN and XOUT pins

Programmable output rise and fall times

16-pin TSSOP package with commercial and

industrial temperature ranges
