SL15101

Programmable Spread Spectrum Clock Generator (SSCG)

Key Features

Description

The SL15101 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.

Low power dissipation

- 7.9mA-typ at 66MHz and VDD=3.3V

- 7.0mA-typ at 66MHz and VDD=2.5V

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

Programmable 4 outputs from 3 to 200MHz

Low Jitter

- 110ps at 66MHz

Programmable Center or Down Spread Modulation

from 0.25 to 5.0%

Up to 4 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 SL15101

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.

8 to 48 MHz external crystal range

8 to 166 MHz external clock range

Integrated internal voltage regulator

Programmable PD#/OE/SSON#/FS functions

Programmable CL at XIN and XOUT pins

Programmable output rise and fall times

Refer to SL15L101 Programmable SSCG product for 1.8V

power supply operation.

Programmable modulation frequency from 30 to

120 kHz
