CS2100-OTP

Fractional-N Clock Multiplier

Features

General Description

The CS2100-OTP is an extremely versatile system

clocking device that utilizes a programmable phase lock

loop. The CS2100-OTP is based on a hybrid analog-

digital PLL architecture comprised of a unique combina-

Clock Multiplier / Jitter Reduction

–

Generates a Low Jitter 6 - 75 MHz Clock

from a Jittery or Intermittent 50 Hz to

30 MHz Clock Source

tion of

Delta-Sigma Fractional-N Frequency

Highly Accurate PLL Multiplication Factor

Synthesizer and a Digital PLL. This architecture allows

for generation of a low-jitter clock relative to an external

noisy synchronization clock with frequencies as low as

50 Hz. The CS2100-OTP has many configuration op-

tions which are set once prior to runtime. At runtime

there are three hardware configuration pins available for

mode and feature selection.

–

Maximum Error Less Than 1 PPM in High-

Resolution Mode

One-Time Programmability

–

Configurable Hardware Control Pins

Configurable Auxiliary Output

Flexible Sourcing of Reference Clock

The CS2100-OTP is available in a 10-pin MSOP pack-

age in Commercial (-10°C to +70°C) grade. Customer

development kits are also available for custom device

prototyping, small production programming, and device

evaluation. Please see “Ordering Information” on

page 28 for complete details.
