Components

General Description

The CS2000-OTP is an extremely versatile system

clocking device that utilizes a programmable phase lock

loop. The CS2000-OTP is based on a hybrid analog-

digital PLL architecture comprised of a unique combina-

tion

of

a

Delta-Sigma

Fractional-N

Frequency

Synthesizer and a Digital PLL. This architecture allows

for both frequency synthesis/clock generation from a

stable reference clock as well as generation of a low-jit-

ter clock relative to an external noisy synchronization

clock with frequencies as low as 50 Hz. The CS2000-

OTP has many configuration options which are set once

prior to runtime. At runtime there are three hardware

configuration pins available for mode and feature

selection.

The CS2000-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 30 for complete details.
