Components

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-

tion

of

a

Delta-Sigma

Fractional-N

Frequency

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.

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.
