Components

General Description

The CS2200-OTP is an extremely versatile system

clocking device that utilizes a programmable phase lock

loop. The CS2200-OTP is based on an analog PLL ar-

chitecture comprised of a Delta-Sigma Fractional-N

Frequency Synthesizer. This architecture allows for fre-

quency synthesis and clock generation from a stable

reference clock. The CS2200-OTP has many configura-

tion options which are set once prior to runtime. At

runtime there are three hardware configuration pins

available for mode and feature selection.

The CS2200-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 23 for complete details.
