Components

General Description

The CS2000-CP is an extremely versatile system

clocking device that utilizes a programmable phase

lock loop. The CS2000-CP is based on a hybrid ana-

log-digital PLL architecture comprised of a unique

combination 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-

jitter clock relative to an external noisy synchronization

clock. The design is also unique in that it can generate

low-jitter clocks relative to noisy external synchroniza-

tion clocks at frequencies as low as 50 Hz. The

CS2000-CP supports both I²C and SPI for full software

control.

The CS2000-CP is available in a 10-pin MSOP pack-

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

development kits are also available for device evalua-

tion. Please see “Ordering Information” on page 36 for

complete details.
