M2004-01

Frequency Synthesizer

DESCRIPTION

The M2004-01 integrates a high performance Phase

Locked Loop (PLL) with a Voltage Controlled SAW

Oscillator (VCSO) to provide a low jitter Frequency

Translator in a 9mm x 9mm surface mount package.

The internal high “Q” SAW filter provides low jitter

signal performance and determines the maximum

output frequency of the VCSO. A programmable

output divider can divide the VCSO frequency to

achieve an output as low as 38.88MHz.

The input to the Frequency Translator is provided by

selecting between one of two output reference

clocks. The output frequency is an integer multiple

of the input reference frequency.

Parallel and serial control of the output and

feedback dividers is provided via the configuration

logic. An external loop filter sets the PLL bandwidth

which can be optimized to provide jitter attenuation

of the input reference clock.

The M2004-01 is available at SONET/SDH and

10GbE frequencies up to 700MHz.
