Frequency Translator provides less than 1 ps rms jitter.

Press Release Summary:



M2004-01 integrates PLL with VCSO SAW technology to provide ultra low jitter reference clocks. Translator is housed in 9 x 9 mm surface mount package, and is available at SONET/SDH and 10 GbE frequencies up to 700 MHz. It features 2 selectable reference clock inputs, serial or parallel programming of feedback and output frequency dividers, external loop filter elements, differential LVPECL outputs, and +3.3 V operation.



Original Press Release:


New M2004-01 Frequency Translator


SAW based Communications Clock Device Provides Less Than 1ps RMS Jitter

Worcester, Mass. Micro Networks, an Integrated Circuit Systems Company (NASDAQ - ICST) announces the New M2004-01 Frequency Translator. The M2004-01 integrates a high performance PLL
with VCSO SAW technology to provide ultra low jitter reference clocks, meeting a critical requirement for high speed SONET/SDH Optical and Transponder applications. The M2004-01 is packaged in a 9mm x 9mm surface mount package, and is smaller than most
existing VCSO solutions, while providing more functionality.

The PLL IC incorporates on-chip VCSO circuitry. The High Q SAW filter used to provide the low jitter performance is mounted off-chip within the 9mm x 9mm package. The output frequency of the device is factory set by installing a custom SAW filter of the
desired frequency. The frequency translator is available at SONET/SDH and 10GbE frequencies up to 700MHz.

The M2004-01 Frequency Translator features: ultra low jitter SAW frequency control, two selectable reference clock inputs, serial or parallel programming of feedback and output frequency dividers, external loop filter elements, differential LVPECL outputs and +3.3V operation.

Serial or parallel programming of the PLL feedback divider (6bits) and output divider (2bits) allow operation with a wide range of input reference frequencies and the ability to divide the VCSO frequency by 1, 2, 4, or 8.

The M2004-01 minimizes design and manufacturing problems associated with low jitter clock synthesis circuits, and helps reduce overall board space and circuit complexity while providing cost savings.
