• - Manufacturer : Stanford Research systems

• - Model: SRS-CG635

• Special Features : Advanced capabilities include: Optional OCXO (ovenized crystal) or rubidium timebases for ultra-stable frequency integrity External 10 MHz reference input/output for synchronization Precise phase control (resolution better than 20 ps or ~1 nanodegree) Time modulation via external analog input (�5 ns, bandwidth DC�10 kHz) Optional PRBS generator for LVDS-level eye-pattern testing up to ~1.5 Gb/s

The CG635 is a highly precise, low-jitter clock generator offering: A frequency range from 0.001 Hz up to 2.05 Extremely low jitter: less than 1 ps Fine frequency resolution: 16 digits (down to 1 pHz for frequencies under 10 kHz) Fast transitions: rise/fall times around 80 ps Flexible output formats: CMOS, ECL, PECL, LVDS, RS-485, with adjustable amplitude (�5 V offset)
