| PLL620-28/-29 Low Phase Noise VCXO (for 100-200MHz Fund Xtal) FEATURES * * * * * * * 100MHz to 200MHz Fundamental Mode Crystal. Output range: 100 - 200MHz (no PLL). Low Injection Power for crystal 50uW. Sub 0.5pS RMS phase jitter ( 12kHz to 20MHz ). PECL (PLL620-28) or LVDS output (PLL620-29). Supports 2.5V or 3.3V-Power Supply. Available in 16-Pin TSSOP. PIN CONFIGURATION (Top View) DESCRIPTION The PLL620-28/-29 family of XO ICs is specifically designed to work with high frequency fundamental and third overtone crystals. They achieve very low current into the crystal, resulting in better stability. Their very low jitter makes them ideal for the most demanding timing requirements.
