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.

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.
