2:2,Differential-to-LVPECL/LVDS Divider

The 879S216I-02 is a Differential-to-LVPECL/ LVDS Clock Divider which can operate up to 2.5GHz. 879S216I-02 has 2 selectable differential clock inputs. The fully differential architecture and low propagation delay make it ideal for use in clock distribution circuits. 879S216I-02 can divide the input clock by ÷2, ÷4, ÷8 and ÷16. Table 4A lists all the available output dividers.
