LMK00304: input bias

Part Number: LMK00304

Hi team,

The datasheet (Fig. 35 below) implies the part needs input biasing for LVPECL operation, but the eval board (lower snip) doesn’t have this.  Please confirm if it is self-biasing in LVPECL-mode (it is in CMOS) or if resistors are required.

 

 

Thanks,

Connie
