2- and 4-output fanout clock buffers

26 April 2022 Analogue, Mixed Signal, LSI

The PI6C49S1504T and PI6C4911502D from Diodes Incorporated are high-performance clock buffers that support up to 1,5 GHz clock frequencies with very low additive jitter.

The PI6C49S1504T is a four-output buffer with a user-selectable output signal format that supports LVPECL, LVDS and HCSL. Its input type is also selectable between two pairs of differential inputs or a crystal input.

The PI6C4911502D is a two-output LVPECL buffer with two integrated, individual, user-configurable dividers that offer scale-down clock signals to multiple destinations. Its input supports LVPECL, LVDS, CML and HCSL.

Both devices support 2,5/3,3 V power supplies with separate input and output supply voltages for level shifting. The PI6C49S1504T is available in the W-QFN5050-32 package and the PI6C4911502D is available in the W-QFN3030-16 package.
