Texas Instruments LMK00725 LVPECL Clock Fanout Buffer

Texas Instruments LMK00725
LVPECL Clock Fanout Buffer

Texas Instruments LMK00725 is a low skew, high-performance clock fanout buffer which can distribute up to five 3.3V LVPECL outputs from one of two inputs, which can accept differential or single-ended inputs. The clock enable input is synchronized internally to eliminate runt or glitch pulses on the outputs when the clock enable pin is asserted or de-asserted. The low additive jitter and phase noise floor and ensured output and part-to-part skew characteristics make the LMK00725 ideal for applications demanding high performance and repeatability.
