Si53340-45 Data Sheet Low-Jitter LVDS Fanout Clock Buffers with up to 10 LVDS Out- KEY FEATURES puts from Any-Format Input and Wide Frequency Range from dc up to 1250 MHz Ultra-low additive jitter: 50 fs rms Built-in LDOs for high PSRR performance The Si53340-45 family of LVDS fanout buffers is ideal for clock/data distribution and Up to 10 LVDS Outputs redundant clocking applications. These devices feature typical ultra-low jitter of 50 fs Any-format Inputs (LVPECL, Low-Power and operate over a wide frequency range from dc to 1250 MHz. Built-in LDOs deliver LVPECL, LVDS, CML, HCSL, LVCMOS) high PSRR performance and reduces the need for external components simplifying low Wide frequency range: dc to 1250 MHz jitter clock distribution in noisy environments. Output Enable option They are available in multiple configurations and offer a selectable input clock using Multiple configuration options a 2:1 input mux. Other features include independent output enable and built-in format 2:1 Input Mux translation. These buffers can be paired with the Si534x clocks and Si5xx oscillators to RoHS compliant, Pb-free deliver end-to-end clock tree performance.
