Si53320-28 Data Sheet Low-Jitter LVPECL Fanout Clock Buffers with up to 10 LVPECL KEY FEATURES Outputs 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 Si5332028 family of LVPECL fanout buffers is ideal for clock/data distribution Up to 10 LVPECL Outputs and redundant clocking applications. These devices feature typical ultra-low jitter char- Any-format Inputs (LVPECL, Low-power acteristics of 50 fs and operate over a wide frequency range from dc to 725/1250 LVPECL, LVDS, CML, HCSL, LVCMOS) MHz. Built-in LDOs deliver high PSRR performance and reduce the need for external Wide frequency range: dc to 1250 MHz components, simplifying low-jitter clock distribution in noisy environments. Output Enable option The Si5332028 family is available in multiple configurations, with some versions offer- Multiple configuration options ing a selectable input clock using a 2:1 input mux. Other features include independent Dual Bank option output enable and built-in format translation. These buffers can be paired with the 2:1 Input Mux operation Si534x clocks and Si5xx oscillators to deliver end-to-end clock tree performance.
