Si53360/61/62/65 Data Sheet Low-Jitter, LVCMOS Fanout Clock Buffers with up to 12 outputs KEY FEATURES and Frequency Range from dc to 200 MHz Low additive jitter: 120 fs rms The Si53360/61/62/65 family of LVCMOS fanout buffers is ideal for clock/data distri- Built-in LDOs for high PSRR performance bution and redundant clocking applications. The family utilizes Skyworks advanced CMOS technology to fanout clocks from dc to 200 MHz with guaranteed low additive Up to 12 LVCMOS Outputs from LVCMOS inputs jitter, low skew, and low propagation delay variability. Built-in LDOs deliver high PSRR performance and eliminates the need for external components simplifying low jitter Frequency range: dc to 200 MHz clock distribution in noisy environments. Multiple configuration options Dual Bank option The CMOS buffers are available in multiple configurations with 8 outputs 2:1 Input MUX option (Si53360/61/65), or dual banks of 6 outputs each (Si53362). These buffers can be RoHS compliant, Pb-free paired with the Si534x clock generators and Si5xx oscillators to deliver end-to-end clock tree performance.
