DESCRIPTION

· The SiT92113 is a 5-output low-jitter clock fan-out buffer for high-frequency clock/data distribution. · It supports low-impedance LVCMOS outputs for 50 Ω transmission lines. · It can select a clock input from primary, secondary, or crystal sources, distributing it to 5 LVCMOS outputs. · Operates with independent 3.3 V/2.5 V core and output supplies, no sequencing required.

FEATURES

· Additive jitter performance of 50 fs RMS. · Typical output skew of 30 ps between clock outputs. · Supports level translation with core supply of 3.3 V/2.5 V and output supply of 3.3 V/2.5 V/1.8 V/1.5 V. · Inputs include primary, secondary, and crystal sources, selectable via programming. · Accepts LVPECL, LVDS, LVCMOS, SSTL, HCSL, and OSC waveforms. · Supports crystal frequencies from 8 MHz to 50 MHz, up to 250 MHz in bypass mode. · Available in a 24-pin, 4 mm x 4 mm QFN package.

APPLICATIONS

· Carrier Ethernet. · 5G Wireless Infrastructure and Small Cells.
