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 driving 50 Ω series or parallel terminated transmission lines.
· It can select a clock input from primary, secondary, or crystal sources, which can be single-ended or fully differential.
· The selected clock is distributed to 5 LVCMOS output drivers.
· It operates with independent 3.3 V/2.5 V core and output supplies, requiring no supply sequencing.

FEATURES

· Additive jitter performance of 50 fs RMS.
· Typical output skew between clock outputs is 30 ps.
· Supports level translation with core supply voltage 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 input select pins.
· Input clock receiver accepts LVPECL, LVDS, LVCMOS, SSTL, HCSL, and OSC waveforms.
· Supports crystal frequencies from 8 MHz to 50 MHz, with crystal bypass mode supporting up to 250 MHz.
· Available in a 24-pin, 4 mm x 4 mm QFN package.

APPLICATIONS

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