DESCRIPTION

· The SiT92216 is a 4 differential output and 1 LVCMOS output ultra low-jitter clock fan-out buffer.

· Designed for low jitter, high frequency clock/data distribution.

· Supports driving 50 Ω series or parallel terminated transmission lines.

· Can select clock input from primary, secondary, or crystal source.

· Operates from a 3.3 V/2.5 V core supply and 3.3 V/2.5 V output supply.

· HCSL and LVCMOS output driver can operate at 1.8 V.

FEATURES

· Additive jitter performance of 50 fs RMS.

· Typical output skew between clock outputs is 30 ps.

· Supports PCI-e Gen1 to Gen5.

· Level translation with core supply voltage of 3.3 V/2.5 V and 3.3 V/2.5 V output supply for differential output drivers.

· 1.8 V output supply support for LVCMOS and HCSL driver.

· Inputs consist of primary, secondary, and crystal inputs.

· Input clock receiver can accept LVPECL, LVDS, LVCMOS, SSTL, HCSL, and OSC waveforms.

· Input frequencies supported from DC to 2100 MHz on primary and secondary inputs.

· Crystal input can be overdriven with frequency up to 250 MHz in crystal bypass mode.

· Available in a 32 pin, 5mm x 5mm QFN package.

APPLICATIONS

· Carrier Ethernet.

· 5G Wireless Basestations, 5G Small Cells.
