General Description

The 851021 is a 1-to-21 Differential HCSL Fanout Buffer. The

851021 is designed to translate any differential signal levels to

differential HCSL output levels. An external reference resistor is

used to set the value of the current supplied to an external

load/termination resistor. The load resistor value is chosen to equal

the value of the characteristic line impedance of 50

. The 851021 is

characterized at an operating supply voltage of 3.3V.

The differential HCSL outputs, accurate crossover voltage and duty

cycle make the 851021 ideal for interfacing to PCI Express and

FBDIMM applications.

Features

• Twenty-one differential HCSL outputs

• Translates any differential input signal (LVPECL, LVHSTL, LVDS,

HCSL) to HCSL levels without external bias networks

• Maximum output frequency: 250MHz

• Output skew: 395ps (maximum)

• Part-to-part skew: 335ps (maximum)

• Output drift: 140ps (maximum)

• V

OH: 850mV (maximum)

• Full 3.3V supply voltage

• Available in lead-free (RoHS 6) package

• 0°C to 70°C ambient operating temperature
