Description
The GS6081 is a high-speed BiCMOS integrated circuit
designed to drive one to four 75Ω coaxial cables.
The GS6081 may drive data rates up to 5.94Gb/s and
provides two selectable slew rates in order to achieve
compliance to SMPTE ST 424, SMPTE ST 292 and
SMPTE ST 259.
The GS6081 accepts industry-standard differential input
levels including LVPECL and CML.
Input trace equalization compensates for up to 10 inches of
FR4 trace loss while in HD, 3G and UHD modes. This feature
is enabled and disabled using the EQ_EN pin.
The DISABLE1 and DISABLE2 pins power-down the first and
second output drivers respectively, leaving the serial data
outputs in a high-impedance state. When applied
simultaneously, the entire device is powered-down.
The GS6081 features adjustable output swing using an
external bias resistor. The single-ended output swing is
adjustable from 500mV_pp to 1040mV_pp.
An output signal presence function, the SP pin, indicates
whether an active signal is present at the output of the
GS6081.
The GS6081 can be powered from either a +3.3V or a +2.5V
supply. Power consumption is typically 135mW using a
+2.5V power supply with one output enabled.
The GS6081 is Pb-free, and the encapsulation compound
does not contain halogenated flame retardant.
This component and all homogeneous subcomponents are
RoHS compliant.
