General Description
The Qorvo TGA4898-SL is a quad channel, differential
input, differential output, optical quad limiting driver
amplifier designed for 100 Gb/s optical markets.
The TGA4898-SL consists of four channels of high
performance wideband amplifiers, input DC blocks and
integrated broadband RF Chokes requiring a minimum
of off-chip components. The TGA4898-SL has more
than 25 dB of channel-to-channel isolation and 4 Vppd
output amplitude.
The TGA4898-SL operates with one to three positive
power supplies; no negative supply is required. For 4
Vppd output amplitude, the power consumption is less
than 0.8 W per channel. The TGA4898-SL also has an
internal output power detector for output control.
The TGA4898-SL is RoHS compliant. Evaluation boards
and bias boards are available upon request.
