GENERAL DESCRIPTION
The ADCA5191 is a medium power gain block amplifier that pro-
vides excellent linearity across a flexible bias range allowing power
efficient design implementation for various applications.
APPLICATIONS
► 45 MHz to 1800 MHz CATV infrastructure amplifier systems
► 5 MHz to 700 MHz upstream
The device provides 25.8 dB of flat gain up to 1800 MHz, making
this ideal for Data Over Cable Service Interface Specification (DOC-
SIS) 4.0 downstream applications. The device is also well suited for
upstream applications to 700 MHz as the output stage. It is conven-
iently packaged in an industry-standard, 5 mm × 5 mm, 32-lead,
lead frame chip-scale package (LFCSP) with an exposed pad on
the bottom of the package for improved thermal performance.
► Remote physical layer (PHY)
► DOCSIS® 3.1 and DOCSIS 4.0 compliant
