PRODUCT DESCRIPTION
The APS3625 active splitter from ANADIGICS accepts
an RF input in the 50 MHz to 1.0 GHz frequency range
and provides five RF outputs with minimal degradation
in signal quality. The single-package surface mount
device amplifies the input signals using highly linear,
low noise amplification stages, and couples the
amplified signal to five separate output paths to drive
video tuner(s), a DOCSIS tuner(s), or other in-band
inputs. The device provides one by-pass output to
maintain a connection when the power is lost, which
is intended for critical signals such as a digital voice
phone. The overall linearity of each tuner path is
maintained across the entire operating frequency
range, ensuring low distortion effects on each output
signal.
Requiring a single +3.3 Volt supply, the active splitter
design is implemented using the ANADIGICS GaAs
MESFET process. The small surface mount QFN
packaging makes this device ideal for use in home
gateways and multiple-tuner set-top boxes, supporting
multiple video outputs, and/or DOCSIS 3.0 and IP
phones.

Note:
Pin 22 must have 3.3 V maintained, even during power loss. This is normally accomplished by a battery backup. Upon
power loss, the FET load switch (SI 1869DH) cuts off power to the five output amplifiers, and puts the APS3625 in bypass
mode.
