PRODUCT DESCRIPTION
The ANADIGICS ACA2601 amplifier for Fiber-to-the-
Home (FTTH) applications is intended to be used
in conjunction with the triplexer in fiber-coax line
terminals. The device is driven by, and amplifies the
output of, the video downstream path photodiode.
The high-impedance input of the ACA2601
eliminates the need for a costly transformer usually
needed to interface to the photodiode, and a low
equivalent input noise level offers excellent
sensitivity. The device provides sufficient linearity to

maintain low CTB and CSO levels in full-bandwidth
(132 channel) systems, even across a wide gain
adjustment range.
The ACA2601 is manufactured using ANADIGICS’s
proven MESFET technology that offers state-of-the-
art reliability, temperature stability and ruggedness.
The device operates from a single +5V supply and
is offered in a 5 mm x 5 mm x 1 mm surface mount
package.
