PRODUCT DESCRIPTION

The ANADIGICS ACA2604 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.

CSO levels in full-bandwidth (132 channel) systems,

even across a wide gain adjustment range.

The ACA2604 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 +5 V supply and

is offered in a 5 mm x 5 mm x 1 mm surface mount

package.

The high-impedance input of theACA2604 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
