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.
