| ACA2601 Fiber-to-the-Home RF Amplifier PRELIMINARY DATA SHEET - Rev 1.4 FEATURES * * * * * 50 - 870 MHz Operating Frequency High Linearity: 65 dBc CTB/CSO (79 Chan.) Low Equivalent Input Noise: 4.5 pA/rtHz 20 dB Gain Adjust 400 Differential Input Impedance: No Transformer Required for Interface to Photodiode Single +5 V Supply 5 mm x 5 mm x 1 mm Surface Mount Package RoHS Compliant Package * * * APPLICATIONS * FTTH RF Amplifier Used in Conjunction With Triplexer in Fiber-Coax Line Terminals S29 Package 28 Pin QFN 5 mm x 5 mm x 1 mm PRODUCT DESCRIPTION The ANADIGICS ACA2601 amplifier for Fiber-to-theHome (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 Supply 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-theart 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.
