High Output Power Programmable CATV Line Driver

The AD8326 is a high-output power, digitally controlled, vari able gain Amplifier optimized for coaxial line driving applications such as data and Telephony cable modems that are designed to the MCNS-DOCSIS upstream standard. An 8-bit serial word determines the desired output gain over a 53.5 dB range resul ing in gain changes of 0.75 dB/LSB. The AD8326 is offered i two models, each optimized to support the desired output power and resulting performance. The AD8326 comprises a digitally controlled variable attenuato of 0 dB to 54 dB, that is preceded by a low noise, fixed-gai Buffer and is followed by a low distortion high-power amplifie The AD8326 accepts a differential or single-ended input signa The output is designed to drive a 75 ? load, such as coaxial cable, although the AD8326 is capable of driving other loads. When driving 67 dBm into a 75 ? load, the AD8326ARP provides a worst harmonic of only 59 dBc at 21 MHz an 57 dBc at 42 MHz. hen driving 65 dBmV into a 75 ? load the AD8326ARE provides a worst harmonic of only 62 dBc 21 MHz and 60 dBc at 42 MHz By Analog Devices, Inc.
