Analog Devices AD8322 Manuals

AD8322 is a low-cost, digitally controlled variable gain amplifier that supports DOCSIS standard for reverse path transmission gain. It can be programmed in 6 dB steps over a 42 dB range via SPI interface. At 60 dBmV output, the distortion is low, –58dBc SFDR@21MHz, –56dBc SFDR@42MHz. The output noise level is –46dBmV with a bandwidth of 180MHz. The supply voltage is 5V.

The AD8322 is a low-cost, digitally controlled variable gain amplifier. It supports the DOCSIS standard for reverse path transmission, and the gain can be programmed in 6 dB steps over a 42 dB range. At 60 dBmV output, the distortion is low, -58 dBc SFDR at 21 MHz and -56 dBc SFDR at 42 MHz. The output noise level is -46 dBmV, with a bandwidth of 160 kHz. It supports SPI interfaces. It can be used for gain programmable line drivers, DOCSIS-compliant data modems, interactive set-top boxes, PC plug-in modems, and general-purpose digitally controlled variable gain blocks.

AD8128 is a CAT-5 receiver with adjustable line equalization. It features compensation for CAT-5 cable losses, high frequency peaking adjustment, and broadband gain adjustment.

This datasheet provides detailed information on the features of the AD8322, including support for the DOCSIS standard for reverse path transmission gain, programmable in 6 dB steps over a 42 dB range, low distortion, low noise, maintains 75 ohms output impedance, 180 MHz bandwidth, 5 V supply and support for SPI interfaces.
