MAX3523 Datasheet Low-power Docsis 3.1 Programmable-gain Amplifier

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Click here for production status of specific part numbers. MAX3523 Low-Power DOCSIS 3.

General Description

The MAX3523 is a programmable gain amplifier (PGA) designed to exceed the DOCSIS 3.1 upstream transmit requirements. The PGA meets the DOCSIS 3.1  spurious limits while transmitting a bined output power of 68dBmV over the RF bandwidth of 5MHz to 204MHz. The gain is controlled in 1dB steps over a 60dB range using an SPI 3-wire interface.

The use of Maxim's high-voltage CMOS process enables the device to deliver high dynamic range while minimizing power dissipation under a +5V supply rail.

The MAX3523 is available in a 20-pin 5mm x 5mm x 0.75mm TQFN package, and operates over temperature range of 0ºC to +70ºC.
