MAX3523

Low-Power DOCSIS 3.1 Programmable-Gain Amplifier

Low Power Upstream Programmable Gain Amplifier (PGA) for DOCSIS 3.1


点击查看特定型号的库存状况。

说明

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 combined 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 0°C to +70°C.
