MAX3523 Low-Power DOCSIS 3.1 Programmable-Gain Amplifier
■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 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 0ºC to +70ºC.
■Benefits and Features
●Delivers +68dBmV Output Power While Meeting DOCSIS 3.1 Requirements
●Covers 5MHz–204MHz Output Bandwidth
●3.5W Power Consumption with 5V Supply Voltage
●Programmable Power Codes Allow Operation at Reduced Power Dissipation
●Exceeds Spurious Requirements with Fully Loaded OFDM Allocation at +65dBmV at Modem Output
●20L 5mm x 5mm x 0.75mm TQFN Package with Exposed Paddle
