EVALUATION KIT AVAILABLE MAX3522B DOCSIS 3.1 Programmable-Gain Amplifier General Description Benefits and Features The MAX3522B is a programmable gain amplifier (PGA) Delivers +68dBmV Output Power While Meeting designed to exceed the DOCSIS 3.1 Upstream Transmit DOCSIS 3.1 Requirements requirements. By providing dual outputs, the MAX3522B Covers 5MHz204MHz Output Bandwidth eliminates the need for an external RF switch when Dual Outputs Eliminates Need for an External RF selecting between two different upstream bandwidths. Switch The PGA meets the DOCSIS 3.1 spurious limits while transmitting a combined output power of 68dBmV over Programmable Power Codes Allow Operation at Reduced Power Dissipation the RF bandwidth of 5MHz to 204MHz from either output. The gain is controlled in 1dB steps over a 54dB range Exceeds Spurious Requirements with Fully Loaded using a SPI 3-wire interface. The use of Maxim s high- OFDM Allocation at +65dBmV at Modem Output voltage CMOS process enables the device to deliver high Two GPIO s Available for SPI-bus Control of External dynamic range, while minimizing power dissipation under RF Switches a +5V supply rail. 56L 8mm x 8mm x 0.75mm TQFN Package with The MAX3522B is available in a 56-pin 8mm x 8mm x Exposed Paddle 0.75mm TQFN package, and operates over temperature range of 0C to +70C.
