MAX3523

Low-Power DOCSIS 3.1

Programmable-Gain Ampliﬁer

General Description

Beneﬁts and Features

● Delivers +68dBmV Output Power While Meeting

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.

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

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.

Exposed Paddle

Applications

● DOCSIS 3.1 Upstream (D3.1 US)

● Cable Modem (CM)

Ordering Information appears at end of data sheet.

● Customer Premises Equipment (CPE)
