Upstream CATV Amplifiers

General Description

Features

The MAX3514/MAX3516/MAX3517 programmable-gain

amplifiers are designed for use in CATV upstream

applications. The MAX3514/MAX3517 drive up to

+61dBmV (QPSK) into a 75Ω load when driven with a

+34dBmV nominal input signal. The MAX3516 drives

up to +64dBmV (QPSK). Both input and output ports

are differential, requiring that an external balun be used

at the output port. The variable gain feature provides

greater than 56dB of dynamic range, which is con-

trolled by an SPI™ 3-wire interface. Gain control is

available in 0.5dB steps. The devices operate over a

frequency range of 5MHz to 65MHz.

The MAX3514 is a pin-for-pin compatible upgrade for

the MAX3510. Like the MAX3510, the MAX3514 is inter-

nally matched for use with a 2:1 (voltage ratio) balun.

The MAX3517 utilizes an external output resistor for

greater load-matching flexibility, and offers the same

performance as the MAX3514. The MAX3516 is a high-

er power version of the MAX3514 with 3dB more gain

and output power capability, and is offered in a smaller

thermally enhanced TSSOP-EP package.

These devices operate from a single +5VDC supply and

draw 120mA during transmit (100% duty cycle,

+61dBmV out). The MAX3516 can be operated at up to

+9VDC supply for improved harmonic distortion perfor-

mance. The bias current is automatically adjusted based

on the output level to increase efficiency. Additionally,

the devices are shut off between bursts to minimize

noise and save power while still maintaining a match at

the output port. Shutdown mode disables all circuitry and

reduces current consumption to 10µA (typ).

Pin Configuration

The MAX3514/MAX3517 are available in a 20-pin QSOP

package and the MAX3516 is available in a 20-pin

TSSOP-EP package. All devices operate in the extend-

ed industrial temperature range (-40°C to +85°C).
