MT1560 UPSTREAM

AMPLIFIER

PRODUCT BRIEF

The MT1560 is a 3.3V programmable

gain upstream amplifier.

cost programmable-gain power

amplifier IC for use in CATV

upstream applications. The MT1560

is a 3.3 volt part optimized for the

DOCSIS 2.0 upstream standard.

range is from 5MHz to 65MHz, and

can output 67dBmV through a 1:1

impedance-ratio transformer. A 3-

wire digital serial bus controls the

variable gain, with gain control

available in 1dB steps and a

nominal 59dB gain range.

an external control pin. The transmit-

disable mode not only minimizes

output noise by shutting off the

output stage, but also maintains its

output impedance at nominal levels.

Output transients are nominally less

than 16mVp-p at 61dBmV output

level during transmit enable/disable

switching.

supply, the amplifier’s typical

current draw at maximum gain, or

minimum attenuation, is 212mA.

Additional internal circuitry reduces

the amplifier’s power consumption

depending on gain setting.

Transmit-disable mode power

supply current is reduced to a

nominal of 18mA. A shutdown mode

further reduces current to a nominal

of 80µA.
