Description
The MAX3510 is a programmable power amplifier for
use in CATV upstream applications. The device outputs
up to 64dBmV (continuous wave) through a 2:1 (voltage
ratio) transformer. It features variable gain controlled by
a 3-wire digital serial bus. Gain control is available in
1dB steps. The device operates over a frequency
range of 5MHz to 65MHz.
The MAX3510 offers a transmit-disable mode, which
places the device in a high-isolation state for use
between bursts in TDMA systems. In this mode the output
stage is shut off, minimizing output noise. When
entering and leaving transmit-disable mode, transients
are kept to 7mV nominal at full gain. In addition, supply
current is reduced to 25mA.
Two power-down modes are available. Software-shutdown
mode permits power-down of all analog circuitry while
maintaining the programmed gain setting. Shutdown
mode disables all circuitry and reduces current consumption
to less than 10µA.
The MAX3510 is available in a 20-pin QSOP package
for the extended-industrial temperature range (-40°C to
+85°C).
