General Description
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 75
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).
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).
