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).
