General 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.
