Product Summary

The max3509eup is a programmable power amplifier for use in CATV upstream applications. The device outputs up to 66dBmV QPSK through a 1:1 transformer. It features variable gain controlled by a 3-wire digital serial bus. Gain control is available in 1dB steps. The max3509eup operates over a 5MHz to 65MHz frequency range. The max3509eup offers a transmit-disable mode, which places the device in a high-isolation state for use between bursts in TDMA systems. In this mode, all analog functions are shut down, minimizing output noise and power consumption. When entering and leaving transmit-disable mode, transients are kept to 25mV nominal at full gain. In addition, supply current is reduced to 7.8mA. The applications of the max3509eup are (1)Telephony-Over-Cable; (2)CATV Status Monitors; (3)OPENCATV Set-Top Boxes; (4)CATV Infrastructures; (5)Cable Modems.
