Product Summary

The MAX3514EEP-T programmable-gain amplifier is designed for use in CATV upstream applications. The MAX3514EEP-T drives up to +61dBmV (QPSK) into a 75Ω load when driven with a +34dBmV nominal input signal. The MAX3514EEP-T 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 controlled by an SPI. 3-wire interface. Gain control is available in 0.5dB steps. The MAX3514EEP-T operates over a frequency range of 5MHz to 65MHz. The MAX3514EEP-T is a pin-for-pin compatible upgrade for the MAX3510. Like the MAX3510, the MAX3514EEP-T is internally matched for use with a 2:1 (voltage ratio) balun.
