19-2092; Rev 0; 7/01 Upstream CATV Amplifier with On-Chip Anti-Alias Filter General Description The MAX3507 is a variable-gain power amplifier for use in CATV upstream transmitters. The variable-gain feature has 55dB of dynamic range and is controlled by a 3-wire SPI™ bus. The device is capable of generating +64dBmV output (16QAM/QPSK) when driven with a +34dBmV nominal input signal. The on-chip anti-alias lowpass filter with 75MHz cutoff frequency saves system design cost and space. The optional positive slope generator provides system design flexibility. The device operates from a single +5V supply and draws 220mA nominal during transmit at max gain (100% duty cycle). For burst-type...
