Upstream Amplifier

The MT1550 is a low-cost programmable-gain power Amplifier IC for use in CATV upstream applications. The Microtune MT1550 is a 3.3 volt part optimized for the DOCSIS 1.1 upstream standard. The MT1550 also includes an on-chip input anti-aliasing Filter thereby reducing external system costs. The devices specified frequency range is from 5MHz to 65MHz, and CAN output 67dBmV through a 1:1 impedance-ratio transformer. A 3- wire digital serial bus controls the variable gain, with gain control available in 1dB steps and a nominal 59dB gain range. The MT1550 may be disabled via an external control pin. The transmit- disable mode not only minimizes output noise by shutting off the output stage, but also maintains its output impedance at nominal levels. Output transients are nominally less than 16mVp-p at 61dBmV output level during transmit enable/disable switching. By Unkown
