● Lowest power consumption upstream amplifier available Maximum output level of 64 dBmV Low power-up/down transients of 4 mVp-p typical at 59 dBmV output Best in class second harmonic distortion Ultra low third harmonic distortion Single +5V supply 63-dB Gain range Gain programmable in 1-dB steps Low transmit output noise floor: 131 nV / √Hz Low transmit-disable output noise: 810 pV / √Hz Two power-down modes DOCSIS and EuroDOCSIS compatible Preliminary and Proprietary 3 OVERVIEW The Microtune 1530 (MT1530) is a low-cost programmable-gain power amplifier IC for use in CATV upstream applications. Specifically, Second harmonic distortion is typically less than -70 dBc, and third harmonic distortion is typically less than -55 dBc at a 59 dBmV output level. A 3-wire digital serial bus controls the variable gain, with gain control available in 1-dB steps and a nominal 63-dB gain range.
