Přehled produktu
The MAX3518ETP+ is a DOCSIS 3.0 upstream amplifier in 20 pin TQFN package. This is an integrated CATV upstream amplifier IC designed to meet the DOCSIS 3.0 requirements, while dissipating only 1.25W. The amplifier covers a 5MHz to 85MHz input frequency range (275MHz, 3dB bandwidth) and is capable of transmitting four QPSK modulated carriers, each at +58dBmV, simultaneously within this range. Both input and output ports are differential, requiring that an external balun be used at the output port. The gain is controlled in 1dB steps over a 63dB range using a SPI 3-wire interface. Four power codes are provided to allow maximum supply current to be reduced as determined by distortion requirements. For each power code, supply current is automatically reduced as gain is reduced while maintaining distortion performance. It is used in DOCSIS 3.0 cable modems, VOIP modems and set-top boxes.
- Supply voltage range is 4.75V to 5.25V
- Operating temperature range from -40°C to 85°C
- Low power of 1.25W at 31dB gain, 64dBmV output & 63dB gain control range in 1dB steps
- Ultra-Low 25mW dissipation in transmit-disable mode
- IC draw 300mA at 33dB gain, dropping to 250mA at 31dB gain
- Harmonic distortion of -60dBc at 64dBmV output
- Low burst on/off transient
