19-1826; Rev 4; 9/06 EVALUATION KIT AVAILABLE Upstream CATV Amplifiers MAX3514/MAX3516/MAX3517 General Description Features The MAX3514/MAX3516/MAX3517 programmable-gain Accurate Gain Control amplifiers are designed for use in CATV upstreamapplications. The MAX3514/MAX3517 drive up to Gain Programmable in 0.5dB Steps +61dBmV (QPSK) into a 75 load when driven with a 56dB of Gain Control Range +34dBmV nominal input signal. The MAX3516 drivesup to +64dBmV (QPSK). Both input and output ports -55dBc Harmonic Distortion at 65MHz Input are differential, requiring that an external balun be used Low Burst On/Off Transient at the output port. The variable gain feature providesgreater than 56dB of dynamic range, which is con- High Efficiency: trolled by an SPITM 3-wire interface. Gain control is 35mA at +34dBmV Out available in 0.5dB steps. The devices operate over a 8mA Transmit Disable Mode frequency range of 5MHz to 65MHz. The MAX3514 is a pin-for-pin compatible upgrade forthe MAX3510. Like the MAX3510, the MAX3514 is inter-nally matched for use with a 2:1 (voltage ratio) balun. Ordering Information The MAX3517 utilizes an external output resistor forgreater load-matching flexibility, and offers the same PIN- PART TEMP RANGE performance as the MAX3514. The MAX3516 is a high- PACKAGE er power version of the MAX3514 with 3dB more gain MAX3514EEP -40°C to +85°C 20 QSOP and output power capability, and is offered in a smaller MAX3514EEP+ -40°C to +85°C 20 QSOP thermally enhanced TSSOP-EP package. MAX3516EUP -40°C to +85°C 20 TSSOP-EP* These devices operate from a single +5VDC supply and MAX3516EUP+ -40°C to +85°C 20 TSSOP-EP* draw 120mA during transmit (100% duty cycle,+61dBmV out). The MAX3516 can be operated at up to MAX3517EEP -40°C to +85°C 20 QSOP +9VDC supply for improved harmonic distortion perfor- MAX3517EEP+ -40°C to +85°C
