This amplifier provides excellent linearity and high output power with greater than 30 dB MER for 64 QAM modulation with 39 channels and 52 dBmV per channel. Gain in the minimum attenuation state is typically 39 dB. The internal DSA offers 31.5 dB attenuation range with 0.5 dB steps. This device is optimized for high output power and low current from 8 V bias but can also be operated from 5 V bias with flexibility to adjust DC current with external components. The module provides a power down function for each of the amplifier stages. This amplifier is ideally suited for use in CATV reverse path applications. 1,2 Ordering Information Part Number Package MAAM-011186-TR1000 1000 piece reel MAAM-011186-TR3000 3000 piece reel MAAM-011186-001SMB Sample Test Board, 8 V MAAM-011186-002SMB Sample Test Board, 5 V 1.

V2 Functionality Modes of Operation: Serial, Direct Parallel, and Latched Parallel Mode Truth Table P/S LE Mode 1 X Serial 0 Constant High Direct Parallel 0 Pulsed Latched Parallel Serial Mode The serial control interface (SERIN, CLK, LE, SEROUT) is compatible with the SPI protocol. SPI mode is activated when P/S is kept high. The 6-bit serial word must be loaded with MSB first. After shifting in the 6 bit word, bringing LE high will set the attenuator to the desired state. While LE is high the CLK is masked to protect the data while implementing the change . SEROUT is the SERIN delayed by 6 clock cycles. When P/S is low, the serial control interface is disabled and the serial input register is loaded asynchronously with parallel digital inputs. Direct Parallel Mode The parallel mode is enabled when P/S is set to low. In the direct parallel mode, the attenuator is controlled by the parallel control inputs directly. The LE must be at logic high to control the attenuator in this mode. Latched Parallel Mode In the latched parallel mode, the parallel control inputs will be buffered by registers, and loaded to the outputs when LE is high. The outputs shall not change states when LE is low. Power-up States The power-up (PUP) states will work in both serial and parallel modes, and initiate the attenuator according to the PUP truth table. During power up, the digital inputs shall be held constant for at least 1 μs after VCC reaches 90% of final value. For serial mode, the PUP states will only work when LE is held low. The PUP state shall be locked out after the first LE pulse. Proper operation of power up states requires fast rise time (<200 ns) for VDD-CMOS. 10 M/A-COM Technology Solutions Inc.
