PRODUCT DESCRIPTION  
In multichannel wideband transmitters, multiple AD6622s may  
be combined using the chip’s cascadable output summation stage.  
Each channel provides independent serial data inputs that may  
be directly connected to the serial port of DSP chips. User pro-  
grammable FIR filters can be used to filter linear inputs.  
The AD6622 comprises four identical digital Transmit Signal  
Processors (TSPs) complete with synchronization circuitry and  
cascadable wideband channel summation. An external digital-  
to-analog converter (DAC) is all that is required to complete a  
wide band digital up-converter. On-chip tuners allow the relative  
phase and frequency for each RF carrier to be independently  
controlled.  
All control registers and coefficient values are programmed through  
a generic microprocessor interface. Two microprocessor bus  
modes are supported. All inputs and outputs are LVCMOS  
compatible. All outputs are LVCMOS and 5 V TTL compatible.  
Each TSP has three cascaded signal processing elements: a  
RAM-programmable Coefficient interpolating Filter (RCF), a  
programmable Cascaded Integrator Comb (CIC) interpolating  
filter, and a Numerically Controlled Oscillator/tuner (NCO).  
The outputs of the four TSPs are summed and scaled on-chip.
