The KTA1001 functions as a universal I/Q modulator and digital upconverter for multi-standard communications systems where cost, size, power consumption and dynamic performance are critical. KTA1001 is a feature-rich device, it integrates an optional 1x, 2x, 4x and 8x interpolation filter, on-chip 32bit NCOs, dual on-chip 16bit, 800MSPS DAC, on-chip low phase noise clock multiplier, and other DSP functions into a single chip.
The on-chip IQ auxiliary DACs enable user to cancel LO leakage caused by the upmixer after KTA1001.
The user interface to configure functions is a universal serial port interface. The data interface supports maximum data rate up to 300MSPS. Two input data options are available: dual-port mode and single-port mode.
