The DTA-2116 is an all-digital modulator that generates a high-quality RF signal. Unlike traditional analog modulators, it performs all signal processing digitally, providing increased flexibility and precision. See the functional block diagram below.
The DTA-2116 receives I/Q packets generated by a software modulation process over the PCIe bus. The I/Q packets are buffered in a DDR memory-based transmit FIFO before further processing. The DTA-2116 then performs channel filtering, resampling, gating, and digital upconversion to generate a digitally upconverted modulated signal, which is then converted into an analog RF signal by a high-performance RF-DAC. The analog RF signal is low-pass filtered and amplified or attenuated with a programmable gain.
The DTA-2116's master clock generator synchronizes the device's oscillator to either an internal 10MHz oscillator or an external 10MHz timing reference for more accurate or synchronized timing. The Sync block enables synchronous starting with the 1pps input signal, facilitating precise synchronization between multiple modulators.
DTA-2111B – Multi-Standard Cable/Terrestrial Modulator for PCIe
The DTA-2111B is a cost-effective cable/terrestrial modulator designed for OEM applications, whereas the DTA-2116 is a premium modulator for R&D and broadcasting, with satellite support and external synchronization. While more advanced, the DTA-2116 comes at a higher cost.
DTA-2115B – All-Standard VHF/UHF/L-Band Modulator for PCIe
This card has similar specs to the DTA-2116 but with a narrower 0-2GHz frequency range and an 8 channel option not available on the DTA-2116. However, the DTA-2115B has limited synchronization capabilities. and is not recommended for new designs due to containing older components.
DTU-315 – All-Standard 0-2GHz Modulator for USB-3
The DTU-315 is designed for portability, while the DTA-2116 is intended for rack-mounted use and has slightly better specs. Both modulators use all-digital modulation and upconversion.
