DTA-110T
Multi-Standard Modulator
with UHF Upconverter
for PCI Bus
The DTA-111 will be available as replacement shortly
DTA-110T Features
- Base version supports ATSC, DVB-C, DVB-H, DVB-T and QAM-A/B/C
- Option for ISDB-T modulation with hierarchical multiplexing
- Option for DTMB modulation supports ADTB-T and DMB-T/H
- Low cost, low power and flexibility is achieved by performing part of the OFDM modulation process in software
- Integrated UHF Upconverter with on-board 400 .. 862-MHz synthesiser
- RF output can be connected directly to a DVB-T terrestrial receiver
- Programming interface (DTAPI) compatible with other DekTec digital-video output adapters
- With DtLoop: DVB-T modulator replacement
- PCI rev 2.2, 32 bit, 33 or 66 MHz bus
DTA-110T Applications
- Driving DVB-T / ISDB-T / DTMB receivers or
DVB-H handhelds for demos, at shows, in electronics stores - Set-top-box development, repair, production testing, performance testing
- Signal validation: check out whether your receivers can handle a new transport stream
- Output adapter for generating a modulated
RF signal directly from your custom application
PC Requirements
- PC selection is critical because of software processing. The DTA-110T will not operate well in PCs that lack sufficient CPU power, memory- or PCI bandwidth
- Maximum of two DTA-110Ts per PC
- P4@2GHz minimum, or equivalent AMD
- 512 MB RAM minimum
- SDK for Windows-2000/XP/2003 and Linux
- No support for 64-bit OS
