10-Bit, 833/1100 MSPS 1.0V/1.8V CMOS DAC

The KTDA10800 is a low-power high-performance 10-bit digital-to-analog converter (DAC) fully integrated in TSMC 90nm CMOS process. The DAC operates at various conversion rates up to 1.1GSPS with outstanding dynamic performance over a wide bandwidth. Even with clock jitter and other test setup limitations, 72dB SFDR / 9.2ENOB and 61dB SFDR / 8.2 ENOB is measured at 800MSPS with full-scale 41.3 MHz and 193.2 MHz sine wave inputs, respectively. Better than 68dB SFDR is preserved with full-scale 54.3MHz sine wave at 1.05 GSPS. KTDA10800 exceeds all IEEE802.3an specifications for 10GE copper transceiver.

The DAC core requires dual 1.0V/1.8V power supply and consumes 49mW at 800MSPS, the lowest reported in the industry.

Unlike other high-speed DACs at this performance level which requires 10’s or even 100’s of supply/ground pins and expensive low-inductance packages, KTDA10800 only requires total 5 supply and ground pins and can sustain 2.5nH on each pin.

The DAC is fabricated and verified in TSMC 90nm 1-Poly-9-Metal CMOS processes. The core occupies merely 0.36mm2 die area.
