Texas Instruments Incorporated (TI) (NASDAQ: TXN) introduced a new 16-bit digital-to-analog converter (DAC). The quad DAC34SH84 is 50-percent faster and uses 50-percent less power than the closest 16-bit DAC alternative, clocking in at 1.5 GSPS and consuming just 362 mW per channel. The DAC34SH84 provides an easy, pin-compatible upgrade from the 1.25-GSPS DAC34H84 for customers wanting to maximize speed in 3G, LTE, GSM and WiMAX wireless base stations and repeaters; microwave point-to-point radio; software defined radio; and waveform generation systems.
Key features and benefits of the DAC34SH84
- Increased bandwidth: 750-MSPS-per-DAC input rate supports up to 600-MHz complex bandwidth for fifth order linearization of 120 MHz – three times wider than the competition when running at maximum sample rates.
- Frequency agility: 2x to 16x interpolation and two independent, 32-bit numerically controlled oscillators lower the interface rate and cost of FPGAs while providing flexibility in frequency planning.
- RF sideband image suppression: On-chip calibration of complete RF transmit path suppresses sideband and local oscillator feed-through while driving IQ modulators, such as the new TRF3705.
Evaluation kits available.
