DAC5675

SLAS352B – DECEMBER 2001 – REVISED JUNE 2002

14-BIT, 400-MSPS

DIGITAL-TO-ANALOG CONVERTER

wireless communication systems, high-frequency

FEATURES

direct-digital synthesis (DDS), and waveform

reconstruction in test and measurement applications.

The DAC5675 has excellent spurious free dynamic

range (SFDR) at high intermediate frequencies, which

makes the DAC5675 well suited for multicarrier

transmission in TDMA and CDMA based cellular base

transceiver stations BTS.

– 73 dBc at 30.72-MHz IF, 122.88 MSPS

– 71 dBc at 61.44-MHz IF, 245.76 MSPS

The DAC5675 operates from a single-supply voltage of

3.3 V. Power dissipation is 820 mW at f = 400 MSPS,

clk

= 70 MHz. The DAC5675 provides a nominal

out

full-scale differential current output of 20 mA,

supporting both single-ended and differential

applications. The output current can be directly fed to

the load with no additional external output buffer

required. The output is referred to the analog supply

voltage AVDD.

Differential Scalable Current Outputs: 2 mA to

20 mA

The DAC5675 is manufactured on Texas Instruments

advanced high-speed mixed-signal BiCMOS process.

The DAC5675 comprises a LVDS (low-voltage

differential signaling) interface. LVDS features a low

differential voltage swing with a low constant power

consumption across frequency, allowing for high speed

data transmission with low noise levels, i.e., low

electromagnetic interference (EMI). LVDS is typically

implemented in low-voltage digital CMOS processes,

between the DAC5675 and high-speed low-voltage

CMOS ASICs or FPGAs. The DAC5675 current-

400 MSPS. On-chip edge-triggered input latches

provide for minimum setup and hold times thereby

relaxing interface timing.
