Manufacturer:VISHAY Description:The VJ1812Y274JXBATA dual, 8-bit, 300Msps digital-to-analog converter (DAC) provides superior dynamic performance in wideband communication systems. The VJ1812Y274JXBATA integrates two 8-bit DAC cores, 4x/2x/1x programmable digital interpolation filters, phase-lock loop (PLL) clock multiplier, and a 1.24V reference. The VJ1812Y274JXBATA sup- ports single-ended and differential modes of operation. The VJ1812Y274JXBATA dynamic performance is maintained over the entire power-supply operating range of 2.7V to 3.3V. The analog outputs support a compliance voltage of -1.0V to +1.25V. The 4x/2x/1x programmable interpolation filters feature excellent passband distortion and noise performance. Interpolating filters minimize the design complexity of ana- log reconstruction filters while lowering the data bus and the clock speeds of the digital interface. The PLL multiplier generates all internal synchronized high-speed clock sig- nals for interpolating filter operation and DAC core conver- sion. The internal PLL helps minimize system complexity and lower cost. To reduce the I/O pin count, the DAC can also operate in interleave data mode. This allows the VJ1812Y274JXBATA to be updated on a single 8-bit bus. The VJ1812Y274JXBATA features digital control of channel gain matching to within 0.4dB in sixteen 0.05dB steps. Channel matching improves sideband suppression in analog quadrature modulation applications. The on-chip 1.24V bandgap reference includes a control amplifier that allows external full-scale adjustments of both chan- nels through a single resistor. The internal reference can be disabled and an external reference may be applied for high-accuracy applications. The VJ1812Y274JXBATA features full-scale current outputs of 2mA to 20mA and operates from a 2.7V to 3.3V single supply. The DAC supports three modes of power-control operation: normal, low-power standby, and complete power-down. In power-down mode, the operating cur- rent is reduced to 1µA. The VJ1812Y274JXBATA is packaged in a 48-pin TQFP with exposed paddle (EP) for enhanced thermal dissipation and is specified for the extended (-40C to +85C) opera- ting temperature range. |
