Figure 15.
Figure 16.
The data input ports of the DAC5672A accept a standard positive coding with data bits DA13 and DB13 being
the most significant bits (MSB). The converter outputs support a clock rate of up to 275 MSPS. The best
performance is typically achieved with a symmetric duty cycle for write and clock; however, the duty cycle may
vary as long as the timing specifications are met. Similarly, the setup and hold times may be chosen within their
specified limits.
All digital inputs of the DAC5672A are CMOS compatible. Figure 17 and Figure 18 show schematics of the
equivalent CMOS digital inputs of the DAC5672A. The pullup and pulldown circuitry is approximately equivalent
to 100k
. The 14-bit digital data input follows the offset positive binary coding scheme. The DAC5672A is
designed to operate with a digital supply (DVDD) of 3 V to 3.6 V.
