5 / 28 page  Data Sheet AD5444/AD5446 Rev. E | Page 5 of 28 TIMING CHARACTERISTICS All input signals are specified with tr = tf = 1 ns (10% to 90% of VDD) and timed from a voltage level of (VIL + VIH)/2. VDD = 2.5 V to 5.5 V, VREF = 10 V, IOUT2 = 0 V, temperature range for Y version: −40°C to +125°C; all specifications TMIN to TMAX, unless otherwise noted. Table 2. Parameter1 VDD = 4.5 V to 5.5 V VDD = 2.5 V to 5.5 V Unit Conditions/Comments fSCLK 50 50 MHz max Maximum clock frequency. t1 20 20 ns min SCLK cycle time. t2 8 8 ns min SCLK high time. t3 8 8 ns min SCLK low time. t4 8 8 ns min SYNC falling edge to SCLK active edge setup time. t5 5 5 ns min Data setup time. t6 4.5 4.5 ns min Data hold time. t7 5 5 ns min SYNC rising edge to SCLK active edge setup time t8 30 30 ns min Minimum SYNC high time. t9 23 30 ns min SCLK active edge to SDO valid. Update Rate 2.7 2.7 MSPS Consists of cycle time, SYNC high time, data setup time and output voltage settling time. 1 Guaranteed by design and characterization; not subject to production test. t7 t1 t3 t2 t4 t5 t6 DB15 DB0 SCLK SYNC SDIN t8 Figure 2.
