DACBP  
Common Bypass Capacitor Connection for Both DACs. A 0.01 µF chip cap from this pin to AVDD  
improves harmonic distortion and SFDR slightly. No connect is permissible (slight SFDR degradation).  
Common Connection for Both DACs to Set the Full-Scale Output Current. RSET = 39.9/IOUT.  
Normal RSET range is from 8 k(5 mA) to 2 k(20 mA).  
This pin provides the connection for the external zero compensation network of the REFCLK  
Multiplier’s PLL loop filter. The zero compensation network consists of a 1.3 kresistor in series  
with a 0.01 µF capacitor. The other side of the network should be connected to AVDD as close as  
possible to Pin 60. For optimum phase noise performance, the REFCLK Multiplier can be bypassed  
by setting the “Bypass PLL” bit in control register 1E.  
DAC RSET  
PLL FILTER

DIFF CLK  
Differential REFCLK Enable. A high level of this pin enables the differential clock inputs, REFCLK  
and REFCLKB ENABLE (Pins 69 and 68 respectively). The minimum differential signal amplitude  
required is 800 mV p-p. The centerpoint or common-mode range of the differential signal ranges  
from 1.6 V to 1.9 V.

REFCLKB  
REFCLK  
The Complementary (180 Degrees Out-of-Phase) Differential Clock Signal. User should tie this pin  
high or low when single-ended clock mode is selected. Same signal levels as REFCLK.  
Single-Ended Reference Clock Input or One of Two Differential Clock Signals. Normal 3.3 V CMOS  
logic levels or 1 V p-p sine wave centered about 1.6 V.  
Selects Between Serial Programming Mode (Logic LOW) and Parallel Programming Mode  
(Logic High).  
Initializes the serial/parallel programming bus to prepare for user programming; sets programming  
registers to a “do-nothing” state defined by the default values seen in the Table V. Active on logic  
high. Asserting MASTER RESET is essential for proper operation upon power-up.
