Direct Digital Synthesizers: Theory, Design and Applica
... Traditional designs of high bandwidth frequency synthesizers employ the use of a phaselocked-loop (PLL). A direct digital synthesizer (DDS) provides many significant advantages over the PLL approaches. Fast settling time, sub-Hertz frequency resolution, continuous-phase switching response and low ph ...

... typically 70 nA. Switch leakage adds another 40 nA from the input supply. For proper operation, the LM27341/LM27342 EN pin should never be left floating, and the voltage should never exceed VIN + 0.3V. The simplest way to enable the operation of the LM27341/LM27342 is to connect the EN pin to AVIN w ...
