Pin Descriptions
SD
Shutdown Active Low. This signal is used to shut down and activate
the part. It is 1.8V to 5V compatible. During shutdown, the part
draws less than 100nA input current. Coming out of shutdown takes
3.5ms and going into shutdown is instantaneous.
SYNC
External clock input. This pin allows the chip to be synchronized to a
system clock. This helps in folding the spectral components and the
switching harmonic out of band of interest. The range of SYNC
frequency is from 250kHz to 800kHz.
IN+
Positive Differential Input.
IN-
Negative Differential Input.

O
+
Positive BTL output.
