STATUS1/SP1
I/O
Lock Detect and Other Status Signals (STATUS1)/I2C Address (SP1). This pin has an internal 40 kΩ pull-
down resistor.
56
STATUS0/SP0
I/O
Lock Detect and Other Status Signals (STATUS0)/I2C Address (SP0). This pin has an internal 40 kΩ pull-
down resistor.

EP
EP, GND
GND
Exposed Paddle. The exposed paddle is the ground connection on the chip. It must be soldered
to the analog ground of the PCB to ensure proper functionality and heat dissipation, noise, and
mechanical strength benefits.
1 P = power, I = input, O = output, I/O = input/output, P/O = power/output, GND = ground.
