Pin Description (continued)

PIN

NAME

FUNCTION

13

DCOC

DC Offset Capacitor Connection. This is for the RSSI amplifier. Connect a 1μF capacitor from this pin

to ground (see the Typical Application Circuit).

14

OPP

Noninverting Op-Amp Input. This is for the Sallen-Key data filter. Connect a capacitor from this pin to

GND. The value of the capacitor is determined by the data-filter bandwidth.

15

DFFB

Data-Filter Feedback Input. Input for the feedback of the Sallen-Key data filter. Connect a capacitor

from this pin to DSP. The value of the capacitor is determined by the data-filter bandwidth.

16

DSP

Positive Data-Slicer Input. Connect a capacitor from this pin to DFFB. The value of the capacitor is

determined by the data-filter bandwidth.

17

DSN

Negative Data-Slicer Input

18

PDOUT Peak-Detector Output

Power-Supply Voltage Input. For 5.0V operation, VDD is the input to an on-chip voltage regulator

19

VDD

whose 3.2V output drives AVDD. Bypass to ground with a 0.1μF capacitor as close as possible to the

device (see the Typical Application Circuit).

20

DATAOUT Digital Baseband Data Output

—

EP

Exposed Pad. Internally connected to ground. Connect to a large ground plane using multiple vias to

maximize thermal and electrical performance.
