MAX7036
300MHz to 450MHz ASK Receiver
with Internal IF Filter
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.
