Pin Function
Transmit/Receive control switch. Pull low to enable receiver function.
This pin is the ground return for the RF section of the IC. The bypass
capacitor connected from the VDDRF to VSSRF should have the shortest
possible lead length. For best performance, connect VSSRF to VSSBB at
the power supply only (i.e. keep VSSBB currents from flowing through
VSSRF return paths).
This is the receive RF input, internally ac-coupled. Connect this pin to the
receive antenna. For applications located in high ambient noise environ-
ments, a fixed value band-pass network may be connected between the
ANT pin and VSSRF to provide additional receive selectivity and input
overload protection.
This pin is the positive supply input for the RF section of the IC. VDDBB and
VDDRF should be connected together directly at the IC pins.
This pin is the positive supply input for the baseband section of the IC.
VDDBB and VDDRF should be connected together at the IC pins.
This capacitor extracts the (DC) average value from the demodulated
waveform which becomes the reference for the internal data slicing com-
parator. Treat as a low-pass RC filter with source impedance of nominally
30k . A standard 20% X7R ceramic capacitor is generally sufficient.
This is the ground return for the baseband section of the IC. The bypass and
output capacitors connected to VSSBB should have the shortest possible
leads lengths. For best performance, connect VSSRF to VSSBB at the
power supply only (i.e., keep VSSBB currents from flowing through VSSRF
return path).
CMOS-level compatible data output signal.
Shutdown-mode logic-level control input. Pull low to enable the receiver.
This pin is internally pulled-up to VDDRF.
No connection
Intergrating capacitor for on-chip AGC (Automatic Gain Control). The Decay/
Attack time-constant (TC) ratio is nominally set as 10:1. Use of 0.47 F or
greater is strongly recommended for best range performance. Use low-
leakage type capacitors for duty-cycle operation (Dip Tantalum, Ceramic,
Polyester).
No connection
This is the timing reference for on-chip tuning and alignment. Connect
crystal between this pin and VSSBB, or drive the input with an AC coupled
