FUNCTION
No Connection. Internally not connected.
Digital Positive Supply Voltage. Bypass to GND with 0.1μF and 0.01μF capacitors placed as close to
the pin as possible.
Frequency Select. Internally pulled down to GND when the part is not in standby mode. Set FSEL =
0/TOGGLE = 0 to select continuous 390MHz, and FSEL = 1/TOGGLE = 0 to select continuous
315MHz. See Table 1 for detailed mode description.
Output Capacitance Adjustment 1. Logic pin to control the capacitance on PAOUT (see Table 2). Set
CAP1 = 1 to add 0.5pF shunt capacitance at PAOUT when at 315MHz. Internally pulled down to GND
when the part is not in standby mode.
Output Capacitance Adjustment 2. Logic pin to control the capacitance on PAOUT (see Table 2). Set
CAP2 = 1 to add 1pF shunt capacitance at PAOUT when at 315MHz. Internally pulled down to GND
when the part is not in standby mode.
Output Capacitance Adjustment 3. Logic pin to control the capacitance on PAOUT (see Table 2). Set
CAP3 = 1 to add 2pF shunt capacitance at PAOUT when at 315MHz. Internally pulled down to GND
when the part is not in standby mode.
Output Capacitance Adjustment 4. Logic pin to control the capacitance on PAOUT (see Table 2). Set
CAP4 = 1 to add 4pF shunt capacitance at PAOUT when at 315MHz. Internally pulled down to GND
when the part is not in standby mode.
Power Amplifier Output. Requires a pullup inductor to the supply voltage or ROUT. The pullup
inductor can be part of the output-matching network.
Envelope-Shaping Output. ROUT controls the power amplifier envelope’s rise and fall times. Connect
ROUT to PA pullup inductor or optional power-adjust resistor. Bypass the inductor to GND as close to
the inductor as possible with 680pF and 220pF capacitors.
Power Amplifier Supply Voltage. Bypass to GND with 0.01μF and 220pF capacitors placed as close
to the pin as possible.
Analog Positive Supply Voltage. Bypass AVDD to GND with 0.1μF and 0.01μF capacitors placed as
close to the pin as possible.
Crystal Input 2. XTAL2 can be driven from an AC-coupled external reference.
Crystal Input 1. Bypass to GND if XTAL2 is driven from an AC-coupled external reference.
Toggle Pin. Set TOGGLE = 1 to enable toggle operation (see the Detailed Description section and
Table 1 for operating mode). Internally pulled down to GND when the part is not in standby mode.
Enable Pin. Drive high for normal operation, and drive low or leave unconnected to put the device in
standby mode. Internally pulled down to GND.
ASK Data Input. Internally pulled down to GND. Auto power-up occurs upon activity (see the Detailed
Description section.)
No connection. Must remain unconnected.
Exposed Paddle. Internally connected to ground (the only ground for the MAX7058.) Requires low-
inductance path (e.g., one or more vias) to solid ground plane. Solder evenly to the board’s ground
plane for proper operation.
