ASK/FSK Transceiver with Fractional-N PLL

AC ELECTRICAL CHARACTERISTICS (continued)

(Typical Application Circuit, 50Ω system impedance, VAVDD = VDVDD = VPAVDD = VHVIN = +2.1V to +3.6V, fRF = 300MHz to 450MHz,

TA = -40°C to +125°C, unless otherwise noted. Typical values are at VPAVDD = VAVDD = VDVDD = VHVIN = +2.7V, TA = +25°C, unless

otherwise noted.) (Note 1)

Note 1: Supply current, output power, and efficiency are greatly dependent on board layout and PAOUT match.

Note 2: 100% tested at TA = +125°C. Guaranteed by design and characterization overtemperature.

Note 3: 50% duty cycle at 10kHz ASK data (Manchester coded).

Note 4: Guaranteed by design and characterization. Not production tested.

Note 5: Time for final signal detection; does not include baseband filter settling.

Note 6: Efficiency = POUT/(VDD x IDD).

Note 7: Dependent on PCB trace capacitance.

Note 8: The oscillator register (0x05) is set to the nearest integer result of fXTAL/100kHz (see the Oscillator Frequency Register

(Address 0x05) section).

Note 9: Input impedance is measured at the LNAIN pin. Note that the impedance at 315MHz includes the 12nH inductive degenera-

tion from the LNA source to ground. The impedance at 434MHz includes a 10nH inductive degeneration connected from the

LNA source to ground. The equivalent input circuit is approximately 50Ω in series with ~ 2.2pF. The voltage conversion is

measured with the LNA input matching inductor, the degeneration inductor, and the LNA/mixer tank in place, and does not

include the IF filter insertion loss.

Typical Operating Characteristics

(Typical Application Circuit, VPAVDD = VAVDD = VDVDD = VHVIN = +3.0V, fRF = 433.92MHz, TA = +25°C, IF BW = 280kHz, data rate

= 4kbps Manchester encoded, frequency deviation = ±50kHz, BER = 0.2% average RF power, unless otherwise noted.)
