DESCRIPTION

AUX_LO –

3

O

PLL auxiliary local oscillator (LO) output (inverting). AUX_LO – is the inverted output from the auxiliary local

oscillator.

AUX_LO+

4

O

PLL auxiliary LO output (noninverting). AUX_LO + is the noninverted output from the auxiliary local oscillator.

16

LNA ground

LNA_IN

15

I

LNA RF input. LNA_IN is the RF input signal to the LNA.

LNA_OUT

13

O

LNA RF output. LNA_OUT is the RF output from the LNA.

LNA_VCC

14

LNA voltage supply. The power supply voltage required to operate the LNA is connected to LNA_VCC. See

Application Information section.

MIX_GND

17

Mixer ground

MIX_IN

18

I

Mixer RF input. MIX_IN is the RF input to the mixer.

MIX_OUT–

20

O

Mixer IF output (inverting). MIX_OUT– is the inverted intermediate frequency (IF) output from the mixer.

MIX_OUT+

19

O

Mixer IF output (noninverting). MIX_OUT+ is the noninverted intermediate frequency (IF) output from the mixer.

OSC1

7

VCO tank port. A coaxial resonator and other tuning components are connected to OSC1 to form the local oscillator

(see Application Information section).

OSC2

5

External oscillator input. An external oscillator can be connected to OSC2. See Application Information section.

PD1

1

I

Power down 1 LSB. PD1, along with PD2, determines which sections of the TRF1015 are placed in standby or

operate mode.

PD2

2

I

Power down 2 MSB. PD2, along with PD1, determines which sections of the TRF1015 are placed in standby or

operate mode.

VCO_BYP

9

VCO bypass port. An external capacitor can be connected to VCO_BYP when the TRF1015 is configured for local

oscillator operation.

VCO_GND

6

VCO ground

VCO_VCC

8

VCO voltage supply. The power supply voltage required to operate the VCO is connected to VCO_VCC (see

Application Information section).
