Pin Descriptions

Pin Number

Function

Description

VDDCP

Power Supply for charge pump analog section.

BIAS

External bypass decoupling for precision bias circuits.

3,4

CP1,CP2

Charge Pump Outputs.

3VRVDD

Reference supply, 3.3 V nominal.

XREFP

Reference Input. DC bias is generated internally. Normally AC coupled externally.

DVDD3V

DC Power Supply for Digital (CMOS) Circuitry, 3.3 V nominal.

8,23

VCS1, VCS2

Bias control pins for IF amplifiers. Connect to 5V supply through 590 Ohms resistors. Refer to

application section for proper values of resistors to adjust IF amplifier current.

9,10,21,22

IF1_N, IF1_P,

IF2_P, IF1_N

Differential IF outputs. Connect to 5V supply through choke inductors. See application circuit.

11, 20

VBIASIF1, VBIASIF2

Supply voltage pin for IF amplifier’s bias circuits.

Connect to 5V supply through filtering.

12, 19

VGATE1, VGAET2

Bias pins for mixer cores. Set from 4.7V to 5.0V for operating frequency band.

13, 18

RF1, RF2

RF input pins of the mixer, internally matched to 50 Ohms. RF input pins require off chip DC

blocking capacitors. See application circuit.

14, 17

LO_BIAS2,

LO_BIAS1

Bias control pins for LO Amplifiers. Connect to 5V supply through 270 Ohms resistors. Refer to

application section for proper values of resistors to adjust LO amplifier current.

15,24

RSV

Reserved for internal use.Should be left floating.

LOVDD

3V bias supply for LO Drive stages. Refer to application circuit for appropriate filtering and bias

generation information.

CHIP_EN

Chip Enable. Connect to logic high for normal operation.

LON

Negative LO output used for single-ended, differential, or dual output mode.

LOP

Positive LO output used for differential or dual outputs only. While it can drive a separate load from

LO_N, it cannot be used when LO_N is disabled.

VCC1

VCO Analog supply1, 5.0V nominal.

VCC2

VCO Analog Supply 2, 5.0V nominal.

VTUNE

VCO Varactor. Tuning Port Input.

SEN

PLL Serial Port Enable (CMOS) Logic Input.

SDI

PLL Serial Port Data (CMOS) Logic Input.

SCK

PLL Serial Port Clock (CMOS) Logic Input.

LD/SDO

Lock Detect, or Serial Data, or General Purpose (CMOS) Logic Output (GPO).

EXT_VC0_N

External VCO negative input

EXT_VCO_P

External VCO positive input.

VCCHF

Analog supply, 3.3 V nominal

VCCPS

Analog supply, Prescaler, 3.3 V nominal

VCCPD

Analog supply, Phase Detector, 3.3 V nominal

VDDLS

Analog supply, Charge Pump, 5.0 V nominal
