Mnemonic Description

1

DSOP

Output Disable. A logic high on this pin disables the RF output. Connect this pin to ground or leave it

floating to enable the output.

2, 5, 8, 11, 12, COMM

14, 17, 19, 20, 23

Input Common Pins. Connect to the ground plane via a low impedance path.

3, 4

LOIP, LOIN

Local Oscillator Inputs.

Single-ended operation: The LOIP pin is driven from the LO source through an ac-coupling capacitor

while the LOIN pin is ac-coupled to ground through a capacitor.

Differential operation: The LOIP and LOIN pins must be driven differentially through ac-coupling

capacitors in this mode of operation.

6, 7, 13, 15,

NC

No Connect. These pins can be left open or tied to ground.

9, 10, 21, 22

QBBN, QBBP, Differential In-Phase and Quadrature Baseband Inputs. These high impedance inputs should be

IBBP, IBBN

dc-biased to the recommended level depending on the version.

ADL5375-05: 500 mV

ADL5375-15: 1500 mV

These inputs should be driven from a low impedance source. Nominal characterized ac signal swing is

500 mV p-p on each pin. This results in a differential drive of 1 V p-p. These inputs are not self-biased

and have to be externally biased.

16

RFOUT

RF Output. Single-ended, 50 Ω internally biased RF output. RFOUT must be ac-coupled to the load.

18, 24

VPS1, VPS2

Positive Supply Voltage Pins. All pins should be connected to the same supply (VS). To ensure adequate

external bypassing, connect 0.1 μF and 1000 pF capacitors between each pin and ground.

EP

Exposed Paddle. Connect to the ground plan via a low impedance path.
