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,
14, 17, 19, 20, 23
COMM
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,
IBBP, IBBN
Differential In-Phase and Quadrature Baseband Inputs. These high impedance inputs should be
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.
