Pin Configuration Table 3. Pin Function Descriptions Pin No. 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, 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. |
