Pin Configuration Table 3. Pin Function Descriptions Pin No. Mnemonic Description Equivalent Circuit 1 IBBP I Channel Baseband Positive Input Pin. Input should be dc-biased to approximately 1.2 V. Nominal characterized ac swing is 1 V p-p (0.7 V to 1.7 V). This makes the differential input 2 V p-p when IBBN is 180 degrees out of phase from IBBP. Circuit A 2 IBBN I Channel Baseband Negative Input Pin. Input should be dc-biased to approximately 1.2 V. Nominal characterized ac swing is 1 V p-p (0.7 V to 1.7 V). This makes the differential input 2 V p-p when IBBN is 180 degrees out of phase from IBBP. Circuit A 3 COM1 Ground Pin for the LO phase splitter and LO buffers. 4 COM1 Ground Pin for the LO phase splitter and LO buffers. 5 LOIN LO Negative Input Pin. Internal dc bias (approximately VPS1 to 800 mV) is supplied. This pin must be ac coupled. Circuit B 6 LOIP LO Positive Input Pin. Internal dc bias (approximately VPS1 to 800 mV) is supplied. This pin must be ac-coupled. Circuit B 7 VPS1 Power Supply Pin for the bias cell and LO buffers. This pin should be decoupled using local 100 pF and 0.01 μF capacitors. 8 ENBL Enable Pin. A high level enables the device; a low level puts the device in sleep mode. Circuit C 9 COM2 Ground Pin for the input stage of output amplifier. 10 COM3 Ground Pin for the output stage of output amplifier. 11 VOUT 50 Ω DC-Coupled RF Output. User must provide ac coupling on this pin. Circuit D 12 VPS2 Power Supply Pin for baseband input voltage to current converters and mixer core. This pin should be decoupled using local 100 pF and 0.01 μF capacitors. 13 COM4 Ground Pin for baseband input voltage to current converters and mixer core. 14 COM4 Ground Pin for baseband input voltage to current converters and mixer core. 15 QBBN Q Channel Baseband Negative Input. Input should be dc biased to approximately 1.2 V. Nominal characterized ac swing is 1 V p-p. This makes the differential input 2 V p-p when QBBN is 180° out of phase from QBBP. Circuit A 16 QBBP Q Channel Baseband Positive Input. Input should be dc-biased to approximately 1.2 V. Nominal characterized ac swing is 1 V p-p. This makes the differential input 2 V p-p when QBBN is 180° out of phase from QBBP. Circuit A |
