6 / 23 page CX74001 Rx ASIC for CDMA, AMPS, and PCS Applications 6 Skyworks 101134A Proprietary Information and Specifications are Subject to Change March 5, 2002 Table 1. CX74001 Pin Assignments and Signal Descriptions (3 of 4) Pin # Name Description Equivalent Circuit 31 CDMA_MIX_OUT– CDMA differential cellular mixer open collector output. VCC pull up inductor is required, and the output impedance is set by an external matching network. 32 CDMA_MIX_OUT+ CDMA differential cellular mixer open collector output. VCC pull up inductor is required, and the output impedance is set by an external matching network. 33 AMPS_MIX_OUT– AMPS differential mixer open collector output. VCC pull up inductor is required, and the output impedance is set by an external matching network. 34 AMPS_MIX_OUT+ AMPS differential mixer open collector output. VCC pull up inductor is required, and the output impedance is set by an external matching network. 35 PCS_MIXER_OUT– PCS differential mixer open collector output. VCC pull up inductor is required, and the output impedance is set by an external matching network. 36 PCS_MIXER_OUT+ PCS differential mixer open collector output. VCC pull up inductor is required, and the output impedance is set by an external matching network. – + 37 VCC_MIX Voltage supply for the mixers. RF bypass capacitor should be close to pin with minimal trace length. 38 PCS_LO The local oscillator input for the PCS band mixer. 39 CELL_LO The local oscillator input for the cellular band mixer. 40 PCSMIX_BYPASS Low frequency bypass for the PCS mixer. Typically, a 47 nF is connected from pin to ground. 41 PCS_MIX_IN PCS mixer input. Requires AC coupling capacitor 42 CELL_MIX_IN Cellular mixer input 43 RF_BIAS_RES This sets the RF bias current. Typically, a 15 k Ω resistor is connected from the pin to ground. 44 CELL_LNA_BIAS_RES This sets the cellular LNA bias current. Typically, 27 k Ω is connected to ground. |
