4 / 55 page  LMX2581E SNAS665 – MAY 2015 www.ti.com Pin Functions (continued) PIN TYPE DESCRIPTION NUMBER NAME 19 VbiasVCO Output Bias circuitry for the VCO. Place a 2.2 µF capacitor to GND (Preferably close to Pin 18). VCO tuning voltage input. See the functional description regarding the minimum 20 Vtune Input capacitance to put at this pin. 21 GND GND VCO ground. VCO capacitance. Place a capacitor to GND (Preferably close to Pin 18). This value should 22 VrefVCO Output be between 5% and 10% of the capacitance at pin 24. Recommended value is 1 µF. VCO bias voltage temperature compensation circuit. Place a minimum 10 µF capacitor to 23 VbiasCOMP Output GND (Preferably close to Pin 18). If it is possible, use more capacitance to slightly improve VCO phase noise. VCO regulator output. Place a minimum 10 µF capacitor to GND (Preferably close to Pin 24 VregVCO Output 18). If it is possible, use more capacitance to slightly improve VCO phase noise. Multiplexed output that can perform lock detect, PLL N and R counter outputs, Readback, 25 LD Output and other diagnostic functions. 26 BUFEN Input Enable pin for the RF output buffer. If not used, this can be overwritten in software. 27 GND GND Digital Ground. 28 VccDIG Supply Digital Supply. 29 OSCin Input Reference input clock. Multiplexed output that can perform lock detect, PLL N and R counter outputs, Readback, 30 MUXout Output and other diagnostic functions.. 31 GND GND Ground for the fractional circuitry. 32 VccFRAC Supply Supply for the fractional circuitry. 4 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Product Folder Links: LMX2581E |
