9 / 107 page  DAC3484 www.ti.com SLAS749E – MARCH 2011 – REVISED NOVEMBER 2015 Pin Functions - NFBGA PIN I/O DESCRIPTION NAME NO. D10, E11, F11, G11, AVDD I Analog supply voltage. (3.3 V) H11, J11, K11, L10 CMOS output for ALARM condition. The ALARM output functionality is defined through the ALARM N12 O config7 register. Default polarity is active low, but can be changed to active high via config0 alarm_out_pol control bit. Full-scale output current bias. For 30-mA full-scale output current, connect 1.28 k Ω to BIASJ H12 O ground. Change the full-scale output current through coarse_dac(3:0) in config3, bit<15:12> Internal clock buffer supply voltage. (1.2 V) CLKVDD C12 I It is recommended to isolate this supply from DIGVDD and DACVDD. LVDS positive input data bits 0 through 15. Internal 100- Ω termination resistor. Data format relative to DATACLKP/N clock is Double Data Rate (DDR). N4, N3, N2, N1, M2, L2, D15P is most significant data bit (MSB) D[15..0]P K2, J2, F2, E2, D2, C2, I A1, A2, A3, A4 D0P is least significant data bit (LSB) The order of the bus can be reversed via config2 revbus bit. P4, P3, P2, P1, M1, L1, D[15..0]N K1, J1, F1, E1, D1, C1, I LVDS negative input data bits 0 through 15. (See D[15:0]P description above) B1, B2, B3, B4 DACCLKP A12 I Positive external LVPECL clock input for DAC core with a self-bias. Complementary external LVPECL clock input for DAC core. (see the DACCLKP DACCLKN A11 I description) D9, E9, E10, F10, G10, DAC core supply voltage. (1.2 V). It is recommended to isolate this supply from CLKVDD DACVDD I H10, J10, K9, K10, L9 and DIGVDD. LVDS positive input data clock. Internal 100- Ω termination resistor. Input data D[15:0]P/N DATACLKP G2 I is latched on both edges of DATACLKP/N (Double Data Rate). DATACLKN G1 I LVDS negative input data clock. (See DATACLKP description) E5, E6, E7, F5, J5, K5, Digital supply voltage. (1.2 V). It is recommended to isolate this supply from CLKVDD and DIGVDD I K6, K7 DACVDD. Used as external reference input when internal reference is disabled through config27 extref_ena = 1b. Used as internal reference output when config27 extref_ena = 0b EXTIO G12 I/O (default). Requires a 0.1-µF decoupling capacitor to AGND when used as reference output. LVDS frame indicator positive input. Internal 100- Ω termination resistor. The main functions of this input are to reset the FIFO pointer or to be used as a syncing source. These two functions are captured with the rising edge of DATACLKP/N. The signal FRAMEP H2 I captured by the falling edge of DATACLKP/N can be used as a block parity bit. The FRAMEP/N signal should be edge-aligned with D[15:0]P/N. Additionally it is used to indicate the beginning of the frame. FRAMEN H1 I LVDS frame indicator negative input. (See the FRAMEP description) A10, A13, A14, B10, B11, B12, B13, C5, C6, C7, C8, C9, C10, C13, D8, D13, D14, E8, E12, E13, F6, F7, F8, F9, F12, F13, G6, G7, G8, GND G9, G13, G14, H6, H7, I These pins are ground for all supplies. H8, H9, H13, H14, J6, J7, J8, J9, J12, J13, K8, K13, L8, L13, L14, M5, M6, M7, M8, M9, M10, M11, M12, M13, N13, P13, P14 IOUTAP B14 O A-Channel DAC current output. Connect directly to ground if unused. IOUTAN C14 O A-Channel DAC complementary current output. Connect directly to ground if unused. IOUTBP F14 O B-Channel DAC current output. Connect directly to ground if unused. IOUTBN E14 O B-Channel DAC complementary current output. Connect directly to ground if unused. IOUTCP J14 O C-Channel DAC current output. Connect directly to ground if unused. Copyright © 2011–2015, Texas Instruments Incorporated Submit Documentation Feedback 9 Product Folder Links: DAC3484 |
