Pin Configuration Table 3. Pin Function Descriptions Pin No. Mnemonic I/O Description 1 PS2/ADR5/D5 I/O Multipurpose pin: Profile Select Pin (PS2) in Direct Switch Mode, Parallel Port Address Line (ADR5), and Data Line (D5) to program registers. 2 PS1/ADR4/D4 I/O Multipurpose pin: Profile Select Pin (PS1) in Direct Switch Mode or Linear Sweeping Mode, Parallel Port Address Line (ADR4), and Data Line (D4) to program registers. 3 PS0/ADR3/D3 I/O Multipurpose pin: Profile Select Pin (PS0) in Direct Switch Mode or Linear Sweeping Mode, Parallel Port Address Line (ADR3), and Data Line (D3) to program registers. 4 DVDD I Digital Power Supply (1.8 V). 5 DGND I Digital Ground. 6 ADR2/D2 I/O Parallel Port Address Line 2 and Data Line 2. 7 ADR1/D1 I/O Parallel Port Address Line 1and Data Line 1. 8 ADR0/D0 I/O Parallel Port Address Line 0 and Data Line 0. 9 SYNC_CLK O Clock Out. The profile pins [PS0:PS2] and the IO_UPDATE pin (Pin 27) should be set up to the rising edge of this signal to maintain constant pipe line delay through the device. 10 SER/PAR I Serial Port and Parallel Port Selection. Logic low = serial mode; logic high = parallel mode. 11, 15, 18, 21, 23 AGND I Analog Ground. 12, 16, 17, 22 AVDD I Analog Power Supply (1.8 V). 13 REF_CLK I Reference Clock Input. See the REF_CLK Overview section for more details. 14 REF_CLK I Complementary Reference Clock Input. See the REF_CLK Overview section for more details. 19 IOUT O Open Source DAC Complementary Output Source. Current mode. Connect through 50 Ω to AGND. 20 IOUT O Open Source DAC Output Source. Current mode. Connect through 50 Ω to AGND. 24 RSET I Analog Reference. This pin programs the DAC output full-scale reference current. Attach a 4.64 kΩ resistor to AGND. 25 MASTER_RESET I Master Reset, Digital Input (Active High). This pin clears all memory elements and reprograms registers to default values. |
