PIN | TYPE | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
DAP | DAP | GND | Die Attach Pad. Connect to the PCB ground plane for heat dissipation. |
1, 19, 28 | GND | GND | Ground |
2, 5 | VCCOA | PWR | Power supply for Bank A Output buffers. VCCOA can operate from 3.3 V or 2.5 V. The VCCOA pins are internally tied together. Bypass with a 0.1 uF low-ESR capacitor placed very close to each Vcco pin. (1) |
3, 4 | CLKoutA0, CLKoutA0* | O | Differential clock output A0. Output type set by CLKoutA_TYPE pins. |
6, 7 | CLKoutA1, CLKoutA1* | O | Differential clock output A1. Output type set by CLKoutA_TYPE pins. |
8, 9 | CLKoutA2, CLKoutA2* | O | Differential clock output A2. Output type set by CLKoutA_TYPE pins. |
10, 36 | CLKoutA_TYPE0, CLKoutA_TYPE1 | I | Bank A output buffer type selection pins (2) |
11, 32 | Vcc | PWR | Power supply for Core and Input buffer blocks. The Vcc supply operates from 3.3 V. Bypass with a 0.1 uF low-ESR capacitor placed very close to each Vcc pin. |
12 | OSCin | I | Input for crystal. Can also be driven by a XO, TCXO, or other external single-ended clock. |
13 | OSCout | O | Output for crystal. Leave OSCout floating if OSCin is driven by a single-ended clock. |
14, 17 | CLKin_SEL0, CLKin_SEL1 | I | Clock input selection pins (2) |
15, 16 | CLKin0, CLKin0* | I | Universal clock input 0 (differential/single-ended) |
18, 29 | CLKoutB_TYPE0, CLKoutB_TYPE1 | I | Bank B output buffer type selection pins (2) |
20, 21 | CLKoutB2*, CLKoutB2 | O | Differential clock output B2. Output type set by CLKoutB_TYPE pins. |
22, 23 | CLKoutB1*, CLKoutB1 | O | Differential clock output B1. Output type set by CLKoutB_TYPE pins. |
24, 27 | VCCOB | PWR | Power supply for Bank B Output buffers. VCCOB can operate from 3.3 V or 2.5 V. The VCCOB pins are internally tied together. Bypass with a 0.1 uF low-ESR capacitor placed very close to each Vcco pin. (1) |
25, 26 | CLKoutB0*, CLKoutB0 | O | Differential clock output B0. Output type set by CLKoutB_TYPE pins. |
30, 31 | CLKin1*, CLKin1 | I | Universal clock input 1 (differential/single-ended) |
33 | REFout | O | LVCMOS reference output. Enable output by pulling REFout_EN pin high. |
34 | VCCOC | PWR | Power supply for REFout Output buffer. VCCOC can operate from 3.3 V or 2.5 V. Bypass with a 0.1 uF low-ESR capacitor placed very close to each Vcco pin. (1) |
35 | REFout_EN | I | REFout enable input. Enable signal is internally synchronized to selected clock input. (2) |
