Description

1

CVDD18

1.8 V PLL Supply. CVDD18 supplies the power to the clock receivers, clock multiplier, and clock distribution.

2

REFP/SYNCP

PLL Reference Clock/Synchronization Clock Input, Positive.

3

REFN/SYNCN

PLL Reference Clock/Synchronization Clock Input, Negative.

4

CVDD18

1.8 V PLL Supply. CVDD18 supplies the power to the clock receivers, clock multiplier, and clock distribution.

5

RESET

Reset, Active Low. CMOS levels with respect to DVDD18. Recommended reset pulse length is 1 µs.

6

TXEN

7

DVDD18

Active High Transmit Path Enable. CMOS levels with respect to DVDD18. A low level on this pin triggers two

selectable actions in the DAC. See Register 0x43 in Table 64 for details.

1.8 V Digital Supply. Pin 7 supplies power to the digital core, digital data ports, serial port input/output

pins, RESET, IRQ1, and IRQ2.

8

FRAMEP/PARITYP Frame/Parity Input, Positive.

9

FRAMEN/PARITYN Frame/Parity Input, Negative.

10

D15P

Data Bit 15 (MSB), Positive.

11

D15N

Data Bit 15 (MSB), Negative.

12

DVDD18

1.8 V Digital Supply. Pin 12 supplies the power to the digital core and digital data ports, serial port

input/output pins, RESET, IRQ1, and IRQ2.
