Pin Description
PIN NO.
PIN NAME
TYPE
PIN DESCRIPTION
44-48, 1-3
C(7:0)
Input
8-bit Processor Input Data Bus. C7 is the MSB. Data is written to the control register selected on
A(3:0) on the rising edge of WR when WE is active.
42
WR
Input
Write Clock For The Processor Interface. Parallel data is clocked into the chip on the rising edge
of WR.
40
WE
Input
Write Enable. Active low. WE must be active when writing data to the chip.
35-38
A(3:0)
Input
Processor Interface Address Bus. These pins select the destination register for data on the C(7:0)
bus. A3 is the MSB.
6
CLK
Clock
NCO and DAC Clock. The phase accumulator and DAC output update on the rising edge of this
clock. CLK can be asynchronous to the WR clock.
8
RESET
Input
Reset. Active Low. Resets control registers to their default states (see register description table)
and zeroes the feedback in the phase accumulator. UPDATE must be low for Reset to occur.
30
DGND
(Input)
Connect to DGND. Future serial clock input.
27
DGND
(Input)
Connect to DGND. Future serial data input.
32
DGND
(Input)
Connect to DGND. Future serial sync input.
9
UPDATE
Input
Active Low. Updates the active control registers only. It has no effect on the ENOFR or PH(1:0)
pins. This pin is provided for updating an entire frequency word at once rather than byte by byte.
