Equalization Control
BST_2
BST_1
BST_0
23
I, CMOS BST_0, BST_1, and BST_2 select the equalizer boost level for EQ channels. BST_0,
14
BST_1, and BST_2 are internally pulled high.
37
Device Control
EN
44
I, CMOS Enable Equalizer inputs. When held High, normal operation is selected. When held Low,
standby mode is selected. EN is internally pulled high.
FEB
21
I, CMOS Force External Boost. When held high, the equalizer boost setting is controlled by the BST_
[0:2] pins. When held low, the equalizer boost level is controlled through the SMBus (see
Table 1) control pins. FEB is internally pulled high.
SD
45
O, CMOS Equalizer Clock Channel Signal Detect Output. Produces a high when signal is detect.
POWER
VDD
3, 6, 7,
I, Power VDD = 3.3V ± 10%. VDDpins should be tied to the VDD plane through a low inductance path.
10, 13,
A 0.01µF bypass capacitor should be connected between each VDD pin to the GND planes.
15, 46
GND
22, 24,
27, 30,
31, 34
I, Power Ground reference. GND should be tied to a solid ground plane through a low impedance
path.
Exposed
Pad
PAD
I, Power Connect to GND. The exposed pad at the center of the package should be connected to the
ground plane of the board to enhance thermal and electrical performance of the package.
Serial Management Bus (SMBus) Interface Control Pins
SDA
SDC
CS
18
I, CMOS Data Input. Internally pulled high.
17
I, CMOS Clock Input. Internally pulled high.
16
I, CMOS Chip select. When held high, the equalizer SMBus register is enabled. When held low, the
equalizer SMBus register is disabled. CS is internally pulled low. CS is internally gated with
SDC.
