DataOutputSwitching.Dataisoutput
from both PA and PD when left open.
If pin is connected to
DV
CC1
, only PA
is used as output with PB high
impedance. If pin is connected to
DGND1
, only PB is used as output
with PA high impedance.

VOCLP
I
Clamp Voltage
Defines TTL output high level. If left
open the high level is ~ 2.8V.

PS
I
TTL
Power Savings Pin. When left open
or at high level the device operates
normally. When set to low level the
power saving mode enabled.
13
CLK/E
I
PECL/ECL
Clock Input.
14
CLK/NE
I
CLK/E Complementary Input. When
left open, this pin goes to the
threshold potential. Only CLK/E can
be used for operation, but
complementary input is
recommended to attain fast and
stable operation.
48
RESETN/E
I
Reset Input. When the input is set to
low level, the built-in CLK frequency
divider circuit can be reset.
47
RESET/E
I
RESETN/E Complementary Input.
When left open, this pin goes to the
threshold voltage. Only RESETN/E
can be used for operation.
15
CLK/T
I
TTL
Clock input.
46
RESETN/T
I
Reset Input. When left open, this
input goes to high level. When the
input is set to low level, the built-in
CLK frequency divider circuit can be
reset.
44
INV
I
TTL
Data Output Polarity Inversion Input.
When left open, this input goes to
high level. (See Table 1; I/O
Correspondence Table).
