DESCRIPTION
Digital Power Supply. Apply -5V for
PECL and TTL input.
No Connect Pin.
Clock Input.
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.
Reset Input. When the input is set to
low level, the built-in CLK frequency
divider circuit can be reset.
RESETN/E Complementary Input.
When left open, this pin goes to the
threshold voltage. Only RESETN/E
can be used for operation.
Clock input.
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.
1.5V
Data Output Polarity Inversion Input.
When left open, this input goes to
high level. (See Table 1; I/O
Correspondence Table).
