HSTL_CLK,
HSTL
Differential clock input selected by CLK_SEL. Can be left floating if not
/HSTL_CLK
Input
selected. Floating input, if selected produces an indeterminate output. HSTL
input signal requires external termination 50
to GND.
5, 6
LVPECL_CLK,
LVPECL
Differential clock input selected by CLK_SEL. Can be left floating. Floating
/LVPECL_CLK
Input
input, if selected produces a LOW at the output (internal 75
pull-downs).
Requires external termination. 75k
pull-up.
4
CLK_SEL
LVTTL
Selects HSTL_CLK input when LOW and LVPECL_CLK output when HIGH.
Input
11k
pull-up.
8
OE
LVTTL
Enable input synchronized internally to prevent glitching of the Q0-Q8 and
Input
/Q0-/Q8 outputs. Must be a minimum of three clock periods wide if
synchronous with the CLK inputs and must meet the tS and tH requirements
(refer to AC Electrical Characteristics). If asynchronous, must be a minimum
of four clock periods wide. 11k
pull-up.
31, 29, 27, 23,
Q0–Q8
HSTL
Differential clock outputs from HSTL_CLK when CLK_SEL = LOW and
21, 19, 15, 13,
Output
LVPECL outputs when CLK_SEL = HIGH. HSTL outputs must be terminated
11
with 50
to GND. Q0–Q8 outputs are static LOW when OE = LOW. Unused
output pairs may be left floating.
30, 28, 26, 22,
/Q0–/Q8
HSTL
Differential clock outputs from HSTL_CLK when CLK_SEL = LOW and
20, 18, 14, 12,
Output
LVPECL outputs when CLK_SEL = HIGH. HSTL outputs must be terminated
10
with 50
to GND. /Q0–/Q8 outputs are static HIGH when OE = LOW.
Unused output pairs may be left floating.
