PIN DESCRIPTION
Pin Number
Pin Name
Type
Pin Function
5, 6
HSTL_CLK,
HSTL
Differential clock input selected by CLK_SEL. Can be left floating if not selected. Floating
/HSTL_CLK
Input
input, if selected, produces an indeterminate output. HSTL input signal requires external
termination 50
to GND.
8, 9
LVPECL_CLK,
LVPECL
Differential clock input selected by CLK_SEL. Can be left floating. Floating input, if
/LVPECL_CLK
Input
selected, produces a LOW at the output. Requires external termination. 75k
pull-up.
7
CLK_SEL
LVTTL
Selects HSTL_CLK input when LOW and LVPECL_CLK output when HIGH. 11k
Input
pull-up. Default condition selects LVPECL_CLK if left open.
11
OE
LVTTL
Enable input synchronized internally to prevent glitching of the Q0-Q21 and /Q0–/Q21
Input
outputs. Must be a minimum of three clock periods wide if synchronous with the CLK
inputs and must meet the t
S and tH requirements (refer to “AC Electrical Characteristics”
section). If asynchronous, must be a minimum of four clock periods wide. 11k
pull-up.
63, 61, 59, 57, 55, 53
Q0–Q21
HSTL
Differential clock outputs from HSTL_CLK when CLK_SEL = LOW and LVPECL outputs
51, 47, 45, 43, 41, 39
Output
when CLK_SEL = HIGH. HSTL outputs must be terminated with 50
to GND. Q0–Q21
37, 35, 31, 29, 27
outputs are static LOW when OE = LOW. Unused output pairs may be left floating.
25, 23, 21, 19, 15
62, 60, 58, 56, 54, 52
/Q0–/Q21
HSTL
Differential clock outputs from HSTL_CLK when CLK_SEL = LOW and LVPECL outputs
50, 46, 44, 42, 40, 38
Output
when CLK_SEL = HIGH. HSTL outputs must be terminated with 50
to GND. /Q0–/Q21
36, 34, 30, 28, 26
outputs are static HIGH when OE = LOW. Unused output pairs may be left floating.
