Pin Function
Differential clock input selected by CLK_SEL. Can be left floating if not selected. Floating
input, if selected, produces an indeterminate output. HSTL input signal requires external
termination 50 to GND.
Differential clock input selected by CLK_SEL. Can be left floating. Floating input, if
selected, produces a LOW at the output. Requires external termination. 75k pull-up.
Selects HSTL_CLK input when LOW and LVPECL_CLK output when HIGH. 11k
pull-up. Default condition selects LVPECL_CLK if left open.
Enable input synchronized internally to prevent glitching of the Q0-Q21 and /Q0–/Q21
outputs. Must be a minimum of three clock periods wide if synchronous with the CLK
inputs and must meet the t
section). If asynchronous, must be a minimum of four clock periods wide. 11k pull-up.
Differential clock outputs from HSTL_CLK when CLK_SEL = LOW and LVPECL outputs
when CLK_SEL = HIGH. HSTL outputs must be terminated with 50 to GND. Q0–Q21
outputs are static LOW when OE = LOW. Unused output pairs may be left floating.
Differential clock outputs from HSTL_CLK when CLK_SEL = LOW and LVPECL outputs
when CLK_SEL = HIGH. HSTL outputs must be terminated with 50 to GND. /Q0–/Q21
outputs are static HIGH when OE = LOW. Unused output pairs may be left floating.
