Pin Definition
CLK0, CLK0
CLK1, CLK1
LVPECL Input
LVPECL Input
Differential PLL clock reference (CLK0 pulldown, CLK0 pullup)
Differential PLL clock reference (CLK1 pulldown, CLK1 pullup)
Ext_FB, Ext_FB
LVPECL Input
Differential PLL feedback clock (Ext_FB pulldown, Ext_FB pullup)
Qa0:1, Qa0:1
LVPECL Output
Differential 1x output pairs. Connect one QAx pair to Ext_FB.
Qb0:2, Qb0:2
LVPECL Output
Differential 2x output pairs
Inp0bad
LVCMOS Output
Indicates detection of a bad input reference clock 0 with respect to the feedback signal. The output
is active HIGH and will remain HIGH until the alarm reset is asserted
Inp1bad
LVCMOS Output
Indicates detection of a bad input reference clock 1 with respect to the feedback signal. The output
is active HIGH and will remain HIGH until the alarm reset is asserted
Clk_Selected
LVCMOS Output
‘0’ if clock 0 is selected, ‘1’ if clock 1 is selected
Alarm_Reset
LVCMOS Input
‘0’ will reset the input bad flags and align Clk_Selected with Sel_Clk. The input is “one--shotted”
(50k
pullup)
Sel_Clk
LVCMOS Input
‘0’ selects CLK0, ‘1’ selects CLK1 (50k
pulldown)
Manual_Override
LVCMOS Input
‘1’ disables internal clock switch circuitry (50k
pulldown)
PLL_En
LVCMOS Input
‘0’ bypasses selected input reference around the phase--locked loop (50k
pullup)
MR
LVCMOS Input
‘0’ resets the internal dividers forcing Q outputs LOW. Asynchronous to the clock (50k
pullup)
