Noninverting LVDS Parallel Clock Input. Connect the incoming parallel-clock signal to the
PCLKI inputs. Note that data is updated on the positive transition of the PCLKI signal.
Inverting LVDS Parallel Clock Input. Connect the incoming parallel-clock signal to the PCLKI
inputs. Note that data is updated on the positive transition of the PCLKI signal.
Noninverting LVDS Parallel Data Inputs. Data is clocked on the PCLKI positive transition.
Inverting LVDS Parallel Data Inputs. Data is clocked on the PCLKI positive transition.
Noninverting LVDS Parallel Clock Output. Use positive transition of PCLKO to clock the
overhead management circuit.
Inverting LVDS Parallel Clock Output. Use positive transition of PCLKO to clock the over-
head management circuit.
Noninverting LVDS Reference Clock Input. Connect an LVDS-compatible crystal refer-
ence clock to the RCLK inputs.
Inverting LVDS Reference Clock Input. Connect an LVDS-compatible crystal reference
clock to the RCLK inputs.
Reference Clock Rate Programming Pin:
CLKSET = V
CLKSET = Open: Reference Clock Rate = 77.76MHz
CLKSET = 20kΩ to GND: Reference Clock Rate = 51.84MHz
CLKSET = GND: Reference Clock Rate = 38.88MHz
Filter Capacitor Input. Connect a 330nF capacitor between FIL+ and FIL-.
Filter Capacitor Input. Connect a 330nF capacitor between FIL+ and FIL-.
