Description
Non-inverting and inverting high speed CML differential inputs of the
deserializer. These inputs are internally terminated.
DS32ELX0124 only. Non-inverting and inverting high speed CML
differential inputs of the deserializer. These inputs are internally
terminated.
DS32ELX0124 only. Retimed serialized high speed output. Non-inverting
and inverting speed CML differential outputs of the deserializer. These
outputs are internally terminated.
Deserializer output clock. RxCLKOUT+/- are the non-inverting and
inverting LVDS recovered clock output pins.
Deserializer output data. RxOUT[0:4]+/- are the non-inverting and
inverting LVDS deserialized output data pins.
DS32ELX0124 only. When held high, retimed serialized high speed
output is enabled.
DS32ELX0124 only. RX_MUX_SEL selects the input of the deserializer.
0 = RxIN0+/- selected
1 = RxIN1+/- selected
DS32ELX0124 only. VOD control. The deserializer loop through output
amplitude can be adjusted by connecting this pin to a pull-down resistor.
The value of the pull-down resistor determines the VOD. See
THROUGH DRIVER LAUNCH AMPLITUDE
DC-balance and Remote Sense pins. See Application section for device
behavior.
Reset pin. When held low, reset the device.
0 = Device Reset
1 = Normal operation
Lock indication output. pin goes low when the deserializer is locked to the
incoming data stream and begins to output data and clock on RxOUT and
RxCLKOUT respectively.
0 = Deserializer locked
1 = Deserializer not locked
SMBus compatible clock.
SMBus compatible data line.
SMBus chip select. When held high, SMBus management control is
enabled.
