OUTPUTS
BRD
± [Buffered Recovered Data] – Differential CML Output
The signal is either a buffered RDIN
± or RDOUTC±,
depending on the state of the BRDMX input. This allows a
user to selectively bypass the CDR or not, as warranted by
architecture. This CML output has a voltage swing of 400mV
loaded.
LFIN [Link Fault Indicate] – O.C. TTL Output
This output indicates the status of the input data stream
RDIN. Active HIGH indicates that the internal clock recovery
PLL has locked onto the incoming data stream. LFIN will go
HIGH if CD is HIGH and RDIN is within the frequency range
of the Receive PLL (as per ALRSEL). LFIN is an
asynchronous output.
RDOUTE
± [Receive Data Out] – Differential PECL Output
These ECL 100K outputs (+3.3V referenced) represent
the recovered data from the input data stream (RDIN). It is
specified on the rising edge of RCLK.
RDOUTC
± [Receive Data Out] – Differential CML Output
This is the CML version of RDOUTE
±.
RCLKE
± [Receive Clock Out] – Differential PECL Output
These ECL 100K outputs (+3.3V referenced) represent
the recovered clock used to sample the recovered data
(RDOUT).
RCLKC
± [Receive Clock Out] – Differential CML Output
This is the CML version of RCLKE
±.
TCLKE
± [Transmit Clock Out] – Differential PECL Output
These ECL 100K outputs (+3.3V referenced) represent
either the recovered clock (CLKSEL = HIGH) used to sample
the recovered data (RDOUT) or the transmit clock of the
frequency synthesizer (CLKSEL = LOW).
TCLKC
± [Transmit Clock Out] – Differential CML Output
This is the CML version of TCLKE
±.
PLLSN+, PLLSN– [Clock Synthesis Loop Filter]
External loop filter pins for the clock synthesis narrow
band PLL.
PLLSW+, PLLSW– [Clock Synthesis Loop Filter]
External loop filter pins for the clock synthesis wide band
PLL.
PLLRN+, PLLRN– [Clock Recovery Loop Filter]
External loop filter pins for the clock recovery narrow
band PLL.
PLLRW+, PLLRW– [Clock Recovery Loop Filter]
External loop filter pins for the clock recovery wide band
PLL.
