PIN DESCRIPTIONS
/LOOP – TTL Input
Loop Back Select. This input is used to select the input
data stream source that the Receive PLL uses for clock
and data recovery. When the /LOOP input is HIGH, the
Receive input data stream (RIN
±
) is used for clock and
data recovery. When /LOOP is LOW, the Transmit input
data stream (TSER
±
) is used by the Receive PLL for clock
and data recovery. When in Loop-back testing mode, /LOOP
input asserted low, the Receive PLL is always turned-on
internally regardless of the CD input signal level status.
This allows the Recovered Serial Data outputs (RSER
±
) to
receive data stream from the Transmit serial data inputs
(TSER
±
).
MODE – 3 Level Input
Frequency Mode Select. This three-level input selects
the frequency range for the clock and data recovery receive
PLL and the frequency multiplier transmit PLL. When the
input is held PECL HIGH (V
CC
–
0.9 typ.), the two PLLs
operate at the SONET (SDH) STS-3 (STM-1) line rate of
155.52MHz. When this input is held TTL LOW (connected
to GND), the two PLLs operate at one SONET STS-1 line
rate of 51.84MHz. The REFCLK
±
frequency in both operating
modes is 1
8 of the operating frequency. When the MODE
input is ECL LOW (V
CC
–
1.7 typ), the device enters into
test mode, the TSER
±
inputs substitue for the internal PLL
VCO for use in factory testing.
