Positive Supply. 5.0 volts.
Receive Clock. Recovered 1.544 MHz clock.
Receive Bipolar Data. Recovered bipolar data; updated on the
rising edge of RCLK. Bipolar violations are not corrected.
Loopback Clock. Clock for loopback data. Internally pulled low
by 100K ohm.
Loopback Bipolar Data. Samples on the falling edge of LCLK
if LB is tied high. Internally pulled low by 100K ohm.
Loopback Enable. Tie high to loopback data from the LPOS
and LNEG inputs to RPOS and RNEG; tie low or leave open to
obtain recovered data out of the ALBO circuitry at RPOS and
RNEG. Internally pulled low by 100K ohm.
Receive Carrier Loss. Transitions high when 192 consecutive
zeros have been received at RX+ and RX-; reset on the next
ones occurrence.
Receive Bipolar Violation. Transitions high for a full bit period
when a bipolar violation appears at RX+ and RX-. B8ZS code
words are not reported if B8ZS is tied high.
Lock Indication. High state indicates that the recovery circuit is
phase-and frequency-locked to the signal at RX+ and RX-.
Buffer Limit. Transitions high when the incoming jitter at RX+
and RX- is greater than 120Ulpp.
Disable Jitter Attenuation. Tie high to disable the jitter attenu-
ation circuitry; tie low to enable the jitter attenuation circuitry.
Internally pulled low by 100K ohm.
B8ZS Enable. If tied high, incoming B8ZS code words are de-
coded and replaced with eight zeros. If tied low, B8ZS code
words are not decoded. Internally pulled low by 100K ohm.
Reset. Active low; a high-low-high transition will recenter the
dejitter buffer. Internally pulled high by 100K ohm.
Ground. 0.0 volts.
Receive Analog Input. Connects to T1 line through a 2:1 trans-
former. See Figure 4.
