TYPE
DESCRIPTION
6
NC
-
No Connect. No internal connection. This pin can be tied to either
VSS or VDD, or it can be floated.
7
RYEL
O
Receive Yellow Alarm. Transitions high when yellow alarm
detected; goes low when alarm clears.
8
RLINK
O
Receive Link Data. Updated with extracted FDL data one RCLK
before start of odd frames (193E) and held until next update.
Updated with extracted S-bit data one RCLK before start of even
frames (193S) and held until next update.
9
RLCLK
O
Receive Link Clock. 4 kHz demand clock for RLINK.
10
RCLK
I
Receive Clock. 1.544 MHz primary clock.
11
RCHCLK
O
Receive Channel Clock. 192 kHz clock; identifies time slot
(channel) boundaries.
12
RSER
O
Receive Serial Data. Received NRZ serial data; updated on rising
edges of RCLK.
13
NC
-
No Connect. No internal connection. This pin can be tied to either
VSS or VDD, or it can be floated.
15
RFSYNC
O
Receive Frame Sync. Extracted 8 kHz clock, one RCLK wide; F-
bit position in each frame.
16
RMSYNC
O
Receive Multiframe Sync. Extracted multiframe sync; positive-
going edge indicates start of multiframe; 50% duty cycle.
17
RABCD
O
Receive ABCD Signaling. Extracted signaling data output; valid
for each channel in signaling frames. In non-signaling frames,
RABCD outputs the LSB of each channel word.
18
ESIGFR
O
Receive Signaling Frame. High during signaling frames; low
during non-signaling frames (and during resync).
19
RSIGSEL
O
Receive Signaling Select. In 193E framing, a .667 kHz clock that
identifies signaling frames A and C; a 1.33 kHz clock in 193S.
21
RST
I
Reset. A high-low transition clears all internal registers and resets
counters. A high-low-high transition initiates a resync.
22
23
RPOS
RNEG
I
Receive Bipolar Data Inputs. Sampled on falling of RCLK. Tie
together to receive NRZ data and disable bipolar violation
monitoring circuitry.
24
RCL
O
Receive Carrier Loss. High if 192 consecutive 0s appear at RPOS
and RNEG; goes low upon seeing 12.5% one’s density.
25
RBV
O
Receive Bipolar Violation. High during accused bit time at RSER.
If bipolar violation detected, low otherwise.
26
RFER
O
Receive Frame Error. High during F-bit time when FT or FS
errors occur (193S), or when FPS or CRC errors occur (193E). Low
during resync.
27
RLOS
O
Receive Loss of Sync. Indicates sync status; high when internal
resync is in progress, low otherwise.
