E1.5o
1.544 MHz Extracted Clock (Output):
This clock is extracted by the device from the
received DS1 signal. It is used internally to clock in data received at RxT and RxR.

. +5V.
5
Received A (Output):
The bipolar DS1 signal received by the device at RxR and RxT is
converted to a unipolar format and output at this pin.

RxT
RxR
Receive Tip and Ring Inputs:
Bipolar split phase inputs designed to be connected
directly to the input transformer. Impedance to ground is approximately 1k
.
Impedance between pins=430
.

RxB
Received B (Output):
The bipolar DS1 signal received by the device at RxR and RxT is
converted to a unipolar format and output at this pin.
9
NC
No Connection.
10
CSTi1
Control ST-BUS Input #1:
A 2048 kbit/s serial control stream which carries 24 per-
channel control words.
11
CSTi0
Control ST-BUS Input #0:
A 2048 kbit/s serial control stream that contains 24 per
channel control words and two master control words.
12
E8Ko
8 kHz Extracted Clock (Output):
This is an 8 kHz output generated by dividing the
extracted 1.544 MHz clock by 193 and aligning it with the received DS1 frame. The 8
kHz signal can be used for synchronizing system clocks to the extracted 1.544 MHz
clock. When digital loopback is enabled, the 8kHz is derived from C1.5.
13
XCtl
External Control (Output):
This is an uncommitted external output pin which is set or
reset via bit 3 in Master Control Word 1 on CSTi0. The state of XCtl is updated once per
frame.
14
XSt
External Status (Schmitt Trigger Input):
The state of this pin is sampled once per
frame and the status is reported in bit 5 of Master Status Word 2 on CSTo.
15
CSTo
Control ST-BUS Output:
This is a 2048 kbit/s serial control stream which provides the
24 per-channel status words, and two master status words.
