SLPN
INPUT - TTL: Serial Loopback enable input. Normal operation when HIGH. When
LOW, Rx+/- is looped back to Tx+/- internally for diagnostic purposes. Refer to Table 2
and related description.

LPNA
LPNB
LPNC
LPND
INPUT - TTL: Loopback Enable Pins. When LPNx is LOW, PLUP/SLPN impact
Channel x. When HIGH, PLUP/SLPN have no effect on Channel x.
R17
ENCDET
INPUT - TTL: Enables SYNCx and word alignment when HIGH. When LOW, keeps
current word alignment and disables SYNCx (always LOW).

B15
SYNCA
SYNCB
SYNCC
SYNCD
OUTPUT - TTL: Comma Detect for Channel x. This output goes HIGH for half of an
RCx1 period to indicate that Rx(0:9) contains a Comma Character (
‘
0011111XXX
’
).
SYNCx will go HIGH only during a cycle when RCX0 is rising. SYNCx is enabled when
ENCDET is HIGH.

CAP0
CAP1
ANALOG: Loop Filter capacitor for the Clock Multiply Unit. Typically 0.1 uF connected
between CAP0 and CAP1. Amplitude is less than 3.3V.
T17
TCK
INPUT - TTL: JTAG Test Clock
D9
TMS
INPUT - TTL: JTAG Test Mode Select
