Table 4-D. Global Pin Descriptions
NAME
I/O
FUNCTION
HIZ
IPU
High-Z Enable Input (Active Low, Open Drain)
0 = tri-state all output pins (Note that the
JTRST pin must be low.)
1 = normal operation
RST
IPU
Reset Input (Active Low, Open Drain, Internal 10k
Ω Pullup to V
DD). When this global asynchronous
reset is pulled low, the internal circuitry is reset and the internal registers (CPU bus mode) are forced
to their default values. The device is held in reset as long as
RST is low. RST should be held low for
at least two master clock cycles.
HW
I
Hardwired Mode Select
0 = CPU bus mode
1 = hardwired mode
See Section 3 for details.
T3MCLK
I
T3 Master Clock. A transmission-quality DS3 (44.736MHz
±20ppm, low jitter) clock should be applied
at this pin. Wiring T3MCLK high forces LIUs in DS3 mode to use TCLK for receiver clock and data
recovery.
E3MCLK
I
E3 Master Clock. A transmission-quality E3 (34.368MHz
±20ppm, low jitter) clock should be applied
at this pin. Wiring E3MCLK high forces LIUs in E3 mode to use TCLK for receiver clock and data
recovery.
STMCLK
I
STS-1 Master Clock. A transmission-quality STS-1 (51.840MHz
±20ppm, low jitter) clock should be
applied at this pin. Wiring STMCLK high forces LIUs in STS-1 mode to use TCLK for receiver clock
and data recovery.
PRBSn
O
PRBS Detector Output. This signal reports the status of the PRBS detector. See Section 8 for further
details.
LLBn,
RLBn
I
Local Loopback Select, Remote Loopback Select
{LLB, RLB} =
00 = no loopback
01 = remote loopback
10 = analog local loopback
11 = digital local loopback
E3Mn
I
E3 Mode Enable
0 = DS3 operation
1 = E3 or STS-1 operation
STSn
I
STS-1 Mode Enable
When E3M = 1,
0 = E3 operation
1 = STS-1 operation
When E3M = 0, STS selects the DS3 AIS pattern.
RBIN
I
Receiver Binary Framer-Interface Enable
0 = Receiver framer interface is bipolar on the RPOS and RNEG pins. The B3ZS/HDB3 decoder is
disabled.
1 = Receiver framer interface is binary on the RDAT pin with the RLCV pin indicating line-code
violations. The B3ZS/HDB3 encoder is enabled.
TBIN
I
Transmitter Binary Framer-Interface Enable
0 = Transmitter framer interface is bipolar on the TPOS and TNEG pins. The B3ZS/HDB3 encoder is
disabled.
1 = Transmitter framer interface is binary on the TDAT pin. (TNEG is ignored and should be wired
low.) The B3ZS/HDB3 encoder is enabled.
RCINV
I
Receiver Clock Invert
0 = RPOS/RDAT and RNEG/RLCV update on the falling edge of RCLK.
1 = RPOS/RDAT and RNEG/RLCV update on the rising edge of RCLK.
TCINV
I
Transmitter Clock Invert
0 = TPOS/TDAT and TNEG are sampled on the rising edge of TCLK.
1 = TPOS/TDAT and TNEG are sampled on the falling edge of TCLK.
MOT
I
Motorola Bus Mode Enable
0 = Intel bus mode
1 = Motorola bus mode
ALE
I
Address Latch Enable. This signal controls a latch on the A[5:0] inputs. In nonmultiplexed bus
applications, ALE should be wired high to make the latch transparent. In multiplexed bus
applications, A[5:0] should be wired to D[5:0]. The falling edge of ALE latches the address.
CS
I
Chip Select (Active Low).
CS must be asserted in order to read or write internal registers.
WR / R/W
I
Write Enable (Active Low) or Read/Write Select. In Intel bus mode (MOT = 0),
WR is asserted to
write internal registers. In Motorola bus mode (MOT = 1), R/
W determines the type of bus
