NAME
I/O
FUNCTION
TCLKn
I
Transmitter Clock. A DS3 (44.736MHz
±20ppm), E3 (34.368MHz ±20ppm), or STS-1 (51.840MHz
±20ppm) clock should be applied at this signal. Data to be transmitted is clocked into the device at
TPOS/TDAT and TNEG either on the rising edge of TCLK (TCINV = 0) or the falling edge of TCLK
(TCINV = 1). See Section 7 for additional details.
TPOSn/
TDATn
I
Transmitter Positive AMI/Transmitter Data. When the transmitter is configured to have a bipolar
interface (TBIN = 0), a positive pulse is transmitted on the line when TPOS is high. When the
transmitter is configured to have a binary interface (TBIN = 1), the data on TDAT is transmitted after
B3ZS or HDB3 encoding. TPOS/TDAT is sampled either on the rising edge of TCLK (TCINV = 0) or
on the falling edge of TCLK (TCINV = 1).
TNEGn
I
Transmitter Negative AMI. When the transmitter is configured to have a bipolar interface (TBIN = 0), a
negative pulse is transmitted on the line when TNEG is high. When the transmitter is configured to
have a binary interface (TBIN = 1), TNEG is ignored and should be wired either high or low. TNEG is
sampled either on the rising edge of TCLK (TCINV = 0) or on the falling edge of TCLK (TCINV = 1).
TXPn,
TXNn
O3
Transmitter Analog Outputs. These differential AMI outputs are coupled to the outbound 75
Ω coaxial
cable through a 2:1 step-down transformer (Figure 1-1). These outputs can be tri-stated using the
TTS
pin or the TTS or TPS configuration bits.
TTSn
I
Transmitter Tri-State Enable (Active Low).
TTS tri-states the transmitter outputs (TXP and TXN). This
feature supports applications requiring LIU redundancy. Transmitter outputs from multiple LIUs can be
wire-ORed together, eliminating external switches. The transmitter continues to operate internally
when
TTS is active.
0 = tri-state the transmitter output driver
1 = enable the transmitter output driver
TDMn
O
Transmitter Driver Monitor (Active Low, Open Drain).
TDM reports the status of the transmit driver
monitor. When the transmit driver monitor detects a faulty transmitter,
TDM is driven low. TDM
requires an external pullup to VDD.
TDSAn,
TDSBn
I
Transmitter Data Select. These inputs select the source of the transmit data. See Table 4-F for details.
TLBOn
I
Transmitter Line Build-Out Enable. TLBO indicates cable length for waveform shaping in DS3 and
STS-1 modes. TLBO is ignored for E3 mode and should be wired high or low.
0 = cable length
≥ 225ft
1 = cable length < 225ft
TJAn
I
Transmitter Jitter Attenuator Enable
0 = remove jitter attenuator from the transmitter path
1 = insert jitter attenuator into the transmitter path
(Note that TJA = 1 takes precedence over RJA = 1.)
