DESCRIPTION

TDDC8

LVCMOS

Transmit data, K-generator channels C and D. In multiplexed channel mode, when CODE

input

= low, this terminal is the 9th bit of a 10-bit word to be transmitted. When CODE = high, this

terminal acts as the K-character indicator. When TDDC8 = high, the data on TDDC[7:0] is

encoded into a K-character.

In nibble interface mode, when CODE = low, this terminal is the 4th and 9th bits of a 10-bit

word to be transmitted on channel D. When CODE = high, this terminal acts as the

K-character indicator for channel D.

In independent channel mode, the transmit clock that latches this input is TCLKD. In all

other modes the transmit clock is TCLKB.

TDDC9

LVCMOS

Transmit data channels C and D. When CODE = low, this terminal is the 10th bit of a 10-bit

input with

word. When CODE = high, this terminal should be left floating or tied low to ground.

P/D

In independent channel mode, the transmit clock that latches this input is TCLKD. In all

other modes, the transmit clock is TCLKB.

TDFE[7:0]

B7, A7, B6,

LVCMOS

Transmit data channels E and F. The parallel data is clocked into the transceiver on the

A6, B5, A5,

input

rising and falling edges of the transmit clock and transmitted as a serial stream with bit 0

B4, A4

sent as the first bit.

In independent channel mode, the transmit clock that latches this input is TCLKF. In all

other modes, the transmit clock is TCLKB.

In multiplexed channel mode, data for channel F is aligned to the rising edge of the

transmit clock and data for channel E is aligned to its falling edge.

In nibble interface mode, data is input least-significant nibble first, aligned to the falling

edge of the transmit clock, followed by the most-significant nibble aligned to the rising edge

of the transmit clock. Channel E data is input on TDFE[4:0] and channel F on TDFE[9:5].

When CODE = high, TDDC3 acts as the K-character indicator for channel E.

TDFE8

LVCMOS

Transmit data, K-generator channels E and F. In multiplexed channel mode, when CODE =

input

low, this terminal is the 9th bit of a 10-bit word to be transmitted. When CODE = high, this

terminal acts as the K-character indicator. When TDFE8 = high, the data on TDFE[7:0] is

encoded into a K-character.

In nibble interface mode, when CODE = low, this terminal is the 4th and 9th bits of a 10-bit

word to be transmitted on channel F. When CODE = high, this terminal acts as the

K-character indicator for channel F.

In independent channel mode, the transmit clock that latches this input is TCLKF. In all

other modes the transmit clock is TCLKB.

TDFE9

LVCMOS

Transmit data channels E and F. When CODE = low, this terminal is the 10th bit of a 10-bit

input with

word. When CODE = high, this terminal should be left floating or tied low to ground.

P/D

In independent channel mode, the transmit clock that latches this input is TCLKF. In all

other modes, the transmit clock is TCLKB.

TDHG[7:0]

B12, A12, B11,

LVCMOS

Transmit data channels G and H. The parallel data is clocked into the transceiver on the

A11, B10, A10,

input

rising and falling edges of the transmit clock and transmitted as a serial stream with bit 0

B9, A9

sent as the first bit.

In independent channel mode, the transmit clock that latches this input is TCLKD. In all

other modes, the transmit clock is TCLKB.

In multiplexed channel mode, data for channel H is aligned to the rising edge of the

transmit clock and data for channel G is aligned to its falling edge.

In nibble interface mode, data is input least-significant nibble first, aligned to the falling

edge of the transmit clock, followed by the most-significant nibble aligned to the rising edge

of the transmit clock. Channel G data is input on TDHG[4:0] and channel F on TDHG[9:5].

When CODE = high, TDHG3 acts as the K-character indicator for channel G.

TDHG8

A13

LVCMOS

Transmit data, K-generator channels G and H. In multiplexed channel mode, when CODE

input

= low, this terminal is the 9th bit of a 10-bit word to be transmitted. When CODE = high, this

terminal acts as the K-character indicator. When TDHG8 = high, the data on TDHG[7:0] is

encoded into a K-character.

In nibble interface mode, when CODE = low, this terminal is the 4th and 9th bits of a 10-bit

word to be transmitted on channel H. When CODE = high, this terminal acts as the

K-character indicator for channel H.

In independent channel mode, the transmit clock that latches this input is TCLKH. In all

other modes, the transmit clock is TCLKB.
