Transmit Data for Channel B. Parallel data on this bus is clocked in on the rising edge
of TCLKA, TCLKB or REFCLK. (See Table 1.)
DNB
TTL
I
R16
DATA_NOT. When Low, data present on DINB[0:7] is 8B/10B encoded and transmit-
ted serially. When High, special character/sequences are generated as indicated in
Table 2.
KGENB
TCLKB
TTL
TTL
I
I
T16
R13
K-Character Generation. KGENB High causes the data on DINB[0:7] to be encoded
into a K-Character. (See Table 2.)
Transmit Data Clock B. When TMODE is High, this signal is used to clock Data on
DINB[0:7], KGENB, and DNB into the S2004. =When TMODE is Low, TCLKB is
ignored. When CH_LOCK HIGH, TCLKB must be tied Low.

Transmit Data for Channel C. Parallel data on this bus is clocked in on the rising
edge of TCLKA, TCLKC, or REFCLK. (See Table 1.)
DNC
TTL
I
N17
DATA_NOT. When Low, data present on DINC[0:7] is 8B/10B encoded and transmit-
ted serially. When High, special character/sequences are generated as indicated in
Table 2.
KGENC

P17
P15
K-Character Generation. KGENC High causes the data on DINC[0:7] to be encoded
into a K-Character. (See Table 2.)
Transmit Data Clock C. When TMODE is High, this signal is used to clock Data on
DINC[0:7], KGENC, and DNC into the S2004. When TMODE is Low, TCLKC is
ignored.

J16
DATA_NOT, When Low, data present on DIND[0:7] is 8B/10B encoded and transmit-
ted serially. When High, special character/sequences are generated as indicated in
Table 2.
KGEND
K17
K-Character Generation. KGEND High causes the data on DIND[0:7] to be encoded
into a K-Character. (See Table 2.)
