= input with an internal 50 k
pull-down.
Depending on the setting of register bit GCCF[GDRIVER], this output can be programmed to either open drain or push-pull.

Pin Description
Data Upstream
. GCI+ data input.
Data Downstream
. GCI+ data output. Open-drain
output (typical).
80 kHz Receive Clock
. When the TEST pin is asserted, this pin assumes the
alternate function RCLKEN. This output is a buffered version of the internal
80 kHz baud clock that is locked to the received data on the U-interface (or free-
running if the U-interface is inactive).
GCI Data Clock
. Rate defined by GCCF[GRATE(1:0)].
DCL
(K2_512)

O
(O)
K2_512K Clock
. When the TEST pin is asserted, this pin assumes the alternate
function K2_512. This is the 512 kHz internal data clock from the U block, and is
synchronous to the received data on the U-interface.
Programmable Frame Sync 1
. Envelope of channel #0 (GCI mode) or frame
sync pulse for B1 channel (TDM mode). See Table 28.
FS1
(K2_F)
30
O
(O)
K2_Frame Clock
. When the TEST pin is asserted, this pin assumes the alter-
nate function K2_F. This is the 8 kHz frame clock from the U block, and is syn-
chronous to the received data on the U-interface.
Programmable Frame Sync 2
. Frame sync pulse for B2 channel. See Table 28.
FS2
(ILOSS)
34
O
(I
d
)
Insertion Loss
. When the TEST pin is asserted, this pin assumes the alternate
function ILOSS. The ILOSS pin causes the device to continuously transmit an
SN1 pattern. This is useful for performing certain tests such as power spectral
density. Internal 50 k
pull-down.
0: No effect on device operation.
1: U transmitter sends SN1 tone continuously.
