Function
Ingress Clocks (ICLK[1:28]). The Ingress Clocks are
active when the external signaling interface is disabled.
Each ingress clock is optionally a smoothed (jitter
attenuated) version of the associated receive clock
from the DS3 multiplexer. When the Clock Master:
NxChannel mode is active, ICLK[x] is a gapped version
of the smoothed receive clock. When Clock Master:
Full T1/E1 mode is active, IFP[x] and ID[x] are updated
on the active edge of ICLK[x]. When the Clock Master:
NxDS0 mode is active, ID[x] is updated on the active
edge of ICLK[x].
Ingress Signaling (ISIG[1:28]). When the Clock
Slave: External Signaling mode is enabled, each
ISIG[x] contains the extracted signaling bits for each
channel in the frame, repeated for the entire
superframe. Each channel’s signaling bits are valid in
bit locations 5,6,7,8 of the channel and are channel-
aligned with the ID[x] data stream. ISIG[x] is updated
on the active edge of the common ingress clock,
CICLK.
In E1 mode only ICLK[1:21] and ISIG[1:21] are used.
ICLK[1]/ISIG[1] shares a pin with the DS3 system
interface signal RGAPCLK/RSCLK.
Ingress Frame Pulse (IFP[1:28]). The IFP[x] outputs
are intended as timing references.
IFP[x] indicates the frame alignment or the superframe
alignment of the ingress stream, ID[x].
When Clock Master: Full T1/E1 mode is active, IFP[x]
is updated on the active edge of the associated
ICLK[x]. When Clock Master: NxDS0 mode is active,
ICLK[x] is gapped during the pulse on IFP[x]. When
the Clock Slave ingress modes are active, IFP[x] is
updated on the active edge of CICLK. I the Clear
