ROVRHD[4]
ROVRHD[3]
ROVRHD[2]
ROVRHD[1]
Output V13
Framer Receive Overhead Indication
(ROVRHD[4:1]). ROVRHD[4:1] is valid
when the S/UNI-QJET is configured as a
DS3, E3, or J2 framer for non-ATM
applications by setting the FRMRONLY bit
in the S/UNI-QJET Configuration 1
Registers. ROVRHD[4:1] will be high
whenever the data on RDATO[4:1]
corresponds to an overhead bit position.
ROVRHD[4:1] is updated on the either the
falling or rising edge of RSCLK[4:1]
depending on the setting of the RSCLKR
bit in the S/UNI-QJET Receive
V10
U8
W4
Configuration register.
RPOHCLK[4] Output W13
Receive PLCP Overhead Clock
(RPOHCLK[4:1]). RPOHCLK[4:1] is active
when PLCP processing is enabled. The
frequency of this signal depends on the
selected PLCP format. RPOHCLK[4:1] is
nominally a 26.7 kHz clock for a DS1
PLCP frame, a 768 kHz clock for a DS3
PLCP frame, a 33.7 kHz clock for an E1
based PLCP frame, or a 576 kHz clock for
a G.751 E3 based PLCP frame.
RPOHCLK[3]
RPOHCLK[2]
RPOHCLK[1]
U10
V7
U5
RPOHFP[4:1] and RPOH[4:1] are updated
on the falling edge of RPOHCLK[4:1].
RSCLK[4]
RSCLK[3]
RSCLK[2]
RSCLK[1]
Framer Recovered Clock (RSCLK[4:1]).
RSCLK[4:1] is valid when the S/UNI-QJET
is configured as a DS3, E3, or J2 framer
for non-ATM applications by setting the
FRMRONLY bit in the S/UNI-QJET
Configuration Register.
RSCLK[4:1] is the recovered clock and
timing reference for RDATO[4:1],
RFPO/RMFPO[4:1], and ROVRHD[4:1].
