Receive Clock for Channels 1–16.
The receive data (RPOS/RNEG)
is clocked out on the rising edge of RCLK. If a given receiver is in
power-down mode the RCLK is high impedance. Upon a LOS being
detected, the RCLK is switched from the recovered clock to MCLK.
RCLK can be inverted by the RCLKI register.
MCLK
H12
I
Master Clock.
This is an independent free-running clock that can be
a multiple of 2.048MHz ±50ppm for E1 mode or 1.544MHz ±50ppm
for T1 mode. The clock selection is available by
MC
bits MPS0,
MPS1, FREQS, and PLLE. A multiple of 2.048MHz can be internal
adapted to 1.544MHz and a multiple of 1.544MHz can be internal
adapted to 2.048MHz.

O
Loss-of-Signal Output.
This output goes high when there is no
transition on the received signal over a specified interval. The output
will go low when there is sufficient ones density in the received signal.
The LOS criteria for assertion and desertion criteria are described in
Section
5.5.5
. The LOS outputs can be configured to comply with
T1.231, ITU G.775 or ETSI 300 233.
T1/E1 Clock (TECLK) (Ball E11 only).
This output becomes a T1 or
E1 programmable clock output when enabled by register
MC
. For T1
or E1 frequency selection see register
CCR
.
Clock A (CLKA) (Ball F10 only).
This output becomes a
programmable clock output when enabled by register
MC
. For
frequency options see register
CCR
.
HOST SELECTION
Mode Selection.
This pin is used to select the control mode of the
DS26334:
Low
serial host mode
High
parallel host mode
Motorola Intel Select.
When this pin is low, Motorola mode is
selected. When this pin is high Intel mode is selected.
Chip Select Bar.
This signal must be low during all accesses to the
registers.
