ESCRIPTION

E3CLK
I
E3 Clock Input (34.368 MHz ± 20 ppm):
If any of the channels is configured in E3 mode, a reference clock 34.368 MHz
is applied on this pin.
N
OTE
:
In single frequency mode, this reference clock is not required.
G16
DS3CLK
I
DS3 Clock Input (44.736 MHz ± 20 ppm):
If any of the channels is configured in DS3 mode, a reference clock 44.736
MHz. is applied on this pin.
N
OTE
:
In single frequency mode, this reference clock is not required.
C16
STS-1CLK/
12M
I
STS-1 Clock Input (51.84 MHz ± 20 ppm):
If any of the channels is configured in STS-1 mode, a reference clock 51.84
MHz is applied on this pin..
In Single Frequency Mode, a reference clock of 12.288 MHz ± 20 ppm is con-
nected to this pin and the internal clock synthesizer generates the appropriate
clock frequencies based on the configuration of the channels in E3, DS3 or
STS-1 modes.
L15
SFM_EN
I
Single Frequency Mode Enable:
Tie this pin “High” to enable the Single Frequency Mode. A reference clock of
12.288 MHz ± 20 ppm is applied.
In the Single Frequency Mode (SFM) a low jitter output clock is provided for
each channel if the CLK_EN bit is set thus eliminating the need for a separate
clock source for the framer.
Tie this pin “Low” if single frequency mode is not selected. In this case, the
appropriate reference clocks must be provided.

OTE

This pin is internally pulled down

Clock output for channel 2
Clock output for channel 3
Clock output for channel 4
Clock output for channel 5
Low jitter clock output for each channel based on the mode selection (E3,DS3
or STS-1) if the CLKOUTEN_n bit is set in the control register.
This eliminates the need for a separate clock source for the framer.
N
OTES
:
1. The maximum drive capability for the clockouts is 16 mA.
2. This clock out is available both in SFM and non-SFM modes.
