PIN DESCRIPTION
Table 1: Pin Description
Name
Pin No.
I/O
Type
Description 1
Global Control Signal
OSCI
10
I
CMOS
OSCI: Crystal Oscillator Master Clock
A nominal 12.8000 MHz clock provided by a crystal oscillator is input on this pin. It is the
master clock for the device.
FF_SRCSW
18
I
pull-down
CMOS
FF_SRCSW: External Fast Selection Enable
During reset, this pin determines the default value of the EXT_SW bit (b4, 0BH) 2. The
EXT_SW bit determines whether the External Fast Selection is enabled.
High: The default value of the EXT_SW bit (b4, 0BH) is ‘1’ (External Fast selection is
enabled);
Low: The default value of the EXT_SW bit (b4, 0BH) is ‘0’ (External Fast selection is dis-
abled).
After reset, this pin selects an input clock pair for the T0 DPLL if the External Fast selection is
enabled:
High: Pair IN1 / IN3 is selected.
Low: Pair IN2/ IN4 is selected.
After reset, the input on this pin takes no effect if the External Fast selection is disabled.
MS/SL
99
I
pull-up
CMOS
MS/SL: Master / Slave Selection
This pin, together with the MS_SL_CTRL bit (b0, 13H), controls whether the device is config-
ured as the Master or as the Slave. Refer to Chapter 3.14 Master / Slave Configuration for
details.
The signal level on this pin is reflected by the MASTER_SLAVE bit (b1, 09H).
SONET/SDH
100
I
pull-down
CMOS
SONET/SDH: SONET / SDH Frequency Selection
During reset, this pin determines the default value of the IN_SONET_SDH bit (b2, 09H):
High: The default value of the IN_SONET_SDH bit is ‘1’ (SONET);
Low: The default value of the IN_SONET_SDH bit is ‘0’ (SDH).
After reset, the value on this pin takes no effect.
RST
74
I
pull-up
CMOS
RST: Reset
A low pulse of at least 50 s on this pin resets the device. After this pin is high, the device will
still be held in reset state for 500 ms (typical).
Frame Synchronization Input Signal
EX_SYNC1
45
I
pull-down
CMOS
EX_SYNC1: External Sync Input 1
A 2 kHz, 4 kHz or 8 kHz signal is input on this pin.
Input Clock
IN1
46
I
pull-down
CMOS
IN1: Input Clock 1
A 2 kHz, 4 kHz, N x 8 kHz 3, 1.544 MHz (SONET) / 2.048 MHz (SDH), 6.48 MHz, 19.44 MHz,
25.92 MHz, 38.88 MHz, 51.84 MHz, 77.76 MHz or 155.52 MHz clock is input on this pin.
IN2
47
I
pull-down
CMOS
IN2: Input Clock 2
A 2 kHz, 4 kHz, N x 8 kHz 3, 1.544 MHz (SONET) / 2.048 MHz (SDH), 6.48 MHz, 19.44 MHz,
25.92 MHz, 38.88 MHz, 51.84 MHz, 77.76 MHz or 155.52 MHz clock is input on this pin.
IN3_POS
IN3_NEG
40
41
I
PECL/LVDS
IN3_POS / IN3_NEG: Positive / Negative Input Clock 3
A 2 kHz, 4 kHz, N x 8 kHz 3, 1.544 MHz (SONET) / 2.048 MHz (SDH), 6.48 MHz, 19.44 MHz,
25.92 MHz, 38.88 MHz, 51.84 MHz, 77.76 MHz, 155.52 MHz, 311.04 MHz or 622.08 MHz
clock is differentially input on this pair of pins. Whether the clock signal is PECL or LVDS is
automatically detected.
IN4_POS
IN4_NEG
42
43
I
PECL/LVDS
IN4_POS / IN4_NEG: Positive / Negative Input Clock 4
A 2 kHz, 4 kHz, N x 8 kHz 3, 1.544 MHz (SONET) / 2.048 MHz (SDH), 6.48 MHz, 19.44 MHz,
25.92 MHz, 38.88 MHz, 51.84 MHz, 77.76 MHz, 155.52 MHz, 311.04 MHz or 622.08 MHz
clock is differentially input on this pair of pins. Whether the clock signal is PECL or LVDS is
automatically detected.
