Zarlink Semiconductor Inc.
21
C19o
Clock 19.44 MHz (Output). This CMOS output is used in SONET/SDH applications.
This clock output pad includes a Schmitt input which serves as a PLL feedback path;
proper transmission-line termination should be applied to maintain reflections below
Schmitt trigger levels.
22
AGND
Analog Ground. 0V
23
AVDD
Positive Analog Supply Voltage. +3.3 VDC nominal
24
F8ko
Frame Pulse (Output). This is an CMOS 8 kHz active high 31 ns framing pulse, which
marks the beginning of a 125
μs frame.
This clock output pad includes a Schmitt input which serves as a PLL feedback path;
proper transmission-line termination should be applied to maintain reflections below
Schmitt trigger levels.
25
AGND
Analog Ground. 0V
26
REF_SEL
Reference Select 0 (Input/Output). As an input REF_SEL selects the reference input
that is used for synchronization; See Table 4.
0: REF0
1: REF1
This pin is internally pulled down to GND.
27
REF0
Reference (Input). This is one of two (REF0 and REF1) input reference sources used for
synchronization. One of seven possible frequencies may be used: 2 kHz, 8 kHz,
1.544 MHz, 2.048 MHz, 8.192 MHz,16.384 MHz or 19.44 MHz. This pin is internally
pulled down to GND.
28
REF1
Reference (Input). See REF0 pin description.
29
OOR_SEL
Out Of Range Selection (Input). This input selects the frequency acceptance limits of
the reference monitor: See Table 2.
0: 40 - 52 ppm
1: 64 - 83 ppm
30
IC
Internal Connection. Connect this pin to GND.
31
VDD
Positive Supply Voltage. +3.3 VDC nominal.
32
TIE_CLR
TIE Circuit Reset (Input). A logic low at this input resets the Time Interval Error (TIE)
correction circuit resulting in a realignment of input phase with output phase.
33
IC
Internal Connection. Package E-pad, this pin is internally connected to device GND, it
can be left unconnected or it can be connected to GND.
