Name
GND
Description
Negative power supply pin, normally 0V
(ground). All analog and digital signals
are referenced to this pin.
Positive power supply input, which must
be +5V
±
5% relative to GND.
The 15.36 MHz Master Clock input, which
requires either a crystal (Note 1) to be
tied between this pin and XTAL2, or a
CMOS logic level clock input from a
stable source. When using a crystal, a
total of 33 pF load capacitance to GND
must also be connected. (Note 2)
The output of the crystal oscillator, which
should be connected to one end of the
crystal, and 33 pF of load capacitance to
GND. (Note 2) If using an external master
Clock via the MCLK pin, leave the XTAL2
pin unconnected.
The Bit Clock pin, which determines the
data shift rate for “B” and “D” channel
data at the digital interface. When NT
mode or TES mode is selected, BCLK is
a TTL/CMOS input which may be any
multiple of 8 kHz from 256 kHz to 4.096
MHz. It need not be synchronous with
MCLK.
When TEM mode is selected, this pin is a
CMOS output at frequency selected by
the Digital Interface Format. This clock is
phase-locked to the received line signal
and is synchronous with the data on B
x
and B
r
