Oscillator Master Clock (CMOS Output).
For crystal operation, a 20MHz crystal is
connected from this pin to OSCi, see Figure 6. For clock oscillator operation, this pin is left
unconnected, see Figure 5.
Oscillator Master Clock (CMOS Input).
For crystal operation, a 20MHz crystal is
connected from this pin to OSCo, see Figure 6. For clock oscillator operation, this pin is
connected to a clock source, see Figure 5.
Frame Pulse ST-BUS 16.384Mb/s (CMO7S Output).
This is an 8kHz 61ns active low
framing pulse, which marks the beginning of an ST-BUS frame. This is typically used for
ST-BUS operation at 16.384Mb/s. See Figure 11.
Frame Pulse ST-BUS 2.048Mb/s (CMOS Output).
This is an 8kHz 244ns active low
framing pulse, which marks the beginning of an ST-BUS frame. This is typically used for
ST-BUS operation at 2.048Mb/s and 4.096Mb/s. See Figure 11.
Frame Pulse ST-BUS 8.192Mb/s (CMOS Output).
This is an 8kHz 122ns active high
framing pulse, which marks the beginning of an ST-BUS frame. This is used for ST-BUS
operation at 8.192Mb/s. See Figure 11.
Clock 1.544MHz (CMOS Output).
This output is used in T1 applications.
Clock 3.088MHz (CMOS Output).
This optional output is used in T1 applications.
Clock 2.048MHz (CMOS Output).
This output is used for ST-BUS operation at 2.048Mb/s.
Clock 4.096MHz (CMOS Output).
This output is used for ST-BUS operation at 2.048Mb/s
and 4.096Mb/s.
