Ground. 0 V.
Positive Supply Voltage. +1.8 V
Lock Indicator (LVCMOS). This output goes to a logic high when the PLL is
locked to a valid input reference.
Reference Failure Indicator (LVCMOS). A logic high at this output indicates
that the REF input has failed.
Internal Connection. Leave unconnected.
Positive Supply Voltage. +1.8 V
Positive Analog Supply Voltage. +1.8 V
Ground. 0 V.
Internal Connection. Connect to GND.
Reset (LVCMOS, Schmitt Trigger). A logic low at this input resets the device.
On power up, the RST pin must be held low for a minimum of 300 ns after the
power supply pins have reached the minimum supply voltage. When the RST
pin goes high, the device will transition into a Reset state for 3 ms. In the
Reset state all outputs will be forced into high impedance.
Oscillator Master Clock (LVCMOS). For crystal operation, a 20 MHz crystal is
connected from this pin to OSCi. This output is not suitable for driving other
devices. For clock oscillator operation, this pin must be left unconnected.
Oscillator Master Clock (Input). For crystal operation, a 20 MHz crystal is
connected from this pin to OSCo. For clock oscillator operation, this pin must be
connected to a clock source.
Internal Connection. Connect to GND.
Positive Supply Voltage. +3.3 V
Positive Analog Supply Voltage. +3.3 V
Ground. 0 V.
Analog Ground. 0V.
Positive Analog Supply Voltage. +1.8 V
Positive Analog Supply Voltage. +3.3 V
Internal Connection. Leave unconnected.
Clock 8.192 MHz (LVCMOS). This is a 8.192 MHz clock output.
Analog Ground. 0V.
Positive Analog Supply Voltage. +3.3 V
Clock 2.048 MHz (LVCMOS). This is a 2.048 MHz clock output.
Analog Ground. 0V.
Frame Pulse (LVCMOS). This is an 8 kHz frame pulse which marks the
beginning of a 125 us frame. Pulse width is 122 ns.
