IC
IEEE1149.1a Test Clock Signal (5 V tolerant input). Input clock for the JTAG
test logic. If not used, this pin should be pulled up to VDD.
IEEE1149.1a Reset Signal (3.3 V input). Asynchronous reset for the JTAG
TAP controller. This pin should be pulsed low on power-up to ensure that the
device is in the normal functional state. This pin is internally pulled up to VDD.
If this pin is not used then it should be connected to GND.
IEEE1149.1a Test Data Input (3.3 V input). Input for JTAG serial test
instructions and data. This pin is internally pulled up to VDD. If not used, this
pin should be left unconnected.
No internal bonding Connection. Leave unconnected.
No internal bonding Connection. Leave unconnected.
Primary Reference Out of Range (Output). Logic high at this pin indicates
that the Primary Reference is off the PLL centre frequency by more than
±12 ppm. See PRIOR pin description in Section 4.2 on page 17 for details.
Clock 1.544 MHz (CMOS tristate output). This output provides a 1.544 MHz
DS1 rate clock.
Clock 6.312 MHz (CMOS tristate output). This output provides a 6.312 MHz
DS2 rate clock.
Internal Connection. Connect this pin to Ground.
Ground
Clock 19.44 MHz (CMOS tristate output). This output provides a 19.44 MHz
clock.
Reference Source Select (Input). A logic low selects the PRI (primary)
reference source as the input reference signal and logic high selects the SEC
(secondary) input. The logic level at this input is sampled at the rising edge of
F8o. This pin is internally pulled down to GND.
Reference Alignment (Input). In Hardware Control pulling this pin low for
250 µs initiates phase realignment between the input reference and the
generated output clocks. See Section 3.2.4 on page 11 for details. This pin
should never be tied low permanently. Internally this pin is pulled down to
GND.
Positive Power Supply
No internal bonding Connection. Leave unconnected.
Clock 20 MHz (5 V tolerant input). This pin is the input for the 20 MHz Master
Clock Oscillator. The clock oscillator should be connected directly (not AC
coupled) to the C20i input and it must supply clock with duty cycle that is not
worse than 40/60%.
