Pin Description
Pin #
Name
Description
1GND
Ground. 0V
2VCORE
Positive Supply Voltage. +1.8 VDC nominal
3LOCK
Lock Indicator (Output). This output goes to a logic high when the PLL is frequency
locked to the selected input reference.
4
HOLDOVER
Holdover (Output). This output goes to a logic high whenever the PLL goes into
holdover mode.
5
REF_FAIL0
Reference 0 Failure Indicator (Output). A logic high at this pin indicates that the REF0
reference frequency has exceeded the out-of-range limit set by the APP_SEL pins or that
it is exhibiting abrupt phase or frequency changes.
6
REF_FAIL1
Reference 1 Failure Indicator (Output). A logic high at this pin indicates that the REF1
reference frequency has exceeded the out-of-range limit set by the APP_SEL pins or that
it is exhibiting abrupt phase or frequency changes.
7
REF_FAIL2
Reference 2 Failure Indicator (Output). A logic high at this pin indicates that the REF2
reference frequency has exceeded the out-of-range limit set by the APP_SEL pins or that
it is exhibiting abrupt phase or frequency changes.
8TDO
Test Serial Data Out (Output). JTAG serial data is output on this pin on the falling edge
of TCK. This pin is held in high impedance state when JTAG scan is not enabled.
9TMS
Test Mode Select (Input). JTAG signal that controls the state transitions of the TAP
controller. This pin is internally pulled up to VDD. If this pin is not used then it should be
left unconnected.
10
TRST
Test Reset (Input). Asynchronously initializes the JTAG TAP controller by putting it in the
Test-Logic-Reset state. 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.
11
TCK
Test Clock (Input): Provides the clock to the JTAG test logic. If this pin is not used then it
should be pulled down to GND.
12
VCORE
Positive Supply Voltage. +1.8 VDC nominal
13
GND
Ground. 0V
14
AVCORE
Positive Analog Supply Voltage. +1.8 VDC nominal
15
TDI
Test Serial Data In (Input). JTAG serial test instructions and data are shifted in on this
pin. This pin is internally pulled up to VDD. If this pin is not used then it should be left
unconnected.
16
HMS
Hitless Mode Switching (Input). The HMS input controls phase accumulation during the
transition from Holdover or Freerun mode to Normal mode on the same reference. A logic
low at this pin will cause the ZL30105 to maintain the delay stored in the TIE corrector
circuit when it transitions from Holdover or Freerun mode to Normal mode. A logic high
on this pin will cause the ZL30105 to measure a new delay for its TIE corrector circuit
thereby minimizing the output phase movement when it transitions from Holdover or
Freerun mode to Normal mode.
17
MODE_SEL0
Mode Select 0 (Input). This input combined with MODE_SEL1 determines the mode of
operation, see Table 4 on page 19.
18
MODE_SEL1
Mode Select 1 (Input). See MODE_SEL0 pin description.
