Reset (Input). 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 clock and frame pulse outputs will be forced
into high impedance.
Oscillator Master Clock (Output). 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. Leave unconnected.
Ground. 0 V
Application Selection 1 (Input). This input combined with APP_SEL0 selects the
application that the ZL30105 is optimized for, see Table 1 on page 20.
Positive Supply Voltage. +3.3 V
Output Selection 2 (Input). This input selects the signals on the combined output clock
and frame pulse pins, see Table 3 on page 21.
Output Selection 1 (Input). This input combined with OUT_SEL0 selects the signals on
the combined output clock pin C6/8.4/34/44o, see Table 3 on page 21.
Output Selection 0 (Input). See OUT_SEL1 description.
Positive Analog Supply Voltage. +3.3 V
in DS2, E2, E3 or DS3 applications. The output frequency is selected via the OUT_SEL1
and OUT_SEL0 pins, see Table 3 on page 21.
Clock 3.088 MHz (Output). This output is used in DS1 applications.
Clock 1.544 MHz (Output). This output is used in DS1 applications.
This clock output pad includes a Schmitt input which serves as a PLL feedback path;
proper transmission-line termination should be applied to maintain reflections below
Schmitt trigger levels.
Analog Ground. 0 V

Positive Analog Supply Voltage. +3.3 V
Multi Frame Pulse (Output). This is a 2 kHz 51 ns active high framing pulse, which
marks the beginning of a multi frame.
Clock 19.44 MHz (Output). This output is used in SDH applications.
