LVCMOS CLOCK GENERATOR
Table 1. Pin Descriptions
NOTE: Pulldown refers to internal input resistors. See Table 2, Pin Characteristics, for typical values.
Number
Name
Type
Description
1, 13, 17, 20, 24
GND
Power
Power supply ground.
2
nQ5
Output
Single-ended clock output (phase is inverted with respect to other outputs).
LVCMOS/LVTTL interface levels
3, 15, 22, 27
VDD
Power
Positive power supply pins.
4
OE/nRST
Input
Output enable and asynchronous reset. Resets all outputs. Logic LOW, the
outputs are in a high impedance state. Logic HIGH enables all outputs.
Internally a Power On reset circuit will ensure that the nQ5 output is inverted
relative to Q[4:0]. If OE/nRST is pulsed low, it must be held low for a minimum
of 10 ns for a complete reset operation. This reset may be applied
asynchronously to the input reference.
5
FEEDBACK
Input
PLL feedback input which is connected to one of the clock outputs to close the
PLL feedback loop. LVCMOS/LVTTL interface levels.
6
REF_SEL
Input
Input reference clock select. Logic LOW selects the SYNC0.
Logic HIGH selects the SYNC1 input as the PLL reference input.
LVCMOS/LVTTL interface levels.
7,
11
SYNC0,
SYNC1
Input
Single-ended reference clock inputs. LVCMOS/LVTTL interface levels.
8
AVDD
Power
Positive power supply for the PLL.
9
nPE
Input
Pulldown
Output phase synchronization. In PLL mode (PLL_EN = HIGH) and when logic
LOW, the rising edges of the outputs (2XQ, Q0:Q4, Q/2) are synchronized to
the rising edge of the selected reference clock (SYNCn).
In PLL mode (PLL_EN = HIGH) and when logic HIGH, the falling edges of the
outputs (2XQ, Q0:Q4, Q/2) are synchronized to the falling edge of the selected
reference clock (SYNCn). LVCMOS/LVTTL interface levels.
10
AGND
Power
Power supply ground for the PLL. Internally connected to GND.
12
FREQ_SEL
Input
Frequency select. Logic LOW level inserts a divide-by-2 into the PLL output
and feedback path. Logic HIGH inserts a divide-by-1 into the PLL output and
feedback path. LVCMOS/LVTTL interface levels.
14, 16,
21, 23, 28
Q0, Q1,
Q2, Q3, Q4
Output
Single-ended clock outputs. LVCMOS/LVTTL interface levels.
18
PLL_EN
Input
PLL enable. Enable and disables the PLL. Logic HIGH enables the PLL. Logic
LOW disables the PLL and the input reference signal is routed to the output
dividers (PLL bypass). LVCMOS/LVTTL interface levels.
19
LOCK
Output
PLL lock indication output. Logic HIGH indicates PLL lock. Logic LOW indicates
PLL is not locked. LVCMOS/LVTTL interface levels.
25
Q/2
Output
Single-ended clock output. LVCMOS/LVTTL interface levels.
26
2XQ
Output
Single-ended clock output. LVCMOS/LVTTL interface levels.
