IGLOO nano Device Overview
1-8
Revision 17
The inputs of the six CCC blocks are accessible from the FPGA core or from dedicated connections to
the CCC block, which are located near the CCC.
The CCC block has these key features:
Wide input frequency range (fIN_CCC) = 1.5 MHz up to 250 MHz
Output frequency range (fOUT_CCC) = 0.75 MHz up to 250 MHz
2 programmable delay types for clock skew minimization
Clock frequency synthesis (for PLL only)
Additional CCC specifications:
Internal phase shift = 0°, 90°, 180°, and 270°. Output phase shift depends on the output divider
configuration (for PLL only).
Output duty cycle = 50% ± 1.5% or better (for PLL only)
Low output jitter: worst case < 2.5% × clock period peak-to-peak period jitter when single global
network used (for PLL only)
Maximum acquisition time is 300 s (for PLL only)
Exceptional tolerance to input period jitter—allowable input jitter is up to 1.5 ns (for PLL only)
Four precise phases; maximum misalignment between adjacent phases of 40 ps × 250 MHz /
fOUT_CCC (for PLL only)
Global Clocking
IGLOO nano devices have extensive support for multiple clocking domains. In addition to the CCC and
PLL support described above, there is a comprehensive global clock distribution network.
Each VersaTile input and output port has access to nine VersaNets: six chip (main) and three quadrant
global networks. The VersaNets can be driven by the CCC or directly accessed from the core via
multiplexers (MUXes). The VersaNets can be used to distribute low-skew clock signals or for rapid
distribution of high-fanout nets.
I/Os with Advanced I/O Standards
IGLOO nano FPGAs feature a flexible I/O structure, supporting a range of voltages (1.2 V, 1.2 V wide
range, 1.5 V, 1.8 V, 2.5 V, 3.0 V wide range, and 3.3 V).
The I/Os are organized into banks with two, three, or four banks per device. The configuration of these
banks determines the I/O standards supported.
Each I/O module contains several input, output, and enable registers. These registers allow the
implementation of various single-data-rate applications for all versions of nano devices and double-data-
rate applications for the AGLN060, AGLN125, and AGLN250 devices.
IGLOO nano devices support LVTTL and LVCMOS I/O standards, are hot-swappable, and support cold-
sparing and Schmitt trigger.
Hot-swap (also called hot-plug, or hot-insertion) is the operation of hot-insertion or hot-removal of a card
in a powered-up system.
Cold-sparing (also called cold-swap) refers to the ability of a device to leave system data undisturbed
when the system is powered up, while the component itself is powered down, or when power supplies
are floating.
Wide Range I/O Support
IGLOO nano devices support JEDEC-defined wide range I/O operation. IGLOO nano devices support
both the JESD8-B specification, covering both 3 V and 3.3 V supplies, for an effective operating range of
2.7 V to 3.6 V, and JESD8-12 with its 1.2 V nominal, supporting an effective operating range of 1.14 V to
1.575 V.
Wider I/O range means designers can eliminate power supplies or power conditioning components from
the board or move to less costly components with greater tolerances. Wide range eases I/O bank
management and provides enhanced protection from system voltage spikes, while providing the flexibility
to easily run custom voltage applications.
