SIV54001-2.1
Electrical Characteristics
This chapter covers the electrical characteristics for Stratix IV devices.
Operating Conditions
When Stratix® IV devices are implemented in a system, they are rated according to a
set of defined parameters. To maintain the highest possible performance and
reliability of Stratix IV devices, system designers must consider the following
operating requirements. Stratix IV devices are offered in both commercial and
industrial grades. Commercial devices are offered in -2 (fastest), -2x, -3, and -4 speed
grades.
Absolute Maximum Ratings
Absolute maximum ratings define the maximum operating conditions for Stratix IV
devices. The values are based on experiments conducted with the devices and
theoretical modeling of breakdown and damage mechanisms. The functional
operation of the device is not implied at these conditions.
1
Conditions beyond those listed in Table 1–1 and Table 1–2 may cause permanent
damage to the device. Additionally, device operation at the absolute maximum
ratings for extended periods of time may have adverse effects on the device.

Maximum Allowed Overshoot/Undershoot Voltage
During transitions, input signals may overshoot to the voltage shown in Table 1–3
and undershoot to -2.0 V for input currents less than 100 mA and periods shorter than
20 ns.
Table 1–3 lists the maximum allowed input overshoot voltage and the duration of the
overshoot voltage as a percentage of device lifetime. The maximum allowed
overshoot duration is specified as a percentage of high-time over the lifetime of the
device. A DC signal is equivalent to 100% duty cycle. For example, a signal that
overshoots to 4.3 V can only be at 4.3 V for ~5% over the lifetime of the device; for a
device lifetime of 10 years, this amounts to 5/10ths of a year.

DC Characteristics
This section lists the supply current, I/O pin leakage current, input pin capacitance,
on-chip termination tolerance, and hot socketing specifications.
Supply Current
Standby current is the current the device draws after the device is configured, with no
inputs or outputs toggling and no activity in the device. Since these currents vary
largely with resources used, use the Excel-based Early Power Estimator (EPE) to get
supply current estimates for your design.

Notes to Table 1–18:
(1)

(3)
(4)
(5)
VIO (vertical I/O) is top and bottom I/Os; HIO (horizontal I/O) is left and right I/Os.
1.4V/1.5V PCML transceiver I/O standard specifications are described in the section “Transceiver Performance Specifications” on page 1–10.
RL range: 90 <= RL <= 110 Ω.
LVPECL specifications apply only to CLK input pins on column I/Os.
For DMAX > 700 Mbps, the minimum input voltage is 0.85 V; the maximum input voltage is 1.75 V. For FMA X <=700Mbps, the minimum input voltage
is 0.45 V; the maximum input voltage is 1.95 V.
Power Consumption
Altera® offers two ways to estimate power consumption for a design: the Excel-based
Early Power Estimator and the Quartus® II PowerPlay Power Analyzer feature.
The interactive Excel-based Early Power Estimator is typically used prior to designing
the FPGA in order to get a magnitude estimate of the device power. The Quartus II
PowerPlay Power Analyzer provides better quality estimates based on the specifics of
the design after place-and-route is complete. The PowerPlay Power Analyzer can
apply a combination of user-entered, simulation-derived, and estimated signal
activities that, combined with detailed circuit models, can yield very accurate power
estimates.
f
For more information about power estimation tools, refer to the PowerPlay Early Power
Estimator User Guide for Stratix III and Stratix IV FPGAs and the PowerPlay Power
Analysis chapter in the Quartus II Handbook.
Switching Characteristics
This section provides performance characteristics of Stratix IV core and periphery
blocks for commercial grade devices.
These characteristics can be designated as Preliminary and Final. Preliminary
characteristics are created using simulation results, process data, and other known
parameters. Final numbers are based on actual silicon characterization and testing.
These numbers reflect the actual performance of the device under worst-case silicon
process, voltage, and junction temperature conditions. The upper-right hand corner of
a table shows the designation as “Preliminary” or “Final”.
Transceiver Performance Specifications
This sections describes transceiver performance specifications.

Notes to Table 1–19:
(1) The -2x speed grade is the fastest speed grade offered in the following Stratix IV GX devices: EP4SGX70DF29, EP4SGX110DF29,
EP4SGX110FF35, EP4SGX230DF29, EP4SGX110FF35, EP4SGX230DF29, EP4SGX230FF35, EP4SGX290FF35, EP4SGX290FH29,
EP4SGX360FF35, and EPSGX360FH29.
(2) The minimum reconfig_clk frequency is 2.5 MHz if the transceiver channel is configured in transmitter only mode. The minimum
reconfig_clk frequency is 37.5MHz if the transceiver channel is configured in receiver only or receiver and transmitter mode. For more
details, refer to the Stratix IV Dynamic Reconfiguration chapter in volume 1 of the Stratix IV Device Handbook.
(3) The device cannot tolerate prolonged operation at this absolute maximum.
(4) The 1.1-V RX VIC M setting must be used if the input serial data standard is LVDS and the link is DC coupled.
(5) The rate matcher supports only up to +/-300 ppm.
(6) Time taken to rx_pll_locked goes high from rx_analogreset deassertion. Refer to Figure 1–1.
(7) Time for which the CDR must be kept in lock-to-reference mode after rx_pll_locked goes high and before rx_locktodata is asserted
in manual mode. Refer to Figure 1–1.
(8) Time taken to recover valid data after the rx_locktodata signal is asserted in manual mode. Refer to Figure 1–1.
(9) Time taken to recover valid data after the rx_freqlocked signal goes high in automatic mode. Refer to Figure 1–2.
Figure 1–1 shows the lock time parameters in manual mode. Figure 1–2 shows the
lock time parameters in automatic mode.

Notes to Table 1–32:
(1) When J = 4 to 10, the SERDES block is used.
(2) When J = 1 or 2, the SERDES block is bypassed.
(3) The input clock frequency and the W factor must satisfy the following Left/Right PLL output specification:
150 <= input clock frequency × W <= 1600 MHz.
(4) Specifications for -3 and -4 speed grades will be available after silicon characterization.
(5) Pending silicon characterization.
(6) The minimum specification is dependent on the clock source (for example, PLL or clock pin) and the clock routing resource (global, regional,
or local) utilized. The I/O differential buffer and input register does not have a minimum toggle rate.
(7) Same as device clock tree F M AX.

Notes to Table 1–34:
(1) Numbers are preliminary pending characterization. The supported operating frequencies listed here are memory interface maximums for the FPGA device family.
Your design’s actual achievable performance is based on design and system-specific factors, as well as static timing analysis of the completed design.
(2) Column I/Os refer to top and bottom I/Os. Row I/Os refer to left and right I/Os.
(3) The row I/O banks do not support 1.5-V HSTL and SSTL Class II I/O standards.
(4) This applies for interfaces with both modules and components.
(5) The QDRII+ SRAM devices with 2.0 clock cycle latency are not supported due to hardware limitations.
(6) Stratix IV devices in the 780- and 1152-pin packages support ×36 QDRII+/QDRII SRAM at a lower maximum frequency as detailed in the External Memory
Interfaces in Stratix IV Devices chapter in volume 1 of the Stratix IV Device Handbook.

Notes to Table 1–36:
(1) Numbers, based on using the half-rate controller, are preliminary until characterization is final. The supported operating frequencies listed here
are memory interface maximums for the FPGA device family. Your design’s actual achievable performance is based on design and
system-specific factors as well as static timing analysis of the completed design.
(2) The performance listed in this table is lower than the performance listed in Table 1–34 due to double loading of the CQ/CQn pins. Double loading
causes degradation in the signal slew rate which affects FPGA delay. Furthermore, due to the difference in slew rate, there is a shift in the setup
and hold time window. You can perform an IBIS simulation to illustrate the shift in the clock signals.
(3) Column I/Os refer to top and bottom I/Os. Row I/Os refer to left and right I/Os.
(4) The QDRII+ SRAM devices with 2.0 clock cycle latency are not supported due to hardware limitations.

4 to 6.
(2) The typical value equals the average of the minimum and maximum values.
(3) The delay settings are linear, with a cumulative delay variation of 40 ps for all speed grades. For example, when
using a -2 speed grade and applying a 10 phase offset settings to a 90° phase shift at 400 MHz, the expected
average cumulative delay is [625 ps + (10 * 10.5 ps) ± 20 ps] = 730 ps ± 20 ps

general purpose I/O pins.
(2) Detailed DCD specifications pending silicon characterization.
I/O Timing
Altera offers two ways to determine I/O timing: the Excel-based I/O timing and the
Quartus II Timing Analyzer.
The Excel-based I/O timing provides pin timing performance for each device density
and speed grade. The data is typically used prior to designing the FPGA to get an
estimate of the timing budget as part of the link timing analysis. The Quartus II
Timing Analyzer provides a more accurate and precise I/O timing data based on the
specifics of the design after place-and-route is complete.

The Excel-based I/O timing spreadsheet can be downloaded from the Stratix IV
Device Literature webpage.

voltage
referenced I/O
standard
The JEDEC standard for SSTl and HSTL I/O defines both the AC and DC input signal values.
The AC values indicate the voltage levels at which the receiver must meet its timing
specifications. The DC values indicate the voltage levels at which the final logic state of the
receiver is unambiguously defined. Once the receiver input has crossed the AC value, the
receiver changes to the new logic state.
The new logic state is then maintained as long as the input stays beyond the AC threshold.
This approach is intended to provide predictable receiver timing in the presence of input
waveform ringing as shown in the following figure:
