2.2. Intel® MAX® 10 LVDS SERDES I/O Standards Support

The Intel® MAX® 10 D and S device variants support different LVDS I/O standards. All I/O banks in Intel® MAX® 10 devices support true LVDS input buffers and emulated LVDS output buffers. However, only the bottom I/O banks support true LVDS output buffers.
Note: The 1.8 V LVDS buffers are supported as inputs on all high-speed I/O banks but as outputs only on the bottom banks. The low-speed and high-speed DDR3 I/O banks do not support 1.8 V LVDS. The 1.8 V LVDS I/O standard is supported in industrial- and commercial-grade Intel® MAX® 10 dual supply devices except in packages V36 and V81. Refer to the related information.

Dual Supply Device

Single Supply Device

LVDS All Bottom banks only Yes Yes Yes
  • All I/O banks support 2.5 V true LVDS input buffers.
  • Only the bottom I/O banks support 2.5 V true LVDS output buffers.
1.8 V LVDS 4 Non-DDR3 high-speed I/O banks Bottom banks only Yes Yes, except package V36 and V81
  • All non-DDR3 high-speed I/O banks support 1.8 V true LVDS input buffers.
  • Only the bottom I/O banks support 1.8 V true LVDS output buffers.
Emulated LVDS (three resistors) All Yes Yes Yes

All I/O banks support emulated LVDS output buffers.

True RSDS Bottom Yes Yes Yes
Emulated RSDS (single resistor) All Yes Yes

All I/O banks support emulated RSDS output buffers.

Emulated RSDS (three resistors) All Yes Yes Yes

All I/O banks support emulated RSDS output buffers.

True Mini-LVDS Bottom Yes Yes
Emulated Mini-LVDS (three resistors) All Yes Yes

All I/O banks support emulated Mini-LVDS output buffers.

PPDS Bottom Yes Yes
Emulated PPDS (three resistors) All Yes Yes
Bus LVDS All Yes Yes Yes Yes
  • Bus LVDS (BLVDS) output uses two single-ended outputs with the second output programmed as inverted.
  • BLVDS input uses LVDS input buffer.
  • You can tristate BLVDS output.
LVPECL All Yes Yes Yes

Supported only on dual function clock input pins.

TMDS All Yes Yes
  • Requires external termination but does not require VREF.
  • Requires external level shifter to support 3.3 V TMDS input. This level shifter must convert the TMDS signal from AC-coupled to DC-coupled before you connect it to the Intel® MAX® 10 input buffer.
  • TMDS receiver support uses dedicated 2.5 V LVDS input buffer.
Sub-LVDS All Yes Yes Yes
  • Transmitter supports only emulated Sub-LVDS using emulated 1.8 V differential signal as output.
  • Requires external output termination.
  • Does not require VREF.
  • Sub-LVDS receiver support uses dedicated 2.5 V LVDS input buffer.
SLVS All Yes Yes Yes
  • SLVS transmitter support uses emulated LVDS output.
  • Requires external termination but does not require VREF.
  • SLVS receiver support uses dedicated 2.5 V LVDS input buffer.
HiSpi All Yes Yes
  • Only input is supported because HiSpi is a unidirectional I/O standard.
  • Requires external termination but does not require VREF.
  • HiSpi receiver support uses dedicated 2.5 V LVDS input buffer.
4 The 1.8 V LVDS buffers are supported as inputs on all high-speed I/O banks but as outputs only on the bottom banks. The low-speed and high-speed DDR3 I/O banks do not support 1.8 V LVDS. The 1.8 V LVDS I/O standard is supported in industrial- and commercial-grade Intel® MAX® 10 dual supply devices except in packages V36 and V81.
