TI Introduces Multipoint-LVDS Single-Channel Receivers

M-LVDS Devices Save Board Space, Power and Cost in Backplane Applications

Jan 31, 2007

DALLAS (Jan. 31, 2007) -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry's first dedicated multipoint-LVDS (M-LVDS) receivers. To date, customers converting M-LVDS to LVTLL for multi-drop clock distribution have used transceivers with unnecessary integrated driver circuitry. The new single-channel receivers save space, power consumption and cost in end equipment such as cellular base stations, central office switches, network switches, routers and AdvancedTCA® systems. The devices provide better technical performance in applications such as clock and synchronization distribution and control, as well as data signal transfer over backplanes and cables.  For more information see www.ti.com/sc07017.

The SN65MLVD2 type-1 M-LVDS receiver provides the best noise margin with switching occurring near the zero volt (differential) input level. The SN65MLVD3 type-2 M-LVDS receiver provides built-in failsafe protection and eliminates the need for external pull-up/down resistors. Other key features include:

  • Clock frequencies up to 125 MHz 
  • Signaling rates up to 250 Mbps 
  • Supports 30-ohms to 55-ohms line impedances 
  • SN65MLVD2 type-1 receive with 25 mV of input threshold hysteresis to prevent output ringing 
  • SN65MLVD3 type-2 receive with 100 mV offset threshold to detect open-circuit and idle-bus conditions 
  • Wide receiver common-mode Vin range, –1 V to 3.4 V allowing up to 2 V of ground noise 
  • Meets or exceeds the M-LVDS standard TIA/EIA-899 for multipoint topology 
  • High input impedance with low Vcc 
  • Bus-pin HBM ESD protection exceeds 9 kV

The addition of the




complements Texas Instruments' M-LVDS family of products including transceivers, drivers, receivers and clock fan-out buffers. Texas Instruments' interface IC offering for telecommunications also includes LVDS, PECL, RS-485, PCI-Express and gigabit Ethernet serializers and deserializers (SerDes).
