DS91M040  
125 MHz Quad M-LVDS Transceiver  
General Description  
Features  
The DS91M040 is a quad M-LVDS transceiver designed for  
driving / receiving clock or data signals to / from up to four  
multipoint networks.  
DC - 125 MHz / 250 Mbps low jitter, low skew, low power  
operation  
Wide Input Common Mode Voltage Range allows up to  
±1V of GND noise  
M-LVDS (Multipoint LVDS) is a new family of bus interface  
devices based on LVDS technology specifically designed for  
multipoint and multidrop cable and backplane applications. It  
differs from standard LVDS in providing increased drive cur-  
rent to handle double terminations that are required in multi-  
point applications. Controlled transition times minimize re-  
flections that are common in multipoint configurations due to  
unterminated stubs. M-LVDS devices also have a very large  
input common mode voltage range for additional noise margin  
in heavily loaded and noisy backplane environments.  
Conforms to TIA/EIA-899 M-LVDS Standard  
Pin selectable M-LVDS receiver type (1 or 2)  
Controlled transition times (2.0 ns typ) minimize reflections  
8 kV ESD on M-LVDS I/O pins protects adjoining  
components  
Flow-through pinout simplifies PCB layout  
Small 5 mm x 5 mm LLP-32 space saving package  
A single DS91M040 channel is a half-duplex transceiver that  
accepts LVTTL/LVCMOS signals at the driver inputs and con-  
verts them to differential M-LVDS signal levels. The receiver  
inputs accept low voltage differential signals (LVDS, BLVDS,  
M-LVDS, LVPECL and CML) and convert them to  
3V LVCMOS signals. The DS91M040 supports both M-LVDS  
type 1 and type 2 receiver inputs.  
Applications  
Multidrop / Multipoint clock and data distribution  
High-Speed, Low Power, Short-Reach alternative to  
TIA/EIA-485/422  
Clock distribution in AdvancedTCA (ATCA) and  
MicroTCA (μTCA, uTCA) backplanes

M-LVDS Receiver Types  
The EIA/TIA-899 M-LVDS standard specifies two different  
types of receiver input stages. A type 1 receiver has a con-  
ventional threshold that is centered at the midpoint of the input  
amplitude, VID/2. A type 2 receiver has a built in offset that is  
100mV greater then VID/2. The type 2 receiver offset acts as  
a failsafe circuit where open or short circuits at the input will  
always result in the output stage being driven to a low logic  
state.

Note 10: The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified  
or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed.  
Note 11: Typical values represent most likely parametric norms for VDD = +3.3V and TA = +25°C, and at the Recommended Operation Conditions at the time of  
product characterization and are not guaranteed.  
Note 12: Specification is guaranteed by characterization and is not tested in production.  
Note 13: tSKD1, |tPLHD − tPHLD|, Pulse Skew, is the magnitude difference in differential propagation delay time between the positive going edge and the negative  
going edge of the same channel.  
Note 14: tSKD2, Channel-to-Channel Skew, is the difference in propagation delay (tPLHD or tPHLD) among all output channels.  
Note 15: tSKD3, Part-to-Part Skew, is defined as the difference between the minimum and maximum differential propagation delays. This specification applies to  
devices at the same VDD and within 5°C of each other within the operating temperature range.  
Note 16: tSKD4, Part-to-Part Skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over  
recommended operating temperature and voltage ranges, and across process distribution. tSKD4 is defined as |Max − Min| differential propagation delay.  
Note 17: CL includes fixture capacitance and CD includes probe capacitance.  
Note 18: Measured on a clock edge with a histogram and an acummulation of 1500 histogram hits. Input stimulus jitter is subracted geometrically.
