Description

PI90LV387/ PI90LVB387 consists of sixteen differential line

driv ers that im ple ment the elec tri cal characteristics of low-volt-

age dif fer en tial sig nal ing (LVDS). This signaling technique lowers

output volt age levels to reduce power, increase switching speeds,

and allow op er a tion with a 3V supply rail.

The intended application of this device and signaling technique

is for point-to-point baseband (single termination) and multi-

point (double termination) data trans mis sion over a controlled

im ped ance me dia of ap prox i mate ly 100Ω and 50Ω (LVB387).

The trans mis sion media may be printed-circuit board traces, back-

planes, or cables. The large num ber of drivers integrated into the

same substrate, with the low pulse skew of balanced sig nal ing,

allows extremely precise timing align ment of clock and data for

syn chro nous parallel data transfers. When used with its companion

16-chan nel receivers, the PI90LV386 or PI90LVT386, over 400

million data trans fers per second in single-edge clocked systems

are pos si ble with very little power.

(Note: The ultimate rate and distance of data transfer is de pen dent

upon attenuation char ac ter is tics of the media, the noise coupling

to the environment, and other system char ac ter is tics.)

The drivers are enabled in groups of ﬁ ve. When disabled, driver

outputs are at a high impedance. Each driver input (D

able (EN) have an internal pulldown that drives the input to a low

level when open circuited.

The parts are characterized for operation from –40°C to 85°C.
