DESCRIPTION
The LTC
receiver that can operate at data rates as high as 50Mbps.
A unique architecture provides very stable propagation
delays and low skew over a wide input common mode,
input overdrive and ambient temperature range. Propaga-
tion delay is 18ns 3ns, while typically t
500ps and channel-to-channel skew is 400ps.
Each receiver translates differential input levels (V
100mV) into valid CMOS and TTL output levels. Its high
input resistance ( 18k) allows many receivers to be con-
nected to the same driver. The receiver outputs go into a
high impedance state when disabled.
Protection features include thermal shutdown and a con-
trolled maximum short-circuit current (50mA max) that
does not oscillate in and out of short-circuit mode. Input
resistance remains 18k when the device is unpowered or
disabled, thus allowing the LTC1520 to be hot swapped into
a backplane without loading the data lines.
The LTC1520 operates from a single 5V supply and draws
12mA of supply current. The part is available in a 16-lead
narrow SO package.
