DS90CP22

2X2 800 Mbps LVDS Crosspoint Switch

General Description

Features

n Low jitter 800 Mbps fully differential data path

n 75 ps (typ) of pk-pk jitter with PRBS = 2²³−1 data

pattern at 800 Mbps

DS90CP22 is a 2x2 crosspoint switch utilizing LVDS (Low

Voltage Differential Signaling) technology for low power, high

speed operation. Data paths are fully differential from input

to output for low noise generation and low pulse width dis-

tortion. The non-blocking design allows connection of any

input to any output or outputs. LVDS I/O enable high speed

data transmission for point-to-point interconnects. This de-

vice can be used as a high speed differential crosspoint, 2:1

mux, 1:2 demux, repeater or 1:2 signal splitter. The mux and

demux functions are useful for switching between primary

and backup circuits in fault tolerant systems. The 1:2 signal

splitter and 2:1 mux functions are useful for distribution of

serial bus across several rack-mounted backplanes.

n Single +3.3 V Supply

n Less than 330 mW (typ) total power dissipation

n Non-blocking "’Switch Architecture"’

n Balanced output impedance

n Output channel-to-channel skew is 35 ps (typ)

n Configurable as 2:1 mux, 1:2 demux, repeater or 1:2

signal splitter

n LVDS receiver inputs accept LVPECL signals

n Fast switch time of 1.2ns (typ)

n Fast propagation delay of 1.3ns (typ)

The DS90CP22 accepts LVDS signal levels, LVPECL levels

directly or PECL with attenuation networks.

n Receiver input threshold

100 mV

n Available in 16 lead TSSOP and SOIC packages

n Inter-operates with ANSI/TIA/EIA-644-1995 LVDS

standard

The individual LVDS outputs can be put into TRI-STATE by

use of the enable pins.

For more details, please refer to the Application Information

section of this datasheet.

n Operating Temperature: −40˚C to +85˚C
