GENERAL DESCRIPTION
The ADN4600 is an asynchronous, nonblocking crosspoint
switch with eight differential PECL-/CML-compatible inputs
with programmable equalization and eight differential CML
outputs with programmable output levels and pre-emphasis or
de-emphasis. The operation of this device is optimized for NRZ
data at rates up to 4.25 Gbps.
The receive inputs provide programmable equalization with
nine settings to compensate for up to 30 in. of FR4 and
programmable pre-emphasis with seven settings to compensate
for up to 30 in. of FR4 at 4.25 Gbps.
The ADN4600 nonblocking switch core implements an 8 脳 8
crossbar and supports independent channel switching through the
I
2
C control interface. Every channel implements an asynchronous
path supporting NRZ data rates from dc to 4.25 Gbps. Each
channel is fully independent of other channels. The ADN4600
has low latency and very low channel-to-channel skew.
The main application for the ADN4600 is to support switching
on the backplane, line card, or cable interface sides of serial links.
The ADN4600 is packaged in a 9 mm 脳 9 mm, 64-lead LFCSP
package and operates from 鈭?0擄C to +85擄C.
