This device provides two factory-programmed default power-up
configurations burned into One-Time Programmable (OTP) memory.
The configuration to be used is selected by the CONFIG pin. The two
configurations are specified by the customer and are programmed by
IDT during the final test phase from an on-hand stock of blank
devices. The two configurations may be completely independent of
one another.
One usage example might be to install the device on a line card with
two optional daughter cards: an OC-12 option requiring a 622.08MHz
LVDS clock translated from a 19.44MHz input and a Gigabit Ethernet
option requiring a 125MHz LVPECL clock translated from the same
19.44MHz input reference.
To implement other configurations, these power-up default settings
can be overwritten after power-up using the I
2
C interface and the
device can be completely reconfigured. However, these settings
would have to be re-written next time the device powers-up.
The Preliminary Information presented herein represents a product in pre-production. The noted characteristics are based on initial product characterization and/or qualification.
