DESCRIPTION:
The IDT5V9885T is a programmable clock generator intended for high
performance data-communications, telecommunications, consumer, and
networking applications. There are three internal PLLs, each individually
programmable, allowing for three unique non-integer-related frequencies.
The frequencies are generated from a single reference clock. The
reference clock can come from one of the two redundant clock inputs. A
glitchless automatic or manual switchover function allows any one of the
redundant clocks to be selected during normal operation.
The IDT5V9885T can be programmed through the use of the I2C or
JTAG interfaces. The programming interface enables the device to be
programmed when it is in normal operation or what is commonly known as
in-system programmable. An internal EEPROM allows the user to save
and restore the configuration of the device without having to reprogram it
on power-up. JTAG boundary scan is also implemented.
Each of the three PLLs has an 8-bit pre-scaler and a 12-bit feedback
divider. This allows the user to generate three unique non-integer-related
frequencies. The PLL loop bandwidth is programmable to allow the user
to tailor the PLL response to the application. For instance, the user can tune
the PLL parameters to minimize jitter generation or to maximize jitter
attenuation. Spread spectrum generation and fractional divides are
allowed on two of the PLLs.
There are 10-bit post dividers on five of the six output banks. Two of the
six output banks are configurable to be LVTTL, LVPECL, or LVDS. The
other four output banks are LVTTL. The outputs are connected to the PLLs
via the switch matrix. The switch matrix allows the user to route the PLL
outputs to any output bank. This feature can be used to simplify and optimize
the board layout. In addition, each output's slew rate and enable/disable
function can be programmed.
