DESCRIPTION:
The IDT5T929 generates a high precision FEC (Forward Error Cor-
rection) or non-FEC source clock for SONET/SDH systems as well as a
source clock for Gigabit Ethernet systems. This device also has clock
regeneration capability: it creates a "clean" version of the clock input by
using the internal oscillator to square the input clock's rising and falling
edges and remove jitter. In the event that the main clock input fails, the
device automatically locks to a backup reference clock using a hitless
switchover mechanism
This device detects loss of valid CLKIN and leaves the VCO of the PLL at
the last valid frequency while an alternate input REFIN is selected. If CLKIN
and REFIN are different frequencies, the multiplication factor will be adjusted to
retain the same output frequency.
The IDT5T929 can act as a translator froma differential LVPECL, LVDS, or
single-ended LVTTL input to LVPECL or LVDS outputs. The IDT5T929-10
has LVDS outputs and the IDT5T929-30 has LVPECL outputs.
The two modes of output frequency range are controlled by the SELmode.
When SELmode is high or low, the Q
OUT
is a multiplied version of the input clock
while Q
REG
is a regenerated version of the input clock.
