Description
This PLL clock buffer is designed for 2.5-V
DD
and 2.5-AV
DD
operation and differential output levels.
This device is a zero delay buffer that distributes a clock input
CLKIN to six differential pairs of clock outputs (CLKT[0:5],
CLKC[0:5]) and one feedback clock output FBOUT. The clock
outputs are controlled by the input clock CLKIN and the
feedback clock FBIN.
The two-line serial bus can set each output clock pair
(CLKT[0:5], CLKC[0:5]) to the Hi-Z state. When AV
DD
is
grounded, the PLL is turned off and bypassed for test
purposes.
The PLL in this device uses the input clock CLKIN and the
feedback clock FBIN to provide high-performance, low-skew,
low–jitter output differential clocks.
