EXTERNAL INPUT CLOCKS
The external input clock to the ML6510 can be either a
differential Pseudo-ECL clock or a single-ended TTL clock.
This is selected using the CS bit in the serial shift register.
For the single-ended TTL clock tie the CLK
INH
and CLK
INL
pins together. The ML6510 ensures that there is a well-
defined phase difference between the input and output
clocks.
RESET
AND LOCK
When
RESET
is de-asserted, the internal programming
logic will become active, loading in the configuration bits
(see Programming the ML6510). Once the configuration is
loaded, the PLL will lock onto the reference signal, and
then the deskew blocks will adapt to the load conditions.
When all eight output clocks are stable and deskewed,
LOCK will be asserted. The asserted polarity of lock is
high. Thus, LOCK can be used to indicate that the system
is ready, or it can be used to drive the
RESET
input of
another PACMan in a clock tree.

RESET
may be reasserted at any time to reset the chip
operations. Following a
RESET
assertion of valid pulse
width (see Programming Electrical Characteristics), the
ML6510 must again be loaded with a configuration, then
it will re-lock and reassert lock when all eight clock
outputs are stable and deskewed.
