Hardware and Software PLL Lock detection
The
ICS1524
is a low-cost, very high-performance
frequency generator and phase controlled clock synthe-
sizer. It is perfectly suited to phase controlled clock
synthesis and distribution as well as line-locked and
genlocked applications.
The
ICS1524
offers two channels of clock phase con-
trolled outputs; CLK and DPACLK. These two output
channels have both 250 MHz PECL differential and 150
MHz SSTL_3 single-ended output pins. The CLK output
channel has a fixed phase relationship to the PLL’s input
and the DPACLK uses the Dynamic Phase Adjust cir-
cuitry to allow control of the clock phase relative to input
signal.
Optionally, the CLK outputs can operate at half the clock
rate and phase aligned with the DPACLK channel, en-
abling deMUXing of multiplexed analog-to-digital
converters. The FUNC pin provides either the regener-
ated input from the phase-locked loop (PLL) divider
chain output or a re-synchronized and sharpened input
HSYNC.
The advanced PLL uses either its internal program-
mable feedback divider or an external divider and is
programmed by a standard I

C-bus serial interface.
