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 I2C-bus™ serial interface.
