FULLY INTEGRATED,
FREQUENCY FLEXIBLE GENLOCK SOLUTION
DESCRIPTION
Silicon Laboratories’ Si5324 Any-Rate Precision Clock is the industry’s lowest jitter, most
highly integrated video clock IC optimized for genlock applications. Based on Silicon Labs’
patented DSPLL® technology, the Si5324 has a fully integrated, digitally programmable
loop filter that supports loop bandwidths ranging from 4 Hz to 525 Hz as well as a low
phase noise internal VCO. By consuming less than 10% of the overall 3G-SDI jitter budget
required in next generation video applications, the Si5324 simplifies design and eases
system-level SDI jitter testing. In addition, the Si5324 provides any-rate frequency
flexibility by generating virtually any output frequency from 2 kHz to 1.4 GHz from any
input frequency ranging from 2 kHz to 710 MHz enabling a single IC design for multi-rate
video applications.

High Performance
The Si5324 is the industry’s lowest jitter
genlock clock IC. The device provides any-
rate frequency synthesis simplifying HD
video and audio clock generation. With
jitter performance of 5 ps pk-pk, the Si5324
delivers significant jitter margin in 3G-SDI
serializer applications, reducing design risk
and improved link performance.
Highly Integrated
The Si5324 offers the industry’s most
highly integrated video clock generator IC
requiring no external PLL components (low
pass filter, charge pump, or VCXO). Because
all PLL components are integrated, board-
level noise immunity is improved reducing
design risk versus traditional video clock IC
solutions.
Any-Rate Frequency Flexibility
The Si5324’s any rate frequency flexibility
enables a single device to generate all
common genlock reference frequencies
required in next-generation SD/HD video
and audio equipment. The Si5324 is easily
reconfigurable via I2C/SPI interface and
requiresnocomponentchangesfordifferent
frequency plans, simplifying design reuse.
