onsemi NB3N3020DTG

The onsemi NB3N3020DTG is a versatile clock multiplier designed for applications requiring precise frequency synthesis. It integrates a Phase-Locked Loop (PLL) to multiply an input reference from LVCMOS, LVTTL, or a crystal, into a clean, low-jitter output up to 210 MHz. With a single circuit, it provides flexible output options including LVCMOS, LVPECL, and LVTTL, making it suitable for a wide range of timing applications in networking, telecom, and industrial systems. Its compact 16-TSSOP package and wide temperature range ensure reliable performance in space-constrained and demanding environments.

• Flexible I/O Options: Supports LVCMOS, LVTTL, and Crystal inputs with LVCMOS, LVPECL, and LVTTL outputs, simplifying system integration.
• Low Jitter PLL: Integrated PLL ensures clean clock multiplication, critical for high-speed digital communication.
• Wide Temperature Range: -40°C to 85°C operation guarantees reliability in industrial and automotive environments.
• High Frequency Capability: Up to 210 MHz output supports a broad range of processor and logic requirements.

Telecom Clock Multiplication

Generate clean, multiplied clocks for telecom line cards and switches. The PLL ensures low jitter, critical for maintaining signal integrity in high-speed serial links.

Networking Equipment Timing

Provide precise timing for Ethernet switches and routers. The LVCMOS/LVTTL outputs interface directly with MAC/PHY chips, while the crystal input simplifies reference design.

Processor Clock Generation

Create the core clock for microprocessors, DSPs, or FPGAs. The 210 MHz maximum frequency covers many embedded processor requirements, and the LVPECL output option supports high-speed differential signaling.

Audio/Video Synchronization

Generate synchronized clocks for audio codecs and video converters. The low-jitter PLL output helps maintain stable sample rates, reducing artifacts and drift.

Industrial Control Timing

Provide reliable clock signals for PLCs and industrial automation. The wide -40°C to 85°C temperature range ensures operation in harsh environments.

Test and Measurement Equipment

Use as a frequency multiplier in signal generators and counters. The multiple output types (LVCMOS, LVPECL, LVTTL) allow easy connection to various test modules.
