What are the key features of LMK03001ISQ/NOPB?
- Output clock frequency up to 2160 MHz enabling direct clocking of high-speed ADCs, DACs, FPGAs, and SerDes interfaces without external multipliers
- 800 MHz nominal primary clock input with on-chip PLL clock conditioning for ultra-low jitter performance in demanding communications designs
- Compact 48-pin QFN (XQCC) chip-carrier package with very thin profile enabling high-density PCB integration in space-constrained line cards
- RoHS-compliant lead-free e3 finish with 260°C peak reflow temperature compatibility for standard automated SMT assembly processes
What is LMK03001ISQ/NOPB used for?
The LMK03001ISQ/NOPB is used in high-speed communications line cards, wireless base station clock trees, and test-and-measurement equipment where precise, low-jitter clock signals up to 2160 MHz are required for ADC and DAC synchronization. Its clock conditioning capability cleans up reference oscillator phase noise before distributing clocks to multiple high-speed converter channels, improving system dynamic range. FPGA and DSP designs that require deterministic multi-GHz clocking for DDR memory controllers and SerDes transceivers also benefit from the LMK03001's conditioned output.

Frequently Asked Questions
What is the maximum output clock frequency of the LMK03001ISQ/NOPB, and what types of high-speed ICs can it directly clock?
The LMK03001ISQ/NOPB supports output clock frequencies up to 2160 MHz. This range covers direct clocking of GHz-rate ADCs and DACs used in wireless infrastructure, as well as FPGA transceiver reference clocks and DDR4 memory controllers. At 2160 MHz, the device eliminates the need for an additional frequency multiplier stage, simplifying the clock distribution architecture and reducing phase noise contributions from additional PLL stages.
How does the LMK03001ISQ/NOPB improve clock quality compared to feeding a raw crystal oscillator directly to a high-speed ADC?
A raw crystal oscillator typically has higher phase noise at offset frequencies of 1 kHz to 1 MHz that degrades ADC effective number of bits (ENOB). The LMK03001ISQ/NOPB conditions the 800 MHz primary clock input through its internal PLL, attenuating oscillator phase noise and reference spurs before generating the output clock. This jitter cleaning can improve ADC SNR by several dB, which is critical for 14-bit or 16-bit converters sampling at hundreds of MHz where clock jitter is the dominant noise source.
What package does the LMK03001ISQ/NOPB use, and how does that affect PCB layout for a 2 GHz clock distribution design?
The LMK03001ISQ/NOPB is housed in a 48-pin QFN (XQCC) chip carrier with a very thin profile and exposed thermal pad. At output frequencies up to 2160 MHz, PCB layout is critical: the QFN package's short lead stubs minimize parasitic inductance, and the exposed pad must be soldered to a ground plane flood for both thermal management and RF signal return path integrity. Trace lengths from output pins to receiver inputs should be matched to within 100 µm to minimize clock skew between channels.
For a wireless base station design using multiple high-speed ADCs, how does the LMK03001ISQ/NOPB simplify the clock tree compared to discrete solutions?
In a typical base station receiver, multiple 14-bit or 16-bit ADCs sampling at 500 MHz to 1 GHz require synchronous, low-jitter clock inputs. The LMK03001ISQ/NOPB conditions a single 800 MHz reference and distributes up to 2160 MHz clocks to multiple ADC channels from one 48-pin IC. This replaces a multi-component discrete clock tree involving separate buffers, dividers, and PLL chips, reducing BOM count, board area, and the number of independent PCB layout critical paths that must be optimized for phase noise.
