Product details
Overview
LMK60I2-100M00SIAT from Texas Instruments is a factory-programmed, low-jitter HCSL oscillator delivering 100 MHz output with ±50 ppm total frequency tolerance, 150 fs RMS phase jitter (12 kHz–20 MHz), and robust –60 dBc PSRR across 50 kHz–1 MHz supply ripple. It operates from a single 3.3-V supply over –40°C to +85°C and serves as a high-stability clock source for FPGA and processor reference timing in telecom infrastructure.
For engineers reviewing the LMK60I2-100M00SIAT datasheet, LMK60I2-100M00SIAT pinout, LMK60I2-100M00SIAT application, or LMK60I2-100M00SIAT equivalent, this page provides verified package mapping, differential output behavior, thermal derating guidance, and validated alternatives for HCSL clocking in high-speed digital systems.
Technical Context
The LMK60I2-100M00SIAT integrates a high-performance PLL-based oscillator core with internal power conditioning to suppress supply noise, enabling stable 100 MHz HCSL output without external crystal or loop filter components. Its architecture supports fast startup (10 ms) and OE-controlled output disable with 50 µs enable/disable latency.
It uses a fixed-output configuration-no I²C or SPI interface-and relies on factory programming for frequency and format. The device implements differential HCSL signaling with VOH = 660–900 mV, VOL = –100–100 mV, and VCROSS = 250–475 mV, optimized for direct connection to 50-Ω terminated FPGA clock inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 100 MHz - precisely factory-set; no user tuning required. |
| Jitter (RMS) | 150 fs (12 kHz–20 MHz) - meets stringent SerDes and PCIe Gen4/5 reference clock requirements. |
| Output Format | HCSL - compatible with standard 50-Ω FPGA clock receivers; no external termination needed. |
| Frequency Tolerance | ±50 ppm - includes initial calibration, temperature drift (–40°C to +85°C), voltage variation, solder reflow, and 5-year aging. |
| Supply Voltage | 3.3 V ±5% - single-rail operation; supports common system rail without LDO overhead. |
| PSRR | –60 dBc at 50 kHz–1 MHz - rejects board-level switching noise without additional filtering. |
| Startup Time | 10 ms - time from VDD ≥3.135 V to valid output; enables synchronization with power sequencing. |
Pinout & Package
LMK60I2-100M00SIAT is housed in a 7.0 mm × 5.0 mm × 1.15 mm QFM (SIA) 6-pin package, pin-compatible with industry-standard 7050 XO footprints. The package features an exposed thermal pad connected to GND for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Digital control input | LVCMOS-enable with internal pull-up; drives output pair to high-Z when low. |
| 2 (NC) | No-connect | Unbonded die pad; must remain floating per TI design rules. |
| 3 (GND) | Ground reference | Primary analog/digital ground return; requires ≥3 thermal vias to inner ground plane. |
| 4 (OUTN) | Differential output (complement) | HCSL negative leg; paired with OUTP for 100 MHz differential clock signal. |
| 5 (OUTP) | Differential output (true) | HCSL positive leg; delivers 100 MHz clock with 45–55% duty cycle and <350 ps rise/fall time. |
| 6 (VDD) | Power supply | 3.3-V analog supply; requires local 10 µF / 1 µF / 0.1 µF decoupling network. |
Key Features
| Feature | Design Value |
|---|---|
| Low-jitter HCSL output | 150 fs RMS jitter enables reliable sampling in 10+ Gbps serial links without added jitter cleanup. |
| Integrated power conditioning | –60 dBc PSRR eliminates need for ultra-low-noise LDOs or complex multi-stage filtering. |
| Factory-programmed frequency | 100 MHz pre-configured at wafer test; avoids field programming complexity and yield loss. |
| Industrial temperature range | –40°C to +85°C operation ensures stability in base station, server, and industrial control environments. |
| OE-controlled output disable | 50 µs enable/disable latency allows dynamic clock gating in power-managed systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HCSL oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMK60E2-100M00SIAT | LVPECL output (not HCSL); same 100 MHz, ±50 ppm, 150 fs jitter, 3.3-V supply. | Requires 50-Ω AC-coupled termination to VCCO–2 V; incompatible with HCSL-receiver-only FPGA banks. | Select only if target FPGA supports LVPECL and board layout accommodates higher power (110 mA vs. 105 mA) and different termination. |
| Si510-100M000XMS | Programmable I²C oscillator; 100 MHz HCSL; ±20 ppm stability; 115 fs jitter; 2.5/3.3-V dual supply. | Field-configurable frequency and output format; supports spread-spectrum modulation; requires I²C host initialization. | Choose when flexibility across multiple clock frequencies or future firmware updates is required; adds BOM and firmware overhead. |
Compared with LMK60I2-100M00SIAT, the LMK60E2-100M00SIAT demands different termination and consumes slightly more current, while the Si510 offers programmability at the cost of added system complexity and reduced jitter margin.

FAQ
What is the recommended power supply bypassing scheme for LMK60I2-100M00SIAT?
TI specifies a three-capacitor network: 10 µF (bulk), 1 µF (mid-frequency), and 0.1 µF (high-frequency), all placed as close as possible to the VDD pin with short, low-inductance traces to the GND pad. Use 0201 or 0402 case sizes and connect the ground side of each capacitor directly to the exposed thermal pad via multiple vias.
Can LMK60I2-100M00SIAT be used with LVDS or LVPECL receivers?
No - it is factory-configured exclusively for HCSL output. The internal driver circuitry, voltage levels (VOH/VOL), and common-mode characteristics are optimized for 50-Ω HCSL loads. Connecting to LVDS or LVPECL receivers will result in incorrect logic levels, excessive current draw, or undefined behavior.
Does LMK60I2-100M00SIAT require external configuration or programming after soldering?
No - it is fully factory-programmed with 100 MHz HCSL output, ±50 ppm tolerance, and default OE behavior. No I²C, SPI, or pin-strapping is supported. Configuration is immutable post-manufacture, ensuring consistent performance across production lots.
How does the OE pin behave during power-up, and what is its default state?
The OE pin has an internal pull-up resistor to VDD, so the output is enabled by default upon power-up. When OE is driven low (≤0.6 V), both OUTP and OUTN enter high-impedance state within 50 µs. No external pull-up is required, but system-level reset sequencing must ensure OE remains high until VDD stabilizes above 3.135 V.
