Product details
Overview
LMK60E2-100M00SIAT from Texas Instruments is a factory-programmed, low-jitter LVPECL 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 in industrial temperature range (–40°C to +85°C) and serves as a high-stability clock reference for FPGA and processor interfaces in network infrastructure.
For engineers reviewing the LMK60E2-100M00SIAT datasheet, LMK60E2-100M00SIAT pinout, LMK60E2-100M00SIAT application, or LMK60E2-100M00SIAT equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for timing-critical embedded and communications systems.
Technical Context
The LMK60E2-100M00SIAT integrates a high-performance PLL-based oscillator core with internal power conditioning to suppress supply noise, enabling stable 100 MHz LVPECL output without external crystal or loop filter components. Its architecture supports deterministic start-up within 10 ms and fast output enable/disable (<50 µs) via OE control.
It uses a fixed-output configuration-pre-programmed for 100 MHz LVPECL-eliminating configuration registers or I²C/SPI interface overhead. The device's differential output pair (OUTP/OUTN) is optimized for 50-Ω termination and compatible with standard LVPECL receiver inputs in high-speed serial links and synchronous logic domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 100 MHz - factory-trimmed, no user programming required; directly usable as system reference clock. |
| Jitter (RMS) | 150 fs (12 kHz–20 MHz) - enables clean sampling in high-speed SerDes (e.g., PCIe Gen3, 10G Ethernet PHY). |
| Frequency Tolerance | ±50 ppm - includes initial calibration, temperature drift (–40°C to +85°C), voltage variation, solder reflow, and 5-year aging at 40°C. |
| Output Format | LVPECL - delivers 700–1200 mV differential swing into 50-Ω loads; compatible with TI, IDT, and Renesas LVPECL receivers. |
| Supply Voltage | 3.3 V ±5% - requires only one rail; supports standard industrial power delivery networks with minimal decoupling (10 µF / 1 µF / 0.1 µF). |
| PSRR | –60 dBc @ 50 kHz–1 MHz - rejects board-level switching noise without additional LDO filtering. |
| Operating Temp | –40°C to +85°C - qualified per JEDEC JESD22-A104; suitable for uncontrolled ambient environments in telecom line cards. |
Pinout & Package
LMK60E2-100M00SIAT uses a 7.0 mm × 5.0 mm, 6-pin QFM (SIA) package with exposed thermal pad, pin-compatible with industry-standard 7050 XO footprints. The package supports automated placement and reflow per J-STD-020 MSL Level-3 (260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Digital control input | LVCMOS-compatible output enable with internal pullup; drives output to high-impedance when low (tOE-DIS = 50 µs). |
| 2 (NC) | No-connect | Unbonded die pad; must remain floating-no routing or stitching to ground/power. |
| 3 (GND) | Analog/digital ground | Primary return path for oscillator core and output drivers; requires ≥3 thermal vias to inner ground plane. |
| 4 (OUTN) | Differential output (negative) | LVPECL-compliant negative leg of 100 MHz clock; routed with matched length and 100-Ω differential impedance. |
| 5 (OUTP) | Differential output (positive) | LVPECL-compliant positive leg; forms 100 MHz differential pair with OUTN for EMI reduction and common-mode noise rejection. |
| 6 (VDD) | Power supply | 3.3-V analog supply; bypassed externally with 10 µF, 1 µF, and 0.1 µF capacitors placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Low-phase-noise PLL core | 150 fs RMS jitter enables <0.1 UI jitter margin in 10 Gbps NRZ links without retiming. |
| Integrated power conditioning | –60 dBc PSRR eliminates need for dedicated low-noise LDO, reducing BOM count and PCB area. |
| Factory-programmed frequency | 100 MHz LVPECL output shipped fully calibrated-no field programming or configuration required. |
| Industrial-grade thermal design | ΨJB = 49.0 °C/W with 3+ thermal vias ensures junction stays ≤105°C at 87°C PCB temperature under full load. |
| Fast output control | 50 µs OE response time allows dynamic clock gating in power-managed subsystems (e.g., FPGA partial reconfiguration). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMK60E2-100M00SIAR | Same electrical specs and pinout; differs only in packaging (2500-unit tape-and-reel vs. 250-unit small reel). | Identical functional use; selected for high-volume production runs rather than prototyping or low-MOQ builds. | Choose SIAR for cost-optimized manufacturing; SIAT for engineering validation and small-batch integration. |
| Si510-100.000M | 100 MHz LVDS output (not LVPECL); ±20 ppm stability; programmable via I²C; higher 225 fs jitter. | Requires level-shifting for LVPECL receivers; suited for designs needing field-adjustable frequency or multi-output flexibility. | Select only if LVDS interface and programmability outweigh jitter and supply noise immunity trade-offs. |
Compared with LMK60E2-100M00SIAT, the SIAR variant offers identical performance in bulk packaging, while Si510-100.000M trades lower jitter and superior PSRR for programmability and LVDS compatibility-making it less suitable for noise-sensitive, fixed-frequency 10G+ applications.

FAQ
What is the recommended power supply decoupling for LMK60E2-100M00SIAT?
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. Capacitors should be 0201 or 0402 size, mounted on the component side, and grounded via multiple vias to minimize impedance and ensure stable 3.3-V operation under dynamic load.
Can LMK60E2-100M00SIAT be used with LVDS receivers?
No-LMK60E2-100M00SIAT is factory-configured for LVPECL output only. Its output stage is not compatible with LVDS input thresholds or termination schemes. For LVDS, select LMK60I2-100M00SIAT (HCSL) or LMK60E2-100M00SIAT's LVDS-capable sibling variants, which have different internal driver circuitry and output voltage levels.
Does LMK60E2-100M00SIAT require external configuration or programming?
No. It is a factory-programmed oscillator with fixed 100 MHz LVPECL output. No I²C, SPI, or pin-strapping configuration is needed. The device powers up and begins outputting a valid clock within 10 ms after VDD reaches 3.135 V, with no firmware or host initialization required.
How does the OE pin behave during power-up?
The OE pin has an internal pullup, so the output is enabled by default at power-on. If OE is held low during VDD ramp, the outputs remain in high-impedance state until OE rises above VIH (1.4 V). Output enable timing is guaranteed at 50 µs after OE crosses VIH, independent of VDD ramp rate or temperature.
