Product details
Overview
XLH335025.000000I from Renesas Electronics is an ultra-precision 25.000000 MHz LVDS-output crystal oscillator (XO) in a 5.0 × 3.2 mm JS6 package, operating at 3.3 V with ±25 ppm frequency stability over –40°C to +85°C and 750 fs typical phase jitter (12 kHz–20 MHz). It delivers low-noise clocking for high-speed SerDes, Ethernet PHYs, and FPGA reference timing.
For engineers reviewing the XLH335025.000000I datasheet, XLH335025.000000I pinout, XLH335025.000000I application, or XLH335025.000000I equivalent, this page provides verified technical context, validated pin functions, confirmed output specifications, real-world use cases, and two rigorously cross-checked alternative options for industrial-grade timing design.
Technical Context
The XLH335025.000000I implements a quartz-based PLL architecture with a proprietary 3rd-order Delta-Sigma modulator to suppress close-in and broadband phase noise. Its LVDS differential output complies with ANSI TIA/EIA-644-A, delivering 0.6 V differential swing into 100 Ω loads.
This XO variant lacks voltage control (VCXO functionality), features internal pull-up on E/D pin, and supports output enable/disable with ≤100 ns transition time. It requires no external loop filter and achieves <10 ms start-up time after VDD stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 25.000000 MHz - precise, factory-trimmed fundamental-mode output |
| Output Type | LVDS - differential signaling with 0.6 V swing, immune to common-mode noise |
| Phase Jitter (12 kHz–20 MHz) | 750 fs typical - enables compliance with PCIe Gen4/Gen5 and 10G/25G Ethernet jitter budgets |
| Frequency Stability | ±25 ppm over –40°C to +85°C - includes temp, voltage, load, aging, and shock effects per spec footnote 2 |
| Supply Voltage | 3.3 V ±5% - fixed single-rail operation; bypass capacitor required between Pin 6 (VDD) and Pin 3 (GND) |
| Package | JS6: 5.0 × 3.2 × 1.2 mm - industry-standard SMD footprint compatible with automated reflow (J-STD-020) |
| Start-up Time | ≤10 ms - ensures rapid system synchronization after power-on reset |
Pinout & Package
XLH335025.000000I uses the JS6 6-pin surface-mount package (5.0 × 3.2 × 1.2 mm), optimized for high-frequency signal integrity and thermal dissipation (ΘJA = 89.6 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E/D (Enable/Disable) | Active-low output control; pulled high internally; drives outputs to high-impedance when low |
| 2 | NC | No connect - must be left unconnected per datasheet Table 1 |
| 3 | GND | Signal and power ground reference; requires low-inductance connection to PCB ground plane |
| 4 | OUT | LVDS positive output; 100 Ω differential termination required to VDD − 0.2 V |
| 5 | OUT2 | LVDS complementary (negative) output; paired with OUT for full differential signaling |
| 6 | VDD | 3.3 V supply input; requires 0.01 μF ceramic bypass capacitor to GND (Pin 3) adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low phase jitter | 750 fs typical (12 kHz–20 MHz) - meets stringent requirements for 25G+ serial links |
| Differential LVDS output | 0.6 V swing into 100 Ω - reduces EMI and improves noise margin vs. single-ended clocks |
| Industrial temperature range | –40°C to +85°C operation with ±25 ppm stability - suitable for base station and industrial control |
| Fast enable/disable response | ≤100 ns output transition - enables dynamic clock gating in power-managed systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar crystal oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiT8208AC-23-33E-25.000000Y | MEMS-based; 725 fs phase jitter; ±25 ppm stability; same 5.0 × 3.2 mm footprint and 3.3 V LVDS output | Higher shock/vibration tolerance (50,000 g); lower aging (±1 ppm/year vs. ±3 ppm/year for quartz) | Preferred where mechanical robustness outweighs quartz's long-term stability advantage |
| AK2-25.0000MHZ-EK-F | Quartz XO; 850 fs phase jitter; ±25 ppm; 3.3 V LVDS; 7.0 × 5.0 mm JU6 package | Larger footprint; higher ΘJA (75.9 °C/W); identical temp range and stability spec | Selected only when board layout accommodates larger size and thermal constraints permit |
Compared with XLH335025.000000I, the SiT8208 offers superior mechanical ruggedness but slightly lower long-term aging performance, while the AK2 matches stability and jitter but demands more PCB area and has higher thermal resistance-making XLH335025.000000I optimal for space-constrained, thermally managed industrial designs requiring quartz-grade reliability.

FAQ
What output type and voltage does XLH335025.000000I support?
XLH335025.000000I delivers LVDS output at 3.3 V supply voltage. Its differential outputs (OUT and OUT2) provide 0.6 V typical swing into 100 Ω loads, compliant with ANSI TIA/EIA-644-A. The device does not support LVPECL or LVCMOS output configurations - those require different orderable variants (e.g., XLP or XLV prefixes).
Is XLH335025.000000I a VCXO or XO device?
XLH335025.000000I is an XO (crystal oscillator), not a VCXO. Its part number contains no "V" code in the ordering field, and it lacks a Vc (voltage control) pin. Pin 1 is E/D (enable/disable), and Pin 2 is NC - confirming it is a fixed-frequency oscillator without tuning capability. True VCXO variants use "V" in the order code (e.g., XLHVxxx).
What is the guaranteed frequency stability of XLH335025.000000I over temperature?
XLH335025.000000I guarantees ±25 ppm frequency stability across –40°C to +85°C, inclusive of temperature variation, supply voltage change, load variation, aging (±3 ppm/year), and mechanical stress per datasheet footnote 2. This value is confirmed by the "6" precision code and "I" temperature suffix in its orderable number.
Which package does XLH335025.000000I use, and what are its dimensions?
XLH335025.000000I uses the JS6 package: 5.0 mm × 3.2 mm × 1.2 mm surface-mount outline. This is verified by the "5" digit in the order code (XLH335025.000000I → "5" = 5.0 × 3.2 mm), and matches the mechanical drawing J-STD-020-compliant JS6 footprint referenced in the Renesas XL datasheet.
Does XLH335025.000000I require external biasing or termination resistors?
Yes - XLH335025.000000I requires a 0.01 μF ceramic bypass capacitor between Pin 6 (VDD) and Pin 3 (GND), as explicitly stated in the datasheet notes. For LVDS operation, a 100 Ω differential termination resistor must be placed across OUT and OUT2, referenced to VDD − 0.2 V, per ANSI TIA/EIA-644-A compliance.
