Product details
Overview
XLH736004.000000I from Renesas Electronics is an ultra-precision 4.000000 MHz LVDS-output crystal oscillator (XO) in a 7.0 × 5.0 × 1.3 mm JU6 package, with ±20 ppm frequency stability over -20°C to +70°C, 750 fs typical phase jitter (12 kHz–20 MHz), and 3.3 V supply. It serves as a low-noise clock source for high-speed serial interfaces in telecom and datacom equipment.
For engineers reviewing the XLH736004.000000I datasheet, XLH736004.000000I pinout, XLH736004.000000I application, or XLH736004.000000I equivalent, this page delivers verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options - all grounded in Renesas' official XL family documentation.
Technical Context
The XLH736004.000000I implements a quartz-based PLL architecture with a 3rd-order Delta-Sigma modulator to suppress phase noise, achieving jitter performance comparable to bulk quartz and SAW oscillators. Its core ASIC targets noise reduction across wide bandwidths without requiring external loop filters.
This XO variant supports LVDS differential output with complementary OUT/OUT2 signals, operates at 3.3 V ±5%, and features an enable/disable control on Pin 1 (E/D). It does not support voltage control (no VCXO functionality) and excludes the 3.2 × 2.5 mm package option.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 4.000000 MHz - precisely trimmed and factory-set; no user tuning required. |
| Phase Jitter (12 kHz–20 MHz) | 750 fs typical - enables compliance with stringent SerDes clocking requirements (e.g., PCIe Gen4/5, Ethernet 25G+). |
| Frequency Stability | ±20 ppm over -20°C to +70°C - includes aging, temperature, voltage, and load effects per Renesas specification. |
| Supply Voltage | 3.3 V ±5% - requires stable low-noise rail; bypass capacitor (0.01 µF) mandatory between Pin 6 (VDD) and Pin 3 (GND). |
| Output Type | LVDS - differential signaling with 100 Ω load impedance; supports 47–53% duty cycle and <400 ps rise/fall times. |
| Package | JU6 (7.0 × 5.0 × 1.3 mm) - industry-standard 6-pin surface-mount ceramic package with lead-free finish. |
| Start-up Time | ≤10 ms - time from VDD reaching minimum level to valid output; critical for power-managed systems. |
Pinout & Package
JU6 package: 7.0 × 5.0 × 1.3 mm ceramic SMD, 6-pin, RoHS-compliant, reflow-compatible (JEDEC J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E/D (Enable/Disable) | Active-low control: logic low disables output; internally pulled high; must be tied high or driven for normal operation. |
| 2 | NC | No connect - left floating per datasheet; not bonded or functional. |
| 3 | GND | Ground reference for all internal circuitry and output termination; requires low-inductance connection to system ground plane. |
| 4 | OUT | LVDS positive output - paired with OUT2 for true differential signaling; 100 Ω differential load required. |
| 5 | OUT2 | LVDS complementary (negative) output - used only with LVDS/LVPECL; NC for LVCMOS variants. |
| 6 | VDD | 3.3 V power supply input - bypassed externally with 0.01 µF capacitor to GND (Pin 3) to suppress supply noise. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low phase jitter | 750 fs typical (12 kHz–20 MHz) - directly reduces bit error rate in high-speed serial links. |
| Differential LVDS output | Guaranteed 47–53% duty cycle and <400 ps edge rates - ensures signal integrity in point-to-point clock distribution. |
| Factory-trimmed stability | ±20 ppm over -20°C to +70°C - eliminates need for field calibration or compensation circuits. |
| Fast start-up | ≤10 ms - enables rapid system boot and low-power wake-up sequences without clock-related delays. |
| Robust ESD protection | 1000 V HBM - enhances reliability during handling and board assembly in industrial environments. |
Applications
| 10G/25G Ethernet PHY Clocking | PCIe Gen4 Reference Clock |
|---|---|
|

IC Role / Device Role / Timing Role: Low-jitter system clock source synchronizing SERDES lanes and MAC timing blocks. Use Value: 750 fs phase jitter meets IEEE 802.3bj/ck jitter budgets, reducing link training failures and improving BER margin. |
Use Scenario: Delivering the 100 MHz reference clock to PCIe Gen4 root complex or endpoint controllers (e.g., Intel PCH, AMD X399). IC Role / Device Role / Timing Role: Primary timing reference for PCIe controller PLLs and SerDes CDR circuits. Use Value: ±20 ppm stability and fast start-up ensure reliable enumeration and compliance with PCIe Gen4 clock tolerance (±300 ppm total, including spread spectrum). |
| Industrial PLC Backplane Timing | Medical Imaging Data Acquisition Clock |
|
Use Scenario: Generating synchronized sampling clocks across multiple I/O modules in modular PLC backplanes (e.g., Siemens SIMATIC ET 200SP). IC Role / Device Role / Timing Role: Centralized low-drift clock distributor ensuring deterministic inter-module communication timing. Use Value: -20°C to +70°C operating range and ±20 ppm stability maintain timing accuracy under variable cabinet thermal conditions. |
Use Scenario: Driving ADC sampling clocks in ultrasound or MRI front-end digitizers requiring precise multi-channel phase alignment. IC Role / Device Role / Timing Role: Master clock source for high-resolution analog-to-digital conversion subsystems. Use Value: LVDS differential output minimizes common-mode noise coupling into sensitive analog signal paths, preserving SNR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar crystal oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-4-10-4M000000 | 4.000000 MHz, ±20 ppm, LVDS, 5.0 × 3.2 mm (JS6); 850 fs phase jitter (12 kHz–20 MHz); 2.5 V/3.3 V selectable. | Smaller footprint; higher jitter; lacks extended temp grade (-40°C to +85°C available but not standard for this variant). | Preferred when board space is constrained and jitter margin allows ≥850 fs. |
| AK2-4.0000MHZ-EK | 4.000000 MHz, ±25 ppm, LVDS, 7.0 × 5.0 mm (JU6); 950 fs phase jitter; 3.3 V only; -40°C to +85°C rating. | Same package size; looser stability; higher jitter; wider temp range; no enable/disable pin. | Selected when industrial temperature range is mandatory and ±25 ppm stability suffices. |
Compared with XLH736004.000000I, the Si510 offers smaller size at the cost of 100 fs higher jitter and no E/D pin, while the AK2 trades ±20 ppm stability and 750 fs jitter for guaranteed -40°C to +85°C operation - making XLH736004.000000I optimal for commercial-temp, jitter-critical designs where board area is not limiting.

FAQ
What is the operating temperature range for XLH736004.000000I?
XLH736004.000000I is rated for -20°C to +70°C operation, with frequency stability specified as ±20 ppm across that full range. This "extended commercial" grade is confirmed in Renesas' Ordering Information (XO) table using the "X" temperature code, and excludes the -40°C to +85°C or -40°C to +105°C variants.
Does XLH736004.000000I support voltage-controlled operation (VCXO mode)?
No, XLH736004.000000I is an XO (fixed-frequency crystal oscillator), not a VCXO. Its part number contains "H" (LVDS output) and "X" (temperature code), but lacks the "V" suffix used in VCXO ordering codes. Pin 1 is E/D (enable/disable), not Vc - confirming it has no voltage control capability.
What is the recommended power supply bypassing for XLH736004.000000I?
Renesas specifies a 0.01 µF ceramic bypass capacitor between Pin 6 (VDD) and Pin 3 (GND), placed as close as possible to the device. This is mandatory to minimize power supply line noise, which directly impacts phase jitter performance - especially critical given the 750 fs target.
Can XLH736004.000000I drive a 50 Ω single-ended load?
No. XLH736004.000000I is configured for LVDS output, requiring a 100 Ω differential load across OUT and OUT2. Driving a 50 Ω single-ended load violates its AC specifications, degrades signal integrity, and may cause excessive current draw or timing violations.
Is the XLH736004.000000I pin-compatible with other XL-series oscillators in the JU6 package?
Yes - all XL-series devices in the JU6 (7.0 × 5.0 mm) package share identical pinout: Pin 1 = E/D, Pin 2 = NC, Pin 3 = GND, Pin 4 = OUT, Pin 5 = OUT2, Pin 6 = VDD. This allows drop-in replacement within the same output type and voltage family, provided frequency, stability, and jitter requirements align.
