Product details
Overview
XLH536050.000000I from Renesas Electronics is a 50.000000 MHz ultra-precision LVDS-output crystal oscillator (XO) in a 5.0 × 3.2 mm JS6 package, delivering ±25 ppm frequency stability over –40°C to +85°C, 750 fs typical phase jitter (12 kHz–20 MHz), and 3.3 V supply operation - deployed in high-speed SerDes clocking for telecom infrastructure and FPGA timing systems.
For engineers reviewing the XLH536050.000000I datasheet, XLH536050.000000I pinout, XLH536050.000000I application, or XLH536050.000000I equivalent, this page provides verified technical context, validated pin functions, real-world use cases, and confirmed alternative options for industrial-grade low-jitter timing design.
Technical Context
The XLH536050.000000I implements a quartz-based PLL architecture with a 3rd-order Delta-Sigma modulator to suppress close-in and broadband phase noise. Its LVDS output stage delivers differential swing of 0.6 V (typ.) into 100 Ω loads, with rise/fall times ≤400 ps and duty cycle maintained between 47%–53% across temperature.
This XO variant uses an internal ASIC optimized for noise reduction, achieving jitter performance comparable to bulk quartz and SAW oscillators. It operates without external tuning voltage (VCXO functionality excluded), and features enable/disable control on Pin 1 with 70% VDD logic threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 50.000000 MHz - exact nominal frequency, stable across full operating range |
| Phase Jitter (12 kHz–20 MHz) | 750 fs typical - enables compliance with PCIe Gen4/Gen5, 10G/25G Ethernet, and CPRI jitter budgets |
| Frequency Stability | ±25 ppm over –40°C to +85°C - includes aging, temp, voltage, and load effects per spec footnote 2 |
| Supply Voltage | 3.3 V ±5% - supports standard industrial power rails; IDD = 32 mA typical at 50 MHz |
| Output Type | LVDS - differential signaling with 100 Ω termination requirement; complementary outputs (OUT/OUT2) |
| Package | JS6: 5.0 × 3.2 × 1.2 mm - RoHS-compliant surface-mount ceramic SMD package |
| Start-up Time | ≤10 ms - time from VDD reaching minimum to valid clock output |
Pinout & Package
XLH536050.000000I uses the JS6 6-pin ceramic SMD package (5.0 × 3.2 × 1.2 mm), designed for reflow soldering per JEDEC J-STD-020. Pin 1 is Enable/Disable (E/D); Pin 3 is GND; Pin 6 is VDD. A 0.01 μF bypass capacitor is required between Pins 6 and 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E/D (Enable/Disable) | Active-low control: logic low disables output; pulled high internally; compatible with 3.3 V CMOS logic |
| 2 | NC | No connect - not bonded; must be left floating or grounded per layout best practice |
| 3 | GND | Power ground reference - requires low-inductance connection to system ground plane |
| 4 | OUT | Differential LVDS output positive - 0.6 V typical swing into 100 Ω load |
| 5 | OUT2 | Differential LVDS output negative - complementary to OUT; both active simultaneously |
| 6 | VDD | 3.3 V ±5% supply input - requires local 0.01 μF ceramic decoupling to Pin 3 |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low phase jitter | 750 fs typical (12 kHz–20 MHz) - meets stringent SerDes and ADC sampling clock requirements |
| Dual complementary LVDS outputs | OUT and OUT2 provide true differential signaling with matched delay and skew <5 ps |
| Industrial temperature range | –40°C to +85°C operation with ±25 ppm stability - qualified for base station and edge compute environments |
| Fast enable/disable response | ≤100 ns output enable/disable time - supports dynamic power gating in low-power systems |
| Low EMI emission profile | LVDS output with controlled edge rates (≤400 ps) and internal noise-reduction ASIC - reduces board-level filtering needs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-jitter XO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-50M0000-AG | 700 fs phase jitter (12 kHz–20 MHz); 3.3 V LVPECL output; same 5.0 × 3.2 mm package | Limited to ±20 ppm stability over –40°C to +85°C; no LVDS option | Select when LVPECL interface and tighter stability are prioritized over differential common-mode rejection |
| AK2-50.0000T | 850 fs phase jitter; 2.5 V LVDS; ±25 ppm over –40°C to +85°C; 3.2 × 2.5 mm package | Lower supply voltage and smaller footprint; higher current draw at 50 MHz (36 mA vs. 32 mA) | Select when board space is constrained and 2.5 V rail is available; verify thermal derating for 70°C ambient |
Compared with XLH536050.000000I, Si510-50M0000-AG offers marginally lower jitter but requires LVPECL termination and lacks common-mode noise immunity, while AK2-50.0000T saves board area at the cost of higher power density and reduced voltage headroom.

FAQ
What is the operating temperature range for XLH536050.000000I?
XLH536050.000000I is rated for industrial operation from –40°C to +85°C, with frequency stability guaranteed at ±25 ppm across this full range. This specification includes contributions from temperature variation, supply voltage change, load variation, aging, shock, and vibration per datasheet footnote 2.
Does XLH536050.000000I support LVCMOS output?
No, XLH536050.000000I is an LVDS-output device. The "H" in the part number denotes LVDS configuration. LVCMOS variants exist in the XL family (e.g., XLJ-series), but XLH536050.000000I specifically implements differential LVDS outputs (OUT and OUT2) with 100 Ω termination requirement.
What is the recommended bypass capacitor for XLH536050.000000I?
A 0.01 μF ceramic capacitor is required between VDD (Pin 6) and GND (Pin 3) to minimize power supply line noise. This value is explicitly specified in the Renesas XL datasheet for both XO and VCXO variants and must be placed as close as possible to the pins.
Is XLH536050.000000I a VCXO or XO device?
XLH536050.000000I is an XO (crystal oscillator), not a VCXO. The "H" prefix and absence of "V" in the ordering code confirm it lacks voltage-controlled tuning capability. Its frequency is fixed at 50.000000 MHz with no Vc pin - Pin 1 is E/D, not voltage control.
What package type does XLH536050.000000I use?
XLH536050.000000I uses the JS6 package: a 5.0 × 3.2 × 1.2 mm ceramic surface-mount oscillator package. This is confirmed by the "5" digit in the part number (position 5), which maps to the 5.0 × 3.2 mm outline per Renesas ordering information tables.
