Product details
Overview
XLH736025.000000I from Renesas Electronics is an ultra-precision 25.000000 MHz VCXO (Voltage-Controlled Crystal Oscillator) in a 7.0 × 5.0 × 1.3 mm JU6 package, delivering ±50 ppm APR frequency stability over -40°C to +85°C, 750–890 fs typical phase jitter (12 kHz–20 MHz), and LVDS output with 3.3 V supply. It serves as a low-noise clock source for high-speed serial interfaces including PCIe Gen4/5 and 10G/25G Ethernet PHYs.
For engineers reviewing the XLH736025.000000I datasheet, XLH736025.000000I pinout, XLH736025.000000I application, or XLH736025.000000I equivalent, this page provides verified pin functions, real-world jitter performance at 25 MHz, voltage control linearity (85 ppm/V), thermal stability across industrial temperature range, and validated alternatives for timing-critical embedded and communications systems.
Technical Context
The XLH736025.000000I implements a quartz-based PLL architecture with a 3rd-order Delta-Sigma modulator to suppress close-in and broadband phase noise-achieving jitter performance comparable to bulk quartz and SAW oscillators. Its VCXO mode enables fine frequency tuning via analog voltage input (Vc) across 0.5 VDC to VDD.
It supports LVDS differential signaling with guaranteed 47–53% duty cycle, <400 ps rise/fall times, and 100 Ω differential load compatibility. The device integrates internal pull-up on E/D pin and requires no external termination for LVDS operation, simplifying board-level design while maintaining signal integrity at 25 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
XLH736025.000000I uses the JU6 package: 7.0 × 5.0 × 1.3 mm surface-mount ceramic SMD oscillator module with 6-pin configuration. Pin 1 is Vc (voltage control), Pin 2 is E/D (enable/disable), Pin 3 is GND, Pin 4 is OUT, Pin 5 is OUT2 (complementary LVDS output), and Pin 6 is VDD. A 0.01 µF bypass capacitor is required between Pins 6 (VDD) and 3 (GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vc | Analog voltage control input; 0.5 VDC to VDD range sets output frequency deviation within ±50 ppm APR window. |
| 2 | E/D | Enable/Disable control; pulled high internally; logic low disables outputs (high-impedance state). |
| 3 | GND | Signal and power ground reference; must be connected to low-impedance PCB ground plane. |
| 4 | OUT | Differential LVDS output positive terminal; 350 mV swing into 100 Ω load; referenced to VOS ≈ 1.3 V (3.3 V supply). |
| 5 | OUT2 | Differential LVDS output negative terminal; complementary to OUT; enables true differential signaling and common-mode noise rejection. |
| 6 | VDD | 3.3 V ±5% power supply; maximum current draw 37 mA at 25 MHz; requires local 0.01 µF ceramic decoupling. |
