Product details
Overview
XUH535003.686000I from Renesas Electronics is a quartz-based PLL oscillator delivering 3.686 MHz LVCMOS output with ±25 ppm frequency stability over -40°C to +85°C, 3.3V supply, and 5.0 × 3.2 mm JS6 package. It features 300 fs typical phase jitter (12 kHz–20 MHz), 10 ms start-up time, and integrated enable/disable control for power-sensitive timing applications in industrial communications and embedded controllers.
For engineers reviewing the XUH535003.686000I datasheet, XUH535003.686000I pinout, XUH535003.686000I application, or XUH535003.686000I equivalent, this page provides verified technical context, validated pin functions, confirmed LVCMOS timing behavior, and real-world substitution guidance - all grounded in Renesas' official XU family documentation and ordering specifications.
Technical Context
The XUH535003.686000I implements a patented one-time-programmable (OTP) PLL architecture that locks a low-noise quartz reference to generate precise integer or fractional output frequencies from 16 kHz to 1500 MHz. Its internal VCO operates under closed-loop control with programmable loop bandwidth optimized for low integrated jitter.
This device supports LVCMOS output with rail-to-rail swing, 10%–90% rise/fall times ≤3 ns, 45–55% duty cycle at 3.686 MHz, and E/D pin-controlled output enable/disable with 100 ns response. It requires no external configuration interface - all settings are factory-programmed into OTP memory with infinite shelf life.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiT8008BI-13-33E-3.686000X | MEMS-based; ±20 ppm stability; 3.3 V; same 5.0 × 3.2 mm footprint but different pinout (4-pin) | Higher shock/vibration tolerance; no quartz aging; slightly higher 600 fs jitter (12 kHz–20 MHz) | Choose for harsh mechanical environments where quartz fragility is a concern; verify PCB layout compatibility. |

FAQ
What is the exact output frequency and stability of the XUH535003.686000I?
The XUH535003.686000I is factory-programmed to deliver exactly 3.686000 MHz with ±25 ppm frequency stability over the full industrial temperature range (-40°C to +85°C), including effects of voltage variation, load change, aging, and mechanical stress. This specification is guaranteed per Renesas' AC Electrical Characteristics Table 12 and Ordering Information decoding for "I" temperature grade and "6" precision code.
Does the XUH535003.686000I require external configuration or I²C programming?
No, the XUH535003.686000I does not require external configuration. All parameters - including 3.686000 MHz output, LVCMOS interface, 3.3 V supply, ±25 ppm stability, and -40°C to +85°C operation - are permanently stored in one-time-programmable (OTP) memory during manufacturing. The device powers up ready to operate with no initialization sequence or host interaction needed.
What is the function of Pin 5 (OUT2) on the XUH535003.686000I?
Pin 5 (OUT2) is the complementary LVCMOS output terminal. For the XUH535003.686000I - configured as standard LVCMOS - OUT2 remains active but is not used; it mirrors OUT with 180° phase shift. Renesas specifies that OUT2 should be left floating or terminated per layout guidelines, as it is not disabled in LVCMOS mode and may affect signal integrity if improperly routed.
Can the XUH535003.686000I be used with a 2.5 V or 1.8 V supply?
No, the XUH535003.686000I is specified exclusively for 3.3 V ±5% operation. Its part number encoding ("5" in position 4) explicitly denotes 3.3 V supply; using 2.5 V or 1.8 V will result in failure to start, invalid output levels, or undefined behavior. For lower-voltage alternatives, Renesas offers distinct part numbers such as XUH525xxx or XUH515xxx.
Is a bypass capacitor required for the XUH535003.686000I, and where should it be placed?
Yes, a 0.01 μF ceramic bypass capacitor is mandatory between Pin 6 (VDD) and Pin 3 (GND), as explicitly stated in the Renesas XU datasheet Pin Assignments section. It must be placed within 2 mm of the pins to minimize power supply line noise and ensure stable PLL operation - omission or poor placement risks increased jitter or intermittent startup failure.
