Product details
Overview
8N4SV76FC-0096CDI from Integrated Device Technology is an LVDS frequency-programmable VCXO with factory-programmed output at 156.25 MHz, ±50 ppm total stability (Option E), and 2.5 V supply. It delivers 0.53 ps RMS phase jitter (12 kHz–20 MHz), operates from –40°C to +85°C, and uses fourth-generation FemtoClock® NG PLL architecture for low-noise synthesis in wireless infrastructure timing systems.
For engineers reviewing the 8N4SV76FC-0096CDI datasheet, 8N4SV76FC-0096CDI pinout, 8N4SV76FC-0096CDI application, or 8N4SV76FC-0096CDI equivalent, key selection criteria include its LVDS differential output, programmable pull range (±4.5 to ±754.5 ppm), 218 Hz frequency resolution, and industrial-grade thermal performance in 5 mm × 7 mm ceramic packaging.
Technical Context
The 8N4SV76FC-0096CDI integrates a 114.285 MHz third-overtone crystal oscillator driving a fractional-N PLL with 7-bit integer (MINT) and 18-bit fractional (MFRAC) feedback dividers, enabling precise frequency synthesis across two bands: 15.476–866.67 MHz and 975–1300 MHz. Its VCO operates at 1950–2600 MHz before post-division.
Control is implemented via LVCMOS/LVTTL-compatible nOE (pin 2) for output enable/disable and VC (pin 1) for analog tuning voltage input (0–VDD), with oscillator gain configurable from 7.57 to 477.27 ppm/V (3.3 V) or 10–630 ppm/V (2.5 V). The device uses delta-sigma modulation for noise shaping and achieves <1 ps cycle-to-cycle jitter.
Key Specifications

Pinout & Package
6-lead ceramic VFQFN package, 5 mm × 7 mm × 1.55 mm, RoHS 6-compliant, with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-PROG | Programmable I²C interface; wider pull range (±100 to ±200 ppm); higher phase noise (0.75 ps typical @156.25 MHz) | Requires external MCU for configuration; better suited for systems needing field-adjustable frequency. | Select when dynamic reprogramming is required; avoid if pin count or jitter-critical paths constrain design. |
| AK2-156.250MHZ-E | Fixed-frequency LVDS XO (no VC input); ±20 ppm stability; 0.45 ps RMS jitter; same 5×7 mm footprint | No tuning capability; optimized for static clock trees where VCXO flexibility is unnecessary. | Choose for cost-sensitive, non-servo applications where absolute stability outweighs tunability. |
Compared with 8N4SV76FC-0096CDI, Si510-PROG offers configurability at the expense of higher jitter and added firmware overhead, while AK2-156.250MHZ-E trades VCXO functionality for superior phase noise and lower BOM complexity in fixed-clock deployments.

FAQ
What is the factory-programmed output frequency of the 8N4SV76FC-0096CDI?
The 8N4SV76FC-0096CDI is factory-programmed to 156.25 MHz, a standard reference frequency used in Ethernet, OTN, and CPRI applications. This value is permanently stored in on-chip ROM and cannot be altered in the field. The device maintains this frequency with ±50 ppm total stability over temperature, aging, and initial calibration - verified per IDT's FemtoClock NG Ceramic-Package XO and VCXO Ordering Product Information document.
Does the 8N4SV76FC-0096CDI support both 2.5 V and 3.3 V supply voltages?
No - the 8N4SV76FC-0096CDI is specifically configured for 2.5 V ±5% operation, as indicated by the "F" in its order code (8N4SV76FC-0096CDI). While the underlying IDT8N4SV76 platform supports dual-supply variants, this exact part number is rated only for 2.5 V. Applying 3.3 V exceeds absolute maximum ratings and may cause permanent damage. Power supply current is specified at 135–170 mA under these conditions.
How is the VCXO pull range configured for the 8N4SV76FC-0096CDI?
The 8N4SV76FC-0096CDI has a factory-programmed absolute pull range (APR) of ±50 ppm, corresponding to Option Code "E" in the ordering matrix. This setting determines the frequency deviation achievable via the VC pin (Pin 1) across its 0–VDD tuning range. The oscillator gain (KV) is calibrated accordingly - approximately 10–630 ppm/V depending on internal register settings - and is fixed at manufacture; no user adjustment is possible.
What is the significance of the "CDI" suffix in 8N4SV76FC-0096CDI?
The "CDI" suffix denotes three specific attributes: "C" indicates the CD package (6-lead ceramic 5 mm × 7 mm × 1.55 mm), "D" confirms lead-free (RoHS 6) construction, and "I" specifies industrial temperature range (–40°C to +85°C). This full suffix ensures mechanical, environmental, and regulatory compliance alignment - critical for deployment in base stations, optical line cards, and industrial Ethernet hardware where extended thermal operation is mandatory.
Can the 8N4SV76FC-0096CDI be used as a drop-in replacement for other IDT8N4SV76 variants?
No - the 8N4SV76FC-0096CDI is not pin-compatible or functionally interchangeable with other IDT8N4SV76 variants unless they share identical order-code structure (same supply voltage, stability option, package, and temperature grade). For example, a 3.3 V variant (e.g., 8N4SV76EC-XXXXCDI) uses different DC characteristics and may exceed voltage limits. Always verify supply voltage, pull range, and default frequency against the full part number before substitution.
