Product details
Overview
8N3SV75AC-0102CDI from Renesas Electronics (formerly IDT) is a factory-programmed LVPECL voltage-controlled crystal oscillator (VCXO) with fourth-generation FemtoClock® NG PLL synthesis, delivering programmable output frequencies from 15.476 MHz to 866.67 MHz and 975 MHz to 1,300 MHz at ≤218 Hz resolution, ±20 ppm total stability over 10 years, and 0.44 ps RMS phase jitter (500–1300 MHz band), used in wireless infrastructure baseband timing and high-speed SerDes clocking.
For engineers reviewing the 8N3SV75AC-0102CDI datasheet, 8N3SV75AC-0102CDI pinout, 8N3SV75AC-0102CDI application, or 8N3SV75AC-0102CDI equivalent, key selection criteria include its LVPECL differential output compliance, factory-set VCXO pull range and control polarity, -40°C to +85°C industrial temperature operation, and ceramic 5 mm × 7 mm × 1.55 mm CD package with OE-enabled output control.
Technical Context
The 8N3SV75AC-0102CDI integrates a 114.285 MHz third-overtone crystal oscillator driving a fractional-N PLL with pre-divider (P), integer+fractional feedback divider (MINT/MFRAC), and post-divider (N), enabling ultra-fine frequency synthesis across two disjoint bands. Its FemtoClock® NG VCO operates at 1950–2600 MHz before division.
Control is implemented via analog VC input (0–VCC, 500 kΩ impedance) and digital OE input (LVCMOS/LVTTL compatible), with internal pull-up on OE. Output enable places Q/nQ into high-impedance state; otherwise, outputs drive 50 Ω loads terminated to VCC – 2 V with 0.4–1.0 V peak-to-peak swing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | LVPECL differential pair (Q/nQ), compatible with ECL-terminated 50 Ω transmission lines |
| Frequency Range | 15.476–866.67 MHz and 975–1300 MHz; factory-programmed to exact target frequency |
| Frequency Resolution | ≤218 Hz - enables precise alignment to Ethernet, CPRI, OTU, and SerDes reference clocks |
| RMS Phase Jitter | 0.44 ps (typ.) @ 500–1300 MHz, 12 kHz–20 MHz integration - meets OC-192/STM-64 and 10G/25G Ethernet jitter budgets |
| Total Stability | ±33 ppm (10-year life, option K) - includes initial accuracy, temp drift, and aging; supports telecom-grade holdover |
| Supply Voltage | 3.3 V ±5% - powers core and outputs; supports legacy 3.3 V system rails without level translation |

Pinout & Package
6-lead ceramic VFQFN package (CD), 5 mm × 7 mm × 1.55 mm, RoHS 6-compliant, with exposed thermal pad (not electrically connected). Pin 1 marked by index dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VC) | VCXO tuning voltage input | Analog control port; 0–3.3 V range sets output frequency within factory-programmed APR (±20 ppm typical for K-option) |
| 2 (OE) | Output enable input | LVCMOS/LVTTL-compatible active-high signal; disables Q/nQ into high-Z when low |
| 3 (VEE) | Negative supply rail | Ground reference for LVPECL outputs; must be connected to system GND |
| 4 (Q) | Differential clock output (+) | LVPECL logic high = VCC – 0.8 V (min), low = VCC – 2.0 V (min); requires 50 Ω termination to VCC – 2 V |
| 5 (nQ) | Differential clock output (–) | Complementary to Q; defines differential swing and common-mode rejection for noise immunity |
| 6 (VCC) | Positive supply rail | 3.3 V ±5% main power; decoupling (0.1 µF near pin) required for sub-ps jitter performance |
Key Features
| Feature | Design Value |
|---|---|
| Fractional-N PLL with delta-sigma modulation | Enables 218 Hz frequency step size while suppressing quantization noise through shaped dithering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-PROG | LVDS output; 10–945 MHz range; ±50 ppm stability; 0.8 ps jitter @ 156.25 MHz | Lacks LVPECL interface; requires level-shifting for ECL-terminated systems | Choose when LVDS compatibility and broader low-frequency coverage outweigh jitter and interface trade-offs |

FAQ
What output frequency is factory-programmed in the 8N3SV75AC-0102CDI?
The 8N3SV75AC-0102CDI is factory-programmed to a specific frequency defined by its order code suffix "0102", which corresponds to a default frequency of 100.000 MHz per the IDT FemtoClock NG ordering documentation. This value is permanently stored in ROM and cannot be reprogrammed in-system.
Does the 8N3SV75AC-0102CDI support both 2.5 V and 3.3 V supply voltages?
No - the "A" in the order code 8N3SV75AC-0102CDI specifies Option Code A: VCC = 3.3 V ±5% and ±100 ppm frequency stability. It is not rated for 2.5 V operation; applying 2.5 V may result in undefined behavior or failure to meet AC specifications including jitter and startup time.
What is the absolute pull range (APR) of the 8N3SV75AC-0102CDI?
The 8N3SV75AC-0102CDI has a factory-programmed absolute pull range (APR) determined by its Option Code A configuration. While APR is programmable from ±4.5 to ±754.5 ppm, the actual APR for this part is ±100 ppm - matching its specified temperature stability grade and enabling precise loop bandwidth tuning in PLL applications.
How is the 8N3SV75AC-0102CDI terminated for optimal LVPECL signal integrity?
The 8N3SV75AC-0102CDI LVPECL outputs Q and nQ require DC-coupled 50 Ω termination to VCC – 2 V. For 3.3 V operation, this equals 1.3 V; recommended topologies include dual 84 Ω resistors (Figure 1A) or 125 Ω resistors (Figure 1B) referenced to 1.3 V. Improper termination causes duty cycle distortion and increased jitter in the 8N3SV75AC-0102CDI.
Is the 8N3SV75AC-0102CDI pin-compatible with other IDT8N3SV75 variants?
Yes - all IDT8N3SV75 VCXOs in the CD 6-lead ceramic package share identical pinout (VC/OE/VEE/Q/nQ/VCC), including the 8N3SV75AC-0102CDI. However, electrical behavior differs by option code (e.g., supply voltage, stability grade, default frequency), so substitution requires validation of APR, jitter, and thermal performance in the target application.
