Product details
Overview
8N3SV75BC-0094CDI 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, ±50 ppm temperature stability, and 0.44–1.2 ps RMS phase jitter (12 kHz–20 MHz), deployed in wireless infrastructure baseband timing and telecom line-card clocking.
For engineers reviewing the 8N3SV75BC-0094CDI datasheet, 8N3SV75BC-0094CDI pinout, 8N3SV75BC-0094CDI application, or 8N3SV75BC-0094CDI equivalent, key selection criteria include its dual-band frequency coverage, factory-set ±50 ppm APR, LVPECL differential output compliance, OE-controlled high-impedance state, and ceramic 5 mm × 7 mm CD package suitability for high-density RF and networking PCBs.
Technical Context
The 8N3SV75BC-0094CDI integrates a 114.285 MHz 3rd-overtone crystal oscillator driving a fractional-N PLL with pre-divider (P), integer+fractional feedback divider (MINT/MFRAC), and post-divider (N), enabling precise frequency synthesis across two disjoint bands. Its VCO operates at 1950–2600 MHz before division.
Control is implemented via analog VC input (0–VCC, 7.57–477.27 ppm/V gain) and digital OE input (LVCMOS/LVTTL compatible), with internal pullup resistors on OE and configurable control voltage polarity. The device uses delta-sigma modulation for noise shaping and achieves low phase noise through high reference frequency and optimized loop filtering.

|---|---|
Use Scenario: Providing synchronized sampling clocks for multi-carrier LTE/5G massive MIMO RF front-ends operating at 1228.8 MHz and 2457.6 MHz. IC Role / Device Role / Timing Role: Primary VCXO source for ADC/DAC sampling clocks and FPGA fabric timing, locked to external 10 MHz reference via VC input. Use Value: Sub-0.5 ps RMS jitter ensures <0.1 dB EVM degradation at 256-QAM; ±50 ppm stability maintains holdover accuracy during GPS outage. | Use Scenario: Generating SONET/SDH and OTU4 line-rate clocks (e.g., 9.953 Gbps) in DWDM terminal multiplexers with hitless switching. IC Role / Device Role / Timing Role: Low-jitter VCXO feeding a clock cleaner IC (e.g., IDT8T49N242) to meet ITU-T G.8262 EEC-2 mask requirements. Use Value: 0.44 ps jitter at 1 GHz+ enables >30 dB phase margin in PLL-based clock regeneration; industrial temp rating supports uncooled chassis deployment. |
| Enterprise Switch Fabric Timing | High-Frequency Trading (HFT) Data Acquisition |
Use Scenario: Delivering deterministic 156.25 MHz and 312.5 MHz clocks to 10G/25G/100G switch ASICs and SerDes PHYs in modular chassis. IC Role / Device Role / Timing Role: System master clock generator with OE-controlled shutdown during link training or firmware update. Use Value: 10 ms startup time aligns with PCIe Gen4/Gen5 reset timing; LVPECL drive strength supports fanout to ≥4 loads without repeaters. | Use Scenario: Synchronizing ultra-low-latency FPGA-based packet timestamping and market data feed processing at sub-10 ns precision. IC Role / Device Role / Timing Role: Reference oscillator for high-resolution TDCs and time-stamping units requiring minimal jitter-induced timestamp uncertainty. Use Value: 0.5 ps RMS jitter (156.25 MHz) translates to <1.5 ps timestamp error floor; ceramic package ensures mechanical stability under vibration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-PROG | CMOS output only; programmable via I²C; no LVPECL option; ±20 ppm stability (K-grade) | Requires external level-shifter for LVPECL interfaces; better suited for microcontroller-based control loops | Select if digital reconfiguration and lower power (<50 mA) outweigh need for native LVPECL drive |
| AK2-156.250MHZ-E | Fixed-frequency LVPECL XO (no VC input); ±25 ppm stability; 0.6 ps jitter @ 156.25 MHz | Lacks pull-range tuning; used where external PLL handles frequency agility | Select for cost-sensitive, static-clock applications where VCXO flexibility is unnecessary |
Compared with Si510-PROG and AK2-156.250MHZ-E, the 8N3SV75BC-0094CDI uniquely delivers factory-programmed LVPECL VCXO performance in a single 6-pin ceramic package with guaranteed ±50 ppm stability and sub-0.5 ps jitter above 500 MHz-critical for next-gen wireless and optical systems requiring both precision and tunability.

FAQ
What is the factory-programmed output frequency of the 8N3SV75BC-0094CDI?
The 8N3SV75BC-0094CDI is programmed to a specific default frequency at manufacture; the "0094" suffix in the part number corresponds to a factory-set frequency per Renesas' FemtoClock NG ordering matrix. Exact value requires cross-referencing with the official "FemtoClock NG Ceramic-Package XO and VCXO Ordering Product Information" document or contacting Renesas directly-Aetrix can provide traceable configuration records upon request.
Does the 8N3SV75BC-0094CDI support 2.5 V operation?
No, the 8N3SV75BC-0094CDI does not support 2.5 V operation. Its Option Code "B" denotes 2.5 V ±5%, but the "E" in "8N3SV75BC-0094CDI" explicitly indicates 3.3 V ±5% supply voltage per Renesas' ordering nomenclature. Attempting 2.5 V operation will result in undefined behavior and failure to meet AC specifications.
Can the 8N3SV75BC-0094CDI be reprogrammed in-system?
No, the 8N3SV75BC-0094CDI is factory-programmed with immutable configuration stored in ROM-including frequency, APR, and VC polarity. It lacks serial interface pins or flash memory; reprogramming requires replacement with a newly configured unit. Field tuning is limited to analog VC voltage adjustment within the programmed APR.
What is the recommended termination for the LVPECL outputs of the 8N3SV75BC-0094CDI?
For 3.3 V operation, terminate each LVPECL output (Q and nQ) with a 50 Ω resistor to VCC – 2 V (1.3 V), using either discrete resistors or integrated termination networks. Renesas provides two validated topologies in the datasheet (Figures 1A and 1B); mismatched termination causes signal integrity degradation, increased jitter, and duty cycle distortion beyond 45–55% spec.
Is the 8N3SV75BC-0094CDI pin-compatible with other IDT8N3SV75 variants?
Yes, all IDT8N3SV75 VCXOs-including the 8N3SV75BC-0094CDI-share identical 6-pin CD package footprint and pinout (VC/OE/VEE/Q/nQ/VCC). However, electrical differences (supply voltage, stability grade, pull range) mean direct substitution may violate system specs unless verified against the target variant's datasheet section "Table 5A" and "Table 5B".
