Product details
Overview
8N4SV75KC-0076CDI from Renesas Electronics (formerly IDT) is a factory-programmed LVDS voltage-controlled crystal oscillator (VCXO) with fourth-generation FemtoClock® NG PLL synthesis, supporting output frequencies from 15.476 MHz to 866.67 MHz and 975 MHz to 1,300 MHz, ±20 ppm total stability over -40°C to +85°C, and 0.53 ps RMS phase jitter at 156.25 MHz (12 kHz–20 MHz). It serves as a low-jitter, frequency-flexible timing source in wireless infrastructure baseband units.
For engineers reviewing the 8N4SV75KC-0076CDI datasheet, 8N4SV75KC-0076CDI pinout, 8N4SV75KC-0076CDI application, or 8N4SV75KC-0076CDI equivalent, this page delivers verified technical context, exact pin roles, real-world application mappings, and validated alternative options for telecom clocking systems requiring stable, programmable VCXOs with LVDS outputs and industrial temperature operation.
Technical Context
The 8N4SV75KC-0076CDI integrates a 114.285 MHz third-overtone crystal oscillator with a fractional-N PLL featuring a 7-bit integer plus 18-bit fractional feedback divider (MINT/MFRAC), 2-bit pre-divider (P), and 7-bit post-divider (N), enabling sub-218 Hz frequency resolution. Its FemtoClock® NG VCO operates at 1950–2600 MHz before division.
It implements LVDS differential output (Q/nQ), LVCMOS/LVTTL-compatible output enable (OE), and analog VCXO control voltage (VC) input with programmable polarity and absolute pull-range (APR) from ±4.5 to ±754.5 ppm. The device uses internal ROM configuration registers to store factory-set frequency, APR, and control polarity - no external programming required after shipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | LVDS differential pair (Q/nQ) - compatible with standard 100 Ω point-to-point termination and immune to common-mode noise. |
| Frequency Range | 15.476–866.67 MHz and 975–1300 MHz - covers Ethernet, CPRI, OTN, and wireless fronthaul clocking bands. |
| RMS Phase Jitter | 0.53 ps typical at 156.25 MHz (12 kHz–20 MHz integration) - meets stringent SONET/SDH OC-192 and 10G Ethernet jitter budgets. |
| Supply Voltage | 2.5 V or 3.3 V ±5% - dual-voltage support simplifies integration into mixed-supply telecom platforms. |
| Operating Temp | -40°C to +85°C - qualified for industrial ambient conditions in outdoor macrocell and small-cell base stations. |
| Total Stability | ±33 ppm (Option K) - includes initial accuracy, temperature drift, and 10-year aging; enables precise synchronization without recalibration. |
| Control Interface | Single VC input (0–VDD) with programmable polarity and oscillator gain from 7.57 to 477.27 ppm/V - supports custom loop filter design for PLL applications. |
Pinout & Package
6-lead ceramic package (5 mm × 7 mm × 1.55 mm, RoHS 6-compliant CD package); surface-mount, lead-free, industrial-grade thermal performance (θJA = 49.4°C/W, no airflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VC | VCXO control voltage input | Analog tuning input (0–VDD); sets output frequency deviation per programmed APR and polarity; internal 500 kΩ impedance. |
| 2 - OE | Output enable (active-high) | LVCMOS/LVTTL-compatible; drives Q/nQ into high-impedance state when low; default logic high enables output. |
| 3 - GND | Power supply ground | Dedicated ground reference for analog and digital sections; must be low-inductance connection to minimize jitter. |
| 4 - Q | LVDS positive clock output | Differential LVDS output (247–454 mV swing); requires 100 Ω termination to VDD/2 or AC-coupled receiver. |
| 5 - nQ | LVDS negative clock output | Complementary LVDS output; paired with Q for noise rejection; matched delay critical for skew-sensitive interfaces. |
| 6 - VDD | Power supply input | 2.5 V or 3.3 V ±5%; requires local 0.1 µF ceramic decoupling adjacent to pin to suppress supply-induced jitter. |
Key Features
| Feature | Design Value |
|---|---|
| FemtoClock® NG PLL architecture | Enables ultra-low phase noise via high 114.285 MHz reference and delta-sigma fractional-N synthesis - reduces multiplication-induced jitter. |
| Factory-programmed frequency & APR | Eliminates field programming; guarantees 218 Hz resolution and ±20 ppm stability (Option K) out-of-box for production deployment. |
| LVDS output with OE control | Supports hot-plug and power-aware system states; OE pin allows dynamic clock gating without disrupting upstream PLLs. |

| CPRI/Ethernet Fronthaul Gateways | High-Speed Data Acquisition Systems |
Use Scenario: Providing deterministic clocking for CPRI interface chips linking remote radio heads (RRH) to centralized baseband units (BBUs). IC Role / Device Role / Timing Role: VCXO referenced by slave-side PLLs to align with master clock over fiber; VC input enables fine-grained frequency alignment.

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-based XO (not VCXO); no analog VC input; fixed ±50 ppm stability; 10–945 MHz range. | Lacks voltage-controlled tuning; unsuitable for PLL lock-loop or dynamic frequency adjustment use cases. | Select only if application requires one-time programmability and no analog control loop. |
| AK210-01-0001 | LVDS VCXO with ±100 ppm stability; 10–800 MHz range; 0.8 ps RMS jitter at 156.25 MHz; -40°C to +85°C. | Higher jitter and looser stability limit it to non-Stratum 3E applications like enterprise switches or test fixtures. | Acceptable for cost-sensitive designs where ±100 ppm and 0.8 ps jitter meet system-level sync margin. |
Compared with 8N4SV75KC-0076CDI, Si510-PROG offers field reprogrammability but no VCXO functionality, while AK210-01-0001 provides lower-cost VCXO operation at reduced stability and jitter performance - making 8N4SV75KC-0076CDI the optimal choice for telecom infrastructure demanding Stratum 3E compliance and sub-0.55 ps jitter.

FAQ
What is the factory-programmed frequency and pull range of the 8N4SV75KC-0076CDI?
The 8N4SV75KC-0076CDI is factory-programmed to a specific frequency and absolute pull-range (APR) defined by its order code suffix "0076". Per IDT's ordering documentation, "0076" corresponds to a default frequency configuration and APR setting - not publicly disclosed in the datasheet but guaranteed per unit shipment. The device cannot be reprogrammed in the field; all timing parameters are fixed at manufacture.
Does the 8N4SV75KC-0076CDI support dual-frequency selection via FSEL?
No. The 8N4SV75KC-0076CDI uses the "V76" variant code, indicating a single-frequency VCXO with output enable active-high on pin 2 (OE@2). Dual-frequency selection via FSEL is supported only on "V75" and "V01" variants. The 8N4SV75KC-0076CDI contains one factory-configured frequency in its ROM and lacks an FSEL pin.
What is the maximum allowable control voltage (VC) range for the 8N4SV75KC-0076CDI?
The 8N4SV75KC-0076CDI accepts VC input from 0 V to VDD (either 2.5 V or 3.3 V), per Table 5B in the datasheet. Operation outside this range - including negative voltages or exceeding VDD + 0.5 V - violates Absolute Maximum Ratings and may cause permanent damage. The nominal tuning point is VC = VDD/2.
Can the 8N4SV75KC-0076CDI operate with a 2.5 V supply and still meet its jitter specification?
Yes. The 8N4SV75KC-0076CDI is fully characterized at both 2.5 V and 3.3 V supplies. Its RMS phase jitter remains within spec - e.g., 0.48–1.4 ps (15–100 MHz), 0.46–0.67 ps (500–1300 MHz) - across the full -40°C to +85°C range under either supply, as confirmed in Tables 4B and 5A of the datasheet.
Is the 8N4SV75KC-0076CDI pin-compatible with other IDT8N4SV75 variants?
Yes - all IDT8N4SV75x variants (including 8N4SV75KC-0076CDI) share identical 6-pin CD package pinout (VC/OE/GND/Q/nQ/VDD), mechanical dimensions (5 mm × 7 mm × 1.55 mm), and thermal characteristics. However, functional differences exist: OE polarity (active-high vs. active-low), FSEL presence, and factory-programmed parameters vary by suffix - verify logic behavior before substitution.
