Product details
Overview
8N3SV75KC-0067CDI from Renesas Electronics (formerly IDT) is a factory-programmed LVPECL voltage-controlled crystal oscillator (VCXO) with fourth-generation FemtoClock® NG PLL synthesis. It delivers 156.25 MHz output at ±20 ppm total stability over –40°C to +85°C, 0.5 ps RMS phase jitter (12 kHz–20 MHz), and operates from 2.5 V or 3.3 V supply. Used in telecom line cards and 10G/25G Ethernet PHY clocking.
For engineers reviewing the 8N3SV75KC-0067CDI datasheet, 8N3SV75KC-0067CDI pinout, 8N3SV75KC-0067CDI application, or 8N3SV75KC-0067CDI equivalent, key selection criteria include its programmable APR (±4.5 to ±754.5 ppm), LVPECL differential output compliance, OE-controlled high-impedance state, and ceramic 5 mm × 7 mm package with thermal resistance of 49.4°C/W.
Technical Context
The device integrates a 114.285 MHz third-overtone crystal oscillator and a fractional-N PLL with pre-divider (P), feedback divider (MINT + MFRAC), and post-divider (N). Its delta-sigma modulated feedback loop enables frequency resolution ≤218 Hz across two bands: 15.476–866.67 MHz and 975–1300 MHz.
Control is implemented via analog VC input (0–VCC, 7.57–477.27 ppm/V gain) and digital OE input (LVCMOS/LVTTL compatible), enabling precise tuning and output enable/disable without external logic. The internal ROM stores factory-configured frequency, pull range, and control polarity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 156.25 MHz - precisely programmed default frequency for Ethernet synchronization. |
| Frequency Stability | ±20 ppm (Option K) - guaranteed over –40°C to +85°C including aging and temperature drift. |
| RMS Phase Jitter | 0.5 ps (typical, 12 kHz–20 MHz) - meets stringent SONET/OTN and 10GBase-R jitter budgets. |
| Supply Voltage | 2.5 V or 3.3 V - dual-voltage support simplifies integration into mixed-supply systems. |
| Absolute Pull Range | Programmable ±4.5 to ±754.5 ppm - enables flexible loop bandwidth tuning in PLL-based clock recovery. |
| Output Interface | LVPECL differential (Q/nQ) - requires 50 Ω termination to VCC – 2 V; supports >866 MHz operation. |
| Startup Time | 10 ms - ensures deterministic initialization in hot-plug and reset-sensitive systems. |
Pinout & Package
6-lead ceramic VFQFN package (5 mm × 7 mm × 1.55 mm, RoHS 6-compliant); lead-free, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VC | VCXO control voltage input | Analog tuning port; 0–VCC range sets output frequency deviation per programmed KV gain. |
| 2 - OE | Output enable (LVCMOS/LVTTL) | Active-high; drives Q/nQ into high-Z when low - enables dynamic clock gating without external switches. |
| 3 - VEE | Negative power supply | Ground reference for LVPECL outputs; must be connected to system GND. |
| 4 - Q | Differential clock output (+) | LVPECL-compatible; 0.6–1.0 V peak-to-peak swing into 50 Ω to VCC – 2 V. |
| 5 - nQ | Differential clock output (–) | Complementary to Q; maintains <100 ps skew for low-jitter differential signaling. |
| 6 - VCC | Positive power supply | Accepts 2.5 V ±5% or 3.3 V ±5%; decoupling required within 2 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| FemtoClock® NG PLL architecture | Delta-sigma fractional-N synthesis enables 218 Hz frequency resolution and ultra-low phase noise. |

Applications
| 10G/25G Ethernet PHY Clocking | Synchronous Optical Networking (SONET/SDH) |
|---|---|

Use Value: Meets IEEE 802.3bj Annex 83F mask; eliminates need for external jitter cleaners in cost-sensitive optical modules. | Use Scenario: Generating STS-192/STM-64 line clocks in OC-192/STM-64 add-drop multiplexers. IC Role / Device Role / Timing Role: Stratum 3E-compliant VCXO for synchronous payload mapping and pointer justification. Use Value: ±20 ppm stability and 0.5 ps jitter ensure BER <10⁻¹² over temperature and aging; supports holdover during upstream sync loss. |
| Wireless Baseband Unit (BBU) | Packet Transport Network (PTN) Timing |
Use Scenario: Delivering phase-aligned clocks to FPGA-based digital front-end (DFE) and RFIC interfaces in 4G/5G macro cells. IC Role / Device Role / Timing Role: Programmable VCXO for adaptive clock recovery in CPRI/eCPRI fronthaul links.

IC Role / Device Role / Timing Role: High-stability oscillator for PTP grandmaster clock synchronization and time-of-day recovery. Use Value: Low aging (±3 ppm/10 yr) and tight initial accuracy (±10 ppm) reduce time error accumulation in multi-hop timing chains. |
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; no LVPECL; programmable in-system via I²C; ±50 ppm stability (min). | Requires external level-shifting for LVPECL loads; suited for FPGA clock inputs, not high-speed SERDES. | Select when field reprogrammability and multi-frequency agility outweigh fixed-output interface needs. |
| AK2-156.250MHZ-E | Fixed-frequency LVPECL XO (no VC input); ±20 ppm stability; same 5×7 mm ceramic package. | Lacks tuning capability; used where loop control is handled externally or not required. | Select when absolute frequency stability is prioritized over pull-range flexibility and VCXO functionality is unnecessary. |
Compared with 8N3SV75KC-0067CDI, Si510-PROG offers in-field frequency updates but sacrifices LVPECL drive strength and jitter performance, while AK2-156.250MHZ-E provides identical stability and form factor but removes VC tuning-making it suitable only for static clock trees.

FAQ
What is the factory-programmed output frequency of the 8N3SV75KC-0067CDI?
The 8N3SV75KC-0067CDI is factory-programmed to 156.25 MHz - a standard frequency for 10G Ethernet and OTN applications. This value is stored in on-chip ROM and cannot be altered post-manufacture. The device retains full VCXO functionality, allowing analog tuning around this center frequency within its configured absolute pull range.
Does the 8N3SV75KC-0067CDI support both 2.5 V and 3.3 V supply voltages?
Yes, the 8N3SV75KC-0067CDI supports either 2.5 V ±5% or 3.3 V ±5% VCC operation, as specified in Option Code K (3.3 V, ±20 ppm). LVPECL output levels and DC characteristics are characterized for both supplies. Power supply current is 130–160 mA at 3.3 V and 120–155 mA at 2.5 V, with identical jitter performance.
What is the meaning of "CDI" in the part number 8N3SV75KC-0067CDI?
In 8N3SV75KC-0067CDI, "CD" denotes the lead-free 6-lead ceramic 5 mm × 7 mm × 1.55 mm package, and "I" indicates industrial temperature range (–40°C to +85°C). The "K" specifies 3.3 V supply and ±20 ppm frequency stability. "0067" is the order-specific configuration code mapping to 156.25 MHz and its associated APR setting.
Can the 8N3SV75KC-0067CDI be used without connecting the VEE pin?
No - VEE must be connected to system ground. The 8N3SV75KC-0067CDI uses VEE as the reference for its LVPECL output stage; leaving it unconnected violates the absolute maximum rating and will cause output failure or excessive jitter. The datasheet explicitly defines VEE as the negative power supply terminal, not a floating node.
How does the OE pin function on the 8N3SV75KC-0067CDI?
The OE (Output Enable) pin on the 8N3SV75KC-0067CDI is an LVCMOS/LVTTL-compatible input that places the Q/nQ differential outputs into high-impedance state when driven low. When high (default), outputs are active. This enables clock domain isolation during power sequencing or fault conditions - critical for preventing bus contention in multi-clock systems.
