Product details
Overview
8N3SV75EC-0069CDI from Renesas Electronics (formerly IDT) is a factory-programmed LVPECL voltage-controlled crystal oscillator (VCXO) with programmable frequency and pull range, operating from 15.476 MHz to 866.67 MHz and 975 MHz to 1300 MHz, ±20 ppm temperature stability, and RMS phase jitter of 0.5 ps at 156.25 MHz (12 kHz–20 MHz). It serves as a low-jitter timing reference in wireless infrastructure baseband units.
For engineers reviewing the 8N3SV75EC-0069CDI datasheet, 8N3SV75EC-0069CDI pinout, 8N3SV75EC-0069CDI application, or 8N3SV75EC-0069CDI equivalent, key selection criteria include its fractional-N PLL architecture, 6-pin ceramic 5 mm × 7 mm package, LVPECL differential output compliance, OE-controlled high-impedance state, and factory-configured ±20 ppm APR for telecom-grade stability.
Technical Context
The 8N3SV75EC-0069CDI integrates a 114.285 MHz third-overtone crystal oscillator with a fourth-generation FemtoClock® NG fractional-N PLL, featuring a 2-bit pre-divider (P), 7-bit integer + 18-bit fractional feedback divider (MINT/MFRAC), and 7-bit post-divider (N). Its VCO operates at 1950–2600 MHz, enabling fine frequency resolution down to 218 Hz.
It supports dual supply options (2.5 V or 3.3 V), includes an LVCMOS/LVTTL-compatible output enable (OE) input, and delivers LVPECL outputs (Q/nQ) terminated into 50 Ω to VCC − 2 V. Control voltage (VC) linearity is ±0.1% BSL, with oscillator gain configurable from 7.57 to 477.27 ppm/V depending on supply voltage and programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | LVPECL differential clock output (Q/nQ), compatible with ECL/LVPECL receivers and requiring 50 Ω termination to VCC − 2 V. |

Pinout & Package
6-lead ceramic VFQFN package (5 mm × 7 mm × 1.55 mm, RoHS 6-compliant); lead-free, surface-mount, with exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VC | VCXO control voltage input | Analog tuning input (0–VCC); sets output frequency deviation within programmed APR; 500 kΩ input impedance. |

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, 3.3 V only, ±50 ppm stability (A grade), 10–945 MHz range, no OE pin | Lacks OE control and LVPECL drive; requires level-shifting for ECL interfaces | Select when LVDS interface suffices and ±50 ppm stability is acceptable for non-telecom use cases. |
| AK2-156.250MHZ-E | Fixed-frequency LVPECL XO (no VC tuning), ±20 ppm, same 5×7 mm package, no OE | No voltage control or frequency agility; lower cost but zero pull range | Select when static 156.25 MHz reference is sufficient and VCXO functionality is unnecessary. |
Compared with Si510-PROG and AK2-156.250MHZ-E, the 8N3SV75EC-0069CDI uniquely combines LVPECL output, hardware OE control, ±20 ppm stability, and factory-programmed VCXO tuning-making it the only option for telecom-grade, dynamically gated, frequency-agile clocking in constrained 5×7 mm footprints.

FAQ
What is the factory-programmed output frequency of the 8N3SV75EC-0069CDI?
The 8N3SV75EC-0069CDI is factory-programmed to 156.25 MHz, as indicated by the "0069" order code suffix in its part number. This frequency is optimized for Ethernet, CPRI, and OTU2/OTU4 applications. The device retains full VCXO functionality, allowing ±20 ppm tuning around 156.25 MHz via the VC pin. No reprogramming is possible after shipment-the configuration is permanently stored in ROM.
Does the 8N3SV75EC-0069CDI support both 2.5 V and 3.3 V supply voltages?
No-the 8N3SV75EC-0069CDI is configured for 3.3 V ±5% operation only, as specified by the "E" option code in its part number. Attempting to operate it at 2.5 V will result in undefined behavior and failure to meet AC specifications. The "B", "F", and "L" option codes denote 2.5 V variants; this part uses "E", confirming 3.3 V compatibility per Table 8 in the datasheet.
How is the output enable (OE) function implemented on the 8N3SV75EC-0069CDI?
The OE pin (Pin 2) is an LVCMOS/LVTTL-compatible active-high input with an internal 50 kΩ pullup resistor. When OE = 0 V (logic low), both Q and nQ outputs enter high-impedance state, effectively disconnecting the clock from downstream loads. When OE = VCC (logic high), outputs are enabled. This hardware gating eliminates software latency and supports hot-swap or power-domain sequencing in multi-clock systems.
What is the significance of the "CDI" suffix in 8N3SV75EC-0069CDI?
The "CDI" suffix denotes three key attributes: "C" = die revision C; "D" = 6-lead ceramic 5 mm × 7 mm × 1.55 mm RoHS 6-compliant package; "I" = industrial temperature range (−40°C to +85°C). This matches the CD package outline in Figure 1 and Table 7 of the datasheet, confirming mechanical and environmental compliance for harsh outdoor deployments.
Can the 8N3SV75EC-0069CDI be used as a drop-in replacement for fixed-frequency XO devices?
No-the 8N3SV75EC-0069CDI is a VCXO with intentional tuning capability and requires proper VC biasing and loop filter design for closed-loop applications. While it can operate as a fixed-frequency source when VC is held at VCC/2, its electrical characteristics (e.g., oscillator gain, linearity, bandwidth) differ from XOs. For true drop-in XO replacement, consider Renesas' fixed-frequency AK2 series or IDT8N3SV76 variants without VC pin.
