Product details
Overview
8N3SV75KC-0058CDI from Renesas Electronics is a factory-programmed LVPECL voltage-controlled crystal oscillator (VCXO) with fourth-generation FemtoClock® NG PLL synthesis, supporting 15.476–866.67 MHz and 975–1300 MHz output frequencies at ≤218 Hz resolution, ±20 ppm total stability over 10 years, and RMS phase jitter of 0.44 ps (500–1300 MHz), deployed in wireless infrastructure baseband timing and telecom line-card clocking.
For engineers reviewing the 8N3SV75KC-0058CDI datasheet, 8N3SV75KC-0058CDI pinout, 8N3SV75KC-0058CDI application, or 8N3SV75KC-0058CDI equivalent, key selection criteria include guaranteed ±20 ppm total stability (Option K), 3.3V LVPECL output compliance, -40°C to 85°C industrial operation, and factory-configured VCXO pull range and control polarity for deterministic tuning behavior.
Technical Context
The 8N3SV75KC-0058CDI integrates a 114.285 MHz third-overtone crystal oscillator with a fractional-N PLL featuring a 7-bit integer + 18-bit fractional feedback divider (MINT/MFRAC), 2-bit pre-divider (P), and 7-bit post-divider (N), enabling high-resolution frequency synthesis across two disjoint bands. Its FemtoClock® NG VCO operates at 1950–2600 MHz before division.
Control is implemented via a single analog VC input (0–VCC, 10%–90% tuning range) with programmable oscillator gain (7.57–477.27 ppm/V at 3.3V) and linearity (±0.1% BSL), plus an LVCMOS/LVTTL-compatible OE pin that places Q/nQ outputs in high-impedance state when low. Power is supplied at 3.3V ±5% only (Option K).

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 8N3SV75EC-0058CDI | Same package and pinout; Option E (±50 ppm total stability, 3.3V) instead of Option K (±20 ppm). | Suitable for enterprise networking gear where tighter stability is not mandated by standards. | Select when ±50 ppm meets system-level timing budget and cost optimization is prioritized over telecom-grade stability. |
| Si510-PROG | Programmable I²C-configurable XO/VCXO; 10–945 MHz range; typical 0.5 ps jitter; 5×7 mm QFN; no OE pin. | Requires firmware initialization; lacks hardware OE control and guaranteed APR programming. | Choose when field reprogramming is needed and system MCU can manage I²C configuration during boot. |

FAQ
What is the factory-programmed frequency and pull range for 8N3SV75KC-0058CDI?
The 8N3SV75KC-0058CDI is programmed to a specific default frequency and absolute pull range (APR) at manufacture; the "0058" order code corresponds to a unique configuration documented in Renesas' FemtoClock NG Ceramic-Package XO and VCXO Ordering Product Information. The APR is set to a typical value between ±4.5 ppm and ±754.5 ppm, and the control voltage polarity is fixed per factory setting. Full details require referencing the official Renesas order code guide-not the generic datasheet.
Does 8N3SV75KC-0058CDI support 2.5V supply operation?
No, 8N3SV75KC-0058CDI does not support 2.5V supply operation. The "K" option code explicitly specifies 3.3V ±5% supply voltage (per Table 8 in the datasheet). Using 2.5V will result in undefined behavior, failure to start, or violation of AC/DC specifications. For 2.5V operation, select an "F" or "B" option variant such as 8N3SV75FC-0058CDI.
What is the recommended termination for the LVPECL outputs of 8N3SV75KC-0058CDI?
For 3.3V LVPECL operation, terminate each output (Q and nQ) with a 50 Ω resistor to VCC – 2 V (i.e., 1.3 V), as shown in Figure 1A/B of the datasheet. This matches the LVPECL driver's output impedance and ensures optimal signal integrity, duty cycle, and jitter performance. Avoid unterminated or AC-coupled-only configurations, which degrade edge rates and increase deterministic jitter.
Can the 8N3SV75KC-0058CDI be reprogrammed after shipment?
No, the 8N3SV75KC-0058CDI is factory-programmed with permanent ROM configuration (frequency, APR, polarity) and cannot be reprogrammed in the field. It lacks I²C, SPI, or other configuration interfaces. Reprogramming requires wafer-level customization prior to packaging. For field-programmable alternatives, consider the Si510 or Si534x families-but those differ in architecture, pinout, and jitter profile from the 8N3SV75KC-0058CDI.
What is the startup time and power-up sequencing requirement for 8N3SV75KC-0058CDI?
The 8N3SV75KC-0058CDI has a typical startup time of 10 ms after VCC reaches regulation (tSTARTUP, Table 5A). No strict power-up sequencing is required between VCC and VEE, but both must be stable before OE is asserted. OE should remain low until after startup completes to prevent metastable output states. Decoupling capacitors (0.1 µF ceramic per supply pin) must be placed adjacent to pins 3 (VEE) and 6 (VCC) to ensure clean power delivery and minimize jitter.
