Product details
Overview
8N4SV75KC-0076CDI8 from Renesas Electronics (formerly IDT) is a factory-programmed LVDS voltage-controlled crystal oscillator (VCXO) with fourth-generation FemtoClock® NG PLL synthesis. It delivers programmable 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, 0.53 ps RMS phase jitter at 156.25 MHz (12 kHz–20 MHz), and operates from 2.5 V or 3.3 V supply. It serves as a low-jitter timing source in wireless baseband units and high-speed SerDes clocking.
For engineers reviewing the 8N4SV75KC-0076CDI8 datasheet, 8N4SV75KC-0076CDI8 pinout, 8N4SV75KC-0076CDI8 application, or 8N4SV75KC-0076CDI8 equivalent, key selection criteria include its dual-band frequency coverage, factory-set ±20 ppm stability (Option K), LVDS differential output compliance, OE-enabled output control, and ceramic 5 mm × 7 mm × 1.55 mm CD package suitability for space-constrained telecom modules.
Technical Context
The 8N4SV75KC-0076CDI8 integrates a 114.285 MHz 3rd-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). Its FemtoClock® NG VCO operates at 1950–2600 MHz, enabling high-resolution synthesis with ≤218 Hz frequency step size.
It supports factory-configured VCXO pull range (±4.5 to ±754.5 ppm) and control voltage polarity, with oscillator gain tunable from 7.57 to 477.27 ppm/V (at 3.3 V) and modulation bandwidth of 100 kHz. The device uses delta-sigma noise shaping to minimize phase noise, achieving –113 dBc/Hz at 10 kHz offset from 156.25 MHz carrier.

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 LVDS; 10–210 MHz range; ±50 ppm stability (industrial) | Limited to lower-frequency control-plane clocks; unsuitable for high-speed SerDes | Select only if LVDS is not required and frequency stays below 210 MHz |
| AK2-156.250MHZ-E | Fixed-frequency LVDS XO (no VCXO function); ±25 ppm stability; same CD package | No voltage tuning capability; cannot compensate for system-level drift or PTP servo adjustments | Choose when absolute frequency stability suffices and no dynamic pull-range is needed |
Compared with 8N4SV75KC-0076CDI8, Si510-PROG lacks LVDS drive and high-frequency coverage, while AK2-156.250MHZ-E omits VCXO functionality entirely-making 8N4SV75KC-0076CDI8 the sole option for programmable, LVDS-based, ±20 ppm-stable VCXO operation above 150 MHz in telecom infrastructure.

FAQ
What is the factory-programmed frequency and pull range for 8N4SV75KC-0076CDI8?
The 8N4SV75KC-0076CDI8 is programmed with Option K (±20 ppm total stability) and default configuration code "0076", indicating a specific factory-set frequency and absolute pull range (APR) within the supported bands (15.476–866.67 MHz or 975–1300 MHz). Exact values are defined in the ordering documentation and must be confirmed via Renesas' FemtoClock NG Programming Guide or order-specific configuration report. The 8N4SV75KC-0076CDI8 does not support field reprogramming.
Does 8N4SV75KC-0076CDI8 support both 2.5 V and 3.3 V supply voltages simultaneously?
No. The 8N4SV75KC-0076CDI8 operates from either 2.5 V ±5% or 3.3 V ±5%, but not both concurrently. The supply voltage is selected at factory programming and fixed for the life of the device. The 8N4SV75KC-0076CDI8 datasheet specifies separate DC characteristics tables for each voltage; users must verify VDD rating on the device marking and match it to their board's power rail. Incorrect voltage may cause functional failure or accelerated aging.
How is the output enable (OE) pin configured on 8N4SV75KC-0076CDI8?
On the 8N4SV75KC-0076CDI8, OE is an LVCMOS/LVTTL-compatible input on pin 2 with internal pull-up resistor (~50 kΩ). When OE = high (≥2.0 V at 3.3 V supply), Q/nQ outputs are active; when OE = low (≤0.8 V), outputs enter high-impedance state. The 8N4SV75KC-0076CDI8 does not support inverted OE logic-the "V76" suffix denotes standard active-high OE, unlike "V75" which uses active-low OE.
Can 8N4SV75KC-0076CDI8 be used as a drop-in replacement for 8N4SV75EC-0076CDI8?
No. While both share the same package and pinout, 8N4SV75KC-0076CDI8 (Option K, ±20 ppm) and 8N4SV75EC-0076CDI8 (Option E, ±50 ppm) differ in factory-programmed frequency stability, oscillator gain, and thermal drift behavior. Substituting them without redesign risks violating system-level jitter or wander specifications. The 8N4SV75KC-0076CDI8 must be validated independently in the target application, especially for Stratum-3E or IEEE 1588 use cases.
What is the recommended termination for the LVDS outputs of 8N4SV75KC-0076CDI8?
The 8N4SV75KC-0076CDI8 LVDS outputs (Q/nQ) require a 100 Ω differential termination resistor placed as close as possible to the receiver input. This matches the typical PCB differential impedance and minimizes reflections. Per Renesas' Application Information, a point-to-point topology with 100 Ω parallel termination is standard; optional center-tap capacitance (≈50 pF) may be added to suppress common-mode noise. The 8N4SV75KC-0076CDI8 output driver is designed for this load and will not meet jitter specs with unterminated or mismatched traces.
