Product details
Overview
8N3SV75AC-0029CDI8 from Renesas Electronics is a factory-programmed LVPECL voltage-controlled crystal oscillator (VCXO) with fourth-generation FemtoClock® NG PLL synthesis, delivering 15.476–866.67 MHz or 975–1300 MHz output frequencies at ≤218 Hz resolution, ±50 ppm total stability over 10 years, and 0.5 ps RMS phase jitter (12 kHz–20 MHz) at 156.25 MHz - used in wireless infrastructure baseband timing and telecom line-card clocking.
For engineers reviewing the 8N3SV75AC-0029CDI8 datasheet, 8N3SV75AC-0029CDI8 pinout, 8N3SV75AC-0029CDI8 application, or 8N3SV75AC-0029CDI8 equivalent, this page provides verified package mapping (6-lead ceramic 5×7 mm), confirmed LVPECL differential output architecture, factory-set VCXO pull range and control polarity, absolute pull range of ±4.5 to ±754.5 ppm, and OE-enabled high-impedance state control per JEDEC J65.
Technical Context
The 8N3SV75AC-0029CDI8 integrates a 114.285 MHz 3rd-overtone crystal oscillator driving a fractional-N PLL with 7-bit integer (MINT) and 18-bit fractional (MFRAC) feedback dividers, 2-bit pre-divider (P), and 7-bit post-divider (N), enabling ultra-fine frequency synthesis across two disjoint bands. Its VCO operates at 1950–2600 MHz before division.
Control is implemented via analog VC input (0–VCC, 10%–90% tuning range) with programmable oscillator gain (7.57–477.27 ppm/V at 3.3 V), and digital OE input (LVCMOS/LVTTL compatible) that places Q/nQ outputs into high-impedance state when low. Internal ROM stores factory-configured frequency, APR, and VC polarity.

Pinout & Package
6-lead ceramic VFQFN (5 mm × 7 mm × 1.55 mm), lead-free (RoHS 6), top-view pin assignment per IDT8N3SV75CCD Rev A: Pin 1 = VC, Pin 2 = OE, Pin 3 = VEE, Pins 4–5 = nQ/Q (differential LVPECL outputs), Pin 6 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VC | VCXO control voltage input | Analog tuning port; 0–VCC range sets output frequency deviation; internal ZVC = 500 kΩ 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 only; no LVPECL option; 10–945 MHz range; 1.2 ps phase jitter (156.25 MHz) | Lacks native LVPECL drive strength and noise immunity for long-backplane traces | Select if LVDS interface and lower cost outweigh jitter and voltage interface trade-offs |
| AK210-012500 | Fixed 125 MHz output; no frequency programming; ±20 ppm stability; 0.35 ps jitter | Not programmable; limited to single-frequency deployments requiring minimal holdover margin | Choose only for static clock trees where field reconfiguration is unnecessary |
Compared with Si510-PROG and AK210-012500, the 8N3SV75AC-0029CDI8 uniquely combines factory-programmable LVPECL output, dual-band frequency coverage, sub-0.5 ps jitter, and ±50 ppm 10-year stability - making it the sole option for carrier-class programmable timing in thermally demanding, high-speed serial interfaces.

FAQ
What output frequency is programmed into the 8N3SV75AC-0029CDI8?
The 8N3SV75AC-0029CDI8 is factory-programmed to 156.25 MHz - a standard Ethernet and OTN reference frequency - with 218 Hz resolution and guaranteed ±50 ppm total stability over 10 years. This value is permanently stored in on-chip ROM and cannot be altered in-system.
Does the 8N3SV75AC-0029CDI8 support both 2.5 V and 3.3 V supply voltages?
No, the 8N3SV75AC-0029CDI8 is configured for 3.3 V ±5% operation only (Option Code E). It draws 130–160 mA and is not rated for 2.5 V supply; applying 2.5 V will result in undefined behavior and failure to meet AC specifications including phase jitter and startup time.
What is the absolute pull range (APR) of the 8N3SV75AC-0029CDI8?
The 8N3SV75AC-0029CDI8 has a factory-programmed absolute pull range of ±200 ppm, enabling precise frequency alignment during network synchronization events. This APR is fixed at manufacturing and corresponds to an oscillator gain of 477.27 ppm/V at 3.3 V supply, with VC input ranging from 0.33 V to 2.97 V.
How does the OE pin function on the 8N3SV75AC-0029CDI8?
The OE pin (Pin 2) is an LVCMOS/LVTTL-compatible active-high control input with internal 50 kΩ pullup. When driven low, it places both Q and nQ LVPECL outputs into high-impedance state - essential for hot-swap, power gating, and redundancy switching. Startup defaults to enabled (OE = high) after power-on reset.
Can the 8N3SV75AC-0029CDI8 be used in place of a fixed-frequency XO?
Yes, the 8N3SV75AC-0029CDI8 can replace fixed XOs when its factory-programmed frequency matches the target (e.g., 156.25 MHz), but it adds VCXO functionality: tunability over ±200 ppm and OE control. Unlike XOs, it requires VC biasing and supports dynamic frequency adjustment - making it suitable for applications needing holdover or synchronization agility.
