Product details

Overview

8N3SV75AC-0027CDI 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, ±20 ppm total stability (Option K), and 0.5 ps RMS phase jitter at 156.25 MHz (12 kHz–20 MHz). It operates from -40°C to +85°C and is used in wireless infrastructure baseband timing and high-speed SerDes clocking.

For engineers reviewing the 8N3SV75AC-0027CDI datasheet, 8N3SV75AC-0027CDI pinout, 8N3SV75AC-0027CDI application, or 8N3SV75AC-0027CDI equivalent, key selection criteria include its programmable APR (±4.5 to ±754.5 ppm), OE-controlled LVPECL differential outputs, dual supply compatibility (2.5 V/3.3 V), and ceramic 5 mm × 7 mm × 1.55 mm package with thermal resistance of 49.4°C/W.

Technical Context

The 8N3SV75AC-0027CDI integrates a 114.285 MHz third-overtone crystal oscillator, fractional-N PLL with delta-sigma modulator, and configurable pre-divider (P), feedback divider (MINT/MFRAC), and post-divider (N) to synthesize precise output frequencies. Its architecture enables 218 Hz frequency resolution and low-noise multiplication via high-reference-frequency operation.

Control is implemented through analog VC input (0–VCC, 10%–90% tuning range) and digital OE input (LVCMOS/LVTTL compatible), enabling dynamic output enable/disable and voltage-tuned frequency pulling. The device uses internal ROM for factory-stored configuration including frequency, pull range, and control polarity.

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; ±50 ppm stability (standard grade); 0.7 ps jitter @ 156.25 MHz.	Limited to LVDS-receiving PHYs; lacks OE control; lower stability unsuitable for holdover-critical SyncE.	Select only if LVDS interface and commercial temperature range suffice; verify APR coverage matches system pull budget.
AK210-0017	3.3 V only; ±25 ppm stability; 0.65 ps jitter; 7 mm × 5 mm package; no OE pin.	No output enable function; larger footprint; higher jitter margin may impact 100G+ SerDes BER.	Consider for cost-sensitive non-holdover applications where OE gating is unnecessary and board area permits larger package.

Compared with Si510-PROG and AK210-0017, the 8N3SV75AC-0027CDI uniquely combines LVPECL outputs, OE control, ±20 ppm stability, and 0.5 ps jitter in a compact 5 mm × 7 mm ceramic package-making it optimal for space-constrained, high-reliability wireless and optical infrastructure designs.

FAQ

What is the factory-programmed output frequency of the 8N3SV75AC-0027CDI?

The 8N3SV75AC-0027CDI is factory-programmed to a specific default frequency defined by its order code suffix "0027"; per IDT's FemtoClock NG ordering documentation, "0027" corresponds to 156.25 MHz - a standard frequency for Ethernet PHYs and SyncE applications. This frequency is permanently stored in on-chip ROM and cannot be altered in the field.

Does the 8N3SV75AC-0027CDI support both 2.5 V and 3.3 V supply voltages simultaneously?

No, the 8N3SV75AC-0027CDI operates from a single supply: either 2.5 V ±5% or 3.3 V ±5%, as determined by its Option Code "K" (3.3 V, ±20 ppm). It does not support dual-supply operation. The supply voltage must be stable and well-decoupled; mixing supplies or applying both voltages will damage the device.

How is the absolute pull range (APR) configured for the 8N3SV75AC-0027CDI?

The APR for the 8N3SV75AC-0027CDI is factory-programmed and fixed per order code; "0027" maps to an APR of ±100 ppm (typical). This value is stored in internal configuration registers and cannot be modified after shipment. APR defines the maximum frequency deviation achievable via the VC pin under specified control voltage range (0–VCC).

Can the 8N3SV75AC-0027CDI be used in place of a fixed-frequency XO?

Yes - when operated with a fixed VC voltage (e.g., VCC/2), the 8N3SV75AC-0027CDI functions as a highly stable, low-jitter XO. Its ±20 ppm total stability (Option K) and 0.5 ps jitter meet or exceed many standalone XOs. However, unlike a pure XO, it retains full VCXO functionality if system-level tuning is later required.

What termination is required for the LVPECL outputs of the 8N3SV75AC-0027CDI?

The 8N3SV75AC-0027CDI LVPECL outputs (Q/nQ) require 50 Ω differential termination to VCC – 2 V. For 3.3 V operation, this is 1.3 V; for 2.5 V, it approximates ground. Recommended layouts include Figure 1A/B (3.3 V) or Figure 2C (2.5 V) from the datasheet. AC-coupling and matched trace lengths are mandatory for signal integrity above 500 MHz.
