Product details

Overview

8N3SV75LC-0018CDI8 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, ±4.5 to ±754.5 ppm absolute pull range, 0.5 ps RMS phase jitter at 156.25 MHz (12 kHz–20 MHz), and operation from –40°C to +85°C in telecom infrastructure timing applications.

For engineers reviewing the 8N3SV75LC-0018CDI8 datasheet, 8N3SV75LC-0018CDI8 pinout, 8N3SV75LC-0018CDI8 application, or 8N3SV75LC-0018CDI8 equivalent, key selection considerations include its LVPECL differential output compliance, factory-configured VCXO pull range and control polarity, dual-band frequency programmability, 218 Hz frequency resolution, and ceramic 5 mm × 7 mm × 1.55 mm CD package with OE-enabled output control.

Technical Context

The 8N3SV75LC-0018CDI8 integrates a 114.285 MHz third-overtone crystal reference with a fractional-N PLL featuring a 7-bit pre-divider (P), 7-bit integer + 18-bit fractional feedback divider (MINT/MFRAC), 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.

It implements delta-sigma noise shaping for low phase noise, supports LVCMOS/LVTTL-compatible OE input for output enable/disable, and uses internal pull-up resistors on OE and VC pins. The device accepts either 2.5 V or 3.3 V supply and delivers differential LVPECL outputs terminated into 50 Ω to VCC – 2 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Type	LVPECL differential clock output (Q/nQ), compatible with ECL/LVPECL transmission lines and requiring 50 Ω termination to VCC – 2 V.
Frequency Range	15.476–866.67 MHz and 975–1300 MHz - supports both Ethernet, CPRI, and OTN line rates without external dividers.
Frequency Resolution	218 Hz or better - enables precise alignment to standards like 156.25 MHz (10GBASE-R), 122.88 MHz (CPRI), or 125 MHz (SONET).

Pinout & Package

6-lead ceramic VFQFN package (CD), 5 mm × 7 mm × 1.55 mm, lead-free (RoHS 6), with exposed 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; internal 50 kΩ pull-up; 10%–90% VCC range.
2 - OE	Output enable input	LVCMOS/LVTTL-compatible active-high enable; pulls up internally; drives Q/nQ into high-impedance when low.
3 - VEE	Negative power supply	Ground reference for LVPECL outputs; must be connected to system ground (0 V) per datasheet configuration.
4 - Q	Differential clock output (+)	LVPECL logic-high = VCC – 0.8 V to VCC – 1.4 V; requires 50 Ω termination to VCC – 2 V for signal integrity.
5 - nQ	Differential clock output (–)	Complementary to Q; defines differential swing (0.4–1.0 Vpp); matched routing critical for skew control.
6 - VCC	Positive power supply	Supplies core and output drivers; decoupling with 0.1 µF capacitor required adjacent to pin for jitter optimization.

Key Features

Feature	Design Value
Fourth-gen FemtoClock® NG PLL	Enables sub-picosecond jitter via high-reference-frequency (114.285 MHz) fractional-N synthesis with delta-sigma noise shaping.
Factory-programmed APR & polarity	Eliminates field tuning complexity; pull range and VC polarity (positive/negative gain) are fixed at manufacture per order code.
2.5 V / 3.3 V dual-supply compatibility	Reduces need for level-shifting in mixed-voltage systems; IO thresholds auto-adapt to selected VCC.
OE-controlled high-impedance outputs	Allows dynamic clock gating in multi-source timing architectures without external switches or buffers.
Low RMS phase jitter (0.5 ps typ.)	Meets ITU-T G.823/G.824 wander and jitter masks for SDH/SONET and 10G/25G Ethernet physical layers.
Ceramic 5×7 mm CD package	Provides superior thermal stability vs. plastic packages; supports reflow soldering and long-term aging < ±5 ppm over 15 years.

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 LVPECL; uses DSPLL architecture; max 1024 MHz output; 1.2 ps jitter @ 156.25 MHz.	Requires external LVPECL translator for direct replacement; suited for lower-jitter budget systems where CMOS fanout suffices.	Select if board space allows discrete level-shifting and jitter spec permits >1 ps.
AK2-156.250MHZ-E	Fixed-frequency LVPECL XO (not VCXO); ±20 ppm stability; no VC or OE; 0.45 ps jitter @ 156.25 MHz.	Lacks frequency pulling capability; cannot support SyncE ESMC or IEEE 1588 phase adjustment; used only in free-running mode.	Select only when VCXO functionality is unnecessary and lowest possible jitter is mandatory.

Compared with Si510-PROG and AK2-156.250MHZ-E, the 8N3SV75LC-0018CDI8 uniquely combines factory-programmed LVPECL VCXO operation, dual-band frequency coverage, sub-0.5 ps jitter, and OE control in a single 6-pin ceramic package-making it optimal for telecom infrastructure requiring both precision and tunability.

FAQ

What output frequency is factory-programmed in the 8N3SV75LC-0018CDI8?

The 8N3SV75LC-0018CDI8 is factory-programmed to a default frequency of 156.25 MHz, as indicated by the "0018" suffix per IDT's ordering convention (where "0018" maps to 156.25 MHz in the FemtoClock NG Ceramic-Package XO and VCXO Ordering Product Information document). This frequency is commonly used for 10GBASE-R Ethernet and CPRI applications.

Does the 8N3SV75LC-0018CDI8 support both 2.5 V and 3.3 V supply voltages simultaneously?

No, the 8N3SV75LC-0018CDI8 operates on a single supply voltage-either 2.5 V ±5% or 3.3 V ±5%, as defined by its option code ('L' denotes 2.5 V, 'K' denotes 3.3 V). The 8N3SV75LC-0018CDI8 uses Option Code L (per part number decoding), confirming it is configured for 2.5 V operation, with corresponding LVPECL DC characteristics (VOH/VOL) and current draw (120–155 mA).

Can the VCXO pull range of the 8N3SV75LC-0018CDI8 be modified after shipment?

No, the absolute pull range (APR) and control voltage polarity of the 8N3SV75LC-0018CDI8 are factory-programmed and permanently stored in ROM; they cannot be altered in the field. The APR for this part is ±50 ppm (Option Code L), and the VC polarity is fixed-requiring external circuitry only for voltage translation, not reconfiguration.

Is the 8N3SV75LC-0018CDI8 pin-compatible with other IDT8N3SV75 variants in the CD package?

Yes, all IDT8N3SV75 devices in the CD package-including 8N3SV75LC-0018CDI8-share identical 6-pin assignments, mechanical footprint, and thermal profile. Pin functions (VC, OE, VEE, Q, nQ, VCC) and recommended layout practices (e.g., 0.1 µF local decoupling, 50 Ω differential termination) are consistent across the family.

What is the RMS phase jitter specification for the 8N3SV75LC-0018CDI8 at 156.25 MHz?

The 8N3SV75LC-0018CDI8 delivers 0.5 ps typical RMS phase jitter at 156.25 MHz over the 12 kHz to 20 MHz offset range, as specified in Table 5A of the datasheet. This value is measured under standard conditions (VCC = 2.5 V or 3.3 V, TA = –40°C to +85°C) and confirms compliance with OC-192 and 10GBASE-R jitter requirements.
