Product details
Overview
8N4SV75FC-0037CDI from Renesas (formerly IDT) is a factory-programmed LVDS 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, and 0.53 ps RMS phase jitter at 156.25 MHz - deployed in wireless infrastructure baseband timing and high-speed SerDes clocking.
For engineers reviewing the 8N4SV75FC-0037CDI datasheet, 8N4SV75FC-0037CDI pinout, 8N4SV75FC-0037CDI application, or 8N4SV75FC-0037CDI equivalent, key selection criteria include LVDS output compliance, industrial temperature operation (−40°C to +85°C), dual-frequency programmability, VCXO control voltage linearity (±0.1% BSL), and ceramic 5 mm × 7 mm × 1.55 mm package compatibility with high-density RF board layouts.
Technical Context
The 8N4SV75FC-0037CDI integrates a 114.285 MHz third-overtone crystal oscillator driving a fractional-N PLL with pre-divider (P), integer+fractional feedback divider (MINT/MFRAC), and post-divider (N), enabling sub-218 Hz frequency resolution. Its VCO operates at 1950–2600 MHz before division.
It implements LVDS differential output (Q/nQ), OE-controlled tri-state enable/disable, and VC input with programmable polarity and oscillator gain (7.57–477.27 ppm/V at 3.3 V). Configuration is stored in ROM and selected via FSEL logic, though this specific variant uses fixed dual-frequency programming per order code FC-0037.

Pinout & Package
6-lead ceramic CD package (5 mm × 7 mm × 1.55 mm), RoHS 6-compliant, with exposed pad not electrically connected. Pin 1 = VC (control voltage input), Pin 2 = OE (LVCMOS/LVTTL output enable), Pin 3 = GND, Pins 4–5 = Q/nQ (LVDS differential outputs), Pin 6 = VDD (2.5 V or 3.3 V supply).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VC (Pin 1) | VCXO tuning voltage input | Accepts 0–VDD control range; linearity ±0.1% BSL ensures predictable frequency vs. voltage response in closed-loop PLLs. |
| OE (Pin 2) | Output enable control | LVCMOS/LVTTL-compatible; logic high enables Q/nQ, logic low places outputs in high-impedance state - supports dynamic clock gating. |
| GND (Pin 3) | Power ground reference | Dedicated ground return path minimizes noise coupling into sensitive analog VCO and PLL circuitry. |
| Q (Pin 4) | LVDS positive output | Differential clock output with 247–454 mV swing; requires 100 Ω termination to match PCB trace impedance. |
| nQ (Pin 5) | LVDS negative output | Complementary to Q; common-mode voltage 1.13–1.31 V ensures robust noise immunity across temperature and supply variation. |
| VDD (Pin 6) | Power supply input | Supplies core logic, PLL, and LVDS driver; decoupling with 0.1 µF capacitor adjacent to pin is mandatory for <0.73 ps jitter performance. |

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; wider 10 kHz–210 MHz range; lower max APR (±100 ppm); higher phase noise (0.9 ps typical) | Limited to single-ended clock trees; unsuitable for high-speed differential SerDes interfaces | Select only if LVDS is unnecessary and cost sensitivity outweighs jitter performance. |
| AK20D01-001 | LVDS output; fixed 156.25 MHz; no VCXO function; ±20 ppm stability; 0.45 ps jitter | Cannot support frequency pulling or dual-frequency switching; lacks OE control | Choose when static, ultra-low-jitter reference is sufficient and VCXO flexibility is not required. |
Compared with Si510-PROG and AK20D01-001, the 8N4SV75FC-0037CDI uniquely delivers LVDS output, factory-programmed dual-frequency VCXO capability, and sub-0.73 ps jitter across 15–1300 MHz - making it optimal for telecom infrastructure where dynamic synchronization and differential signaling are mandatory.

FAQ
What is the factory-programmed frequency configuration for 8N4SV75FC-0037CDI?
The 8N4SV75FC-0037CDI is programmed with two precise default frequencies and an associated absolute pull range (APR) per Renesas' ordering code FC-0037. While exact frequencies are customer-specific and defined at time of order, the device supports any combination within 15.476–866.67 MHz and 975–1300 MHz ranges with 218 Hz resolution. The APR is set between ±4.5 and ±754.5 ppm during manufacturing and cannot be altered in the field.
Does 8N4SV75FC-0037CDI support both 2.5 V and 3.3 V supply operation?
Yes, the 8N4SV75FC-0037CDI supports either 2.5 V ±5% or 3.3 V ±5% supply voltage, with corresponding DC characteristics specified in Tables 4A–4B (power current) and 4D–4E (LVDS output levels). Power supply selection must be fixed at design time; the device does not auto-detect or dynamically switch between voltages. Decoupling capacitors must be sized appropriately for the chosen rail.
How is output enable (OE) functionality implemented on 8N4SV75FC-0037CDI?
The OE pin (Pin 2) is an LVCMOS/LVTTL-compatible input that controls the LVDS output drivers. When OE = logic high (≥2.0 V at 3.3 V supply), Q and nQ deliver active differential clock signals. When OE = logic low (≤0.8 V), both outputs enter high-impedance state - enabling clock domain isolation and reducing system-level EMI. Internal pull-up resistors (~50 kΩ) ensure default-enable behavior if left unconnected.
What is the significance of the "CD" package designation in 8N4SV75FC-0037CDI?
The "CD" suffix denotes a lead-free, 6-lead ceramic package measuring 5 mm × 7 mm × 1.55 mm, qualified to industrial temperature (−40°C to +85°C) and compliant with RoHS 6. This hermetic ceramic body provides superior thermal stability and moisture resistance versus plastic packages, critical for maintaining phase noise and frequency accuracy in telecom and outdoor RF applications where environmental stress is high.
Can 8N4SV75FC-0037CDI be used as a drop-in replacement for other IDT FemtoClock NG VCXOs?
No - the 8N4SV75FC-0037CDI is a specific orderable variant with fixed dual-frequency programming and APR defined by the FC-0037 code. It shares pinout and electrical interface with other 6-lead CD-package IDT8N4SV75 variants (e.g., 8N4SV75EC-xxxxCDI), but functional equivalence requires matching option codes (voltage, stability grade, OE location) and identical factory programming. Direct substitution without verification risks frequency mismatch or control polarity inversion.
