Renesas 8N3SV75AC-0094CDI

Overview

8N3SV75AC-0094CDI from Renesas Electronics is a factory-programmed LVPECL voltage-controlled crystal oscillator (VCXO) with fourth-generation FemtoClock® NG PLL synthesis, delivering programmable output frequencies from 15.476 MHz to 866.67 MHz and 975 MHz to 1,300 MHz at ≤218 Hz resolution, ±20 ppm total stability over -40°C to +85°C, and 0.44 ps RMS phase jitter (500–1300 MHz band), used in wireless infrastructure baseband timing and high-speed SerDes clocking.

For engineers reviewing the 8N3SV75AC-0094CDI datasheet, 8N3SV75AC-0094CDI pinout, 8N3SV75AC-0094CDI application, or 8N3SV75AC-0094CDI equivalent, key selection considerations include its dual-band frequency coverage, factory-set ±20 ppm total stability (Option K), LVPECL differential output drive capability, OE-controlled output enable, and ceramic 5 mm × 7 mm × 1.55 mm CD package compatibility with high-density RF and telecom PCB layouts.

Technical Context

The 8N3SV75AC-0094CDI integrates a 114.285 MHz third-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), enabling precise 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 linearity (±0.1% BSL), while OE pin enables LVCMOS/LVTTL-compatible output disable. The device uses internal ROM for factory-configured frequency, pull range, and control polarity.

FAQ

What is the factory-programmed frequency and pull range for 8N3SV75AC-0094CDI?

The 8N3SV75AC-0094CDI is factory-programmed to a specific default frequency and absolute pull range (APR) encoded in the "0094" suffix per IDT's ordering documentation. While the exact values require cross-referencing the FemtoClock NG Ceramic-Package XO and VCXO Ordering Product Information document, the "K" option code confirms ±20 ppm total stability and 3.3 V operation. The 8N3SV75AC-0094CDI does not support field reprogramming - configuration is permanently stored in ROM.

Does 8N3SV75AC-0094CDI support 2.5 V supply voltage?

No, the 8N3SV75AC-0094CDI does not support 2.5 V operation. The "A" in the part number denotes Option Code A, which specifies 3.3 V ±5% supply voltage and ±100 ppm temperature stability - however, the "K" in the full marking IDT8N3SV75KC-0094CDI (per Table 9) overrides this, confirming the actual configuration is Option K: 3.3 V ±5% supply with ±20 ppm total stability. Devices with 2.5 V support use Option Codes B, F, or L.

What is the maximum modulation bandwidth of the VC input on 8N3SV75AC-0094CDI?

The VC input modulation bandwidth for the 8N3SV75AC-0094CDI is 100 kHz, as specified in Table 5B of the datasheet. This defines the highest frequency at which the control voltage can dynamically adjust the output frequency while maintaining linearity and intended pull-range behavior. Exceeding 100 kHz may result in attenuation or phase lag in the tuning response, affecting closed-loop PLL performance in applications like jitter attenuation or frequency modulation.

Can 8N3SV75AC-0094CDI be used as a drop-in replacement for 8N3SV75EC-0094CDI?

No, the 8N3SV75AC-0094CDI is not a drop-in replacement for 8N3SV75EC-0094CDI. Although both share identical package, pinout, and LVPECL output structure, they differ in Option Code: "A" vs. "E" indicates distinct stability grades (±100 ppm vs. ±50 ppm) and potentially different factory-programmed APR and VC polarity settings. Substituting without verifying datasheet-specified electrical and functional compatibility risks timing margin violations in stability-critical systems.

How is RMS phase jitter measured for 8N3SV75AC-0094CDI at frequencies outside 156.25 MHz?

RMS phase jitter for the 8N3SV75AC-0094CDI is measured across three frequency bands per Table 5A: 15–100 MHz (0.74–1.2 ps), 100–500 MHz (0.52–0.90 ps), and 500–1300 MHz (0.44–0.77 ps), all integrated from 12 kHz to 20 MHz. These values are characterized at the specified output frequency using dedicated phase noise measurement equipment; the 8N3SV75AC-0094CDI's jitter scales predictably with carrier frequency due to its high-reference PLL architecture centered on 114.285 MHz.
