Renesas 8N3SV75LC-0099CDI8

Overview

8N3SV75LC-0099CDI8 from Renesas Electronics is a factory-programmed LVPECL voltage-controlled crystal oscillator (VCXO) with fourth-generation FemtoClock® NG PLL synthesis, supporting output frequencies from 15.476 MHz to 866.67 MHz and 975 MHz to 1,300 MHz, ±218 Hz frequency resolution, 0.5 ps RMS phase jitter at 156.25 MHz (12 kHz–20 MHz), and operation across –40°C to +85°C for wireless infrastructure timing.

For engineers reviewing the 8N3SV75LC-0099CDI8 datasheet, 8N3SV75LC-0099CDI8 pinout, 8N3SV75LC-0099CDI8 application, or 8N3SV75LC-0099CDI8 equivalent, key selection considerations include its programmable APR (±4.5 to ±754.5 ppm), LVCMOS/LVTTL-compatible OE control, dual supply support (2.5 V/3.3 V), 6-pin ceramic 5 mm × 7 mm package, and guaranteed phase noise performance down to –145 dBc/Hz at 10 MHz offset.

Technical Context

The 8N3SV75LC-0099CDI8 integrates a 114.285 MHz fundamental-mode crystal 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 high-resolution frequency synthesis across two disjoint bands. Its FemtoClock® NG VCO operates at 1950–2600 MHz before division.

Control is implemented via analog VC input (0–VCC, 500 kΩ impedance) with programmable oscillator gain (7.57–477.27 ppm/V at 3.3 V), linearity (±0.1% BSL), and modulation bandwidth (100 kHz); output enable (OE) provides LVCMOS/LVTTL-compatible tri-state control of differential Q/nQ LVPECL outputs terminated into 50 Ω to VCC – 2 V.

FAQ

What is the factory-programmed output frequency of the 8N3SV75LC-0099CDI8?

The 8N3SV75LC-0099CDI8 is factory-programmed to 156.25 MHz, as indicated by the "0099" order code in its part number. This frequency is commonly used for 10G Ethernet, OTU2, and CPRI applications. The device retains full VCXO functionality - allowing fine-tuning around 156.25 MHz within its programmed absolute pull range (APR). No external programming is required to operate at this frequency.

Does the 8N3SV75LC-0099CDI8 support both 2.5 V and 3.3 V supply voltages?

Yes, the 8N3SV75LC-0099CDI8 supports either 2.5 V ±5% or 3.3 V ±5% supply voltage, as specified in its DC electrical characteristics tables. The supply voltage is selected at factory programming and encoded in the option code (e.g., "K" = 3.3 V ±5%, ±20 ppm). The 8N3SV75LC-0099CDI8 uses the "L" option code, confirming 2.5 V operation. Both supply configurations maintain identical jitter and phase noise performance.

What is the meaning of the "CDI8" suffix in 8N3SV75LC-0099CDI8?

The "CDI8" suffix breaks down as follows: "CD" = 6-lead ceramic 5 mm × 7 mm RoHS-compliant package; "I" = industrial temperature range (–40°C to +85°C); "8" = tape-and-reel packaging (1,000 pcs/reel). This confirms the 8N3SV75LC-0099CDI8 is a surface-mount, lead-free, high-reliability VCXO qualified for extended-temperature deployment in telecom infrastructure.

Can the 8N3SV75LC-0099CDI8 be used without an external termination network?

No - the 8N3SV75LC-0099CDI8's LVPECL outputs (Q/nQ) require proper 50 Ω termination to VCC – 2 V for correct logic levels and signal integrity. For 2.5 V supply, this approximates termination to ground; for 3.3 V, it requires resistive networks (e.g., 84 Ω to VCC and 125 Ω to ground). Omitting termination causes degraded VOH/VOL, increased jitter, and potential signal reflection - directly impacting the 8N3SV75LC-0099CDI8's specified 0.5 ps RMS phase jitter performance.

How does the OE pin function on the 8N3SV75LC-0099CDI8?

The OE (Output Enable) pin on the 8N3SV75LC-0099CDI8 is an LVCMOS/LVTTL-compatible active-high input. When OE = 1 (≥2.0 V at 3.3 V supply), Q/nQ outputs are enabled; when OE = 0 (≤0.8 V), both outputs enter high-impedance state. This allows dynamic clock gating in power-sensitive systems. The 8N3SV75LC-0099CDI8 features internal 50 kΩ pull-up on OE, simplifying interface design - no external resistor needed unless inverted logic is required.
