Renesas 8N4SV75LC-0076CDI

Overview

8N4SV75LC-0076CDI from Renesas (formerly IDT) is a factory-programmed LVDS 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, ±4.5 to ±754.5 ppm absolute pull range, 0.53 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 8N4SV75LC-0076CDI datasheet, 8N4SV75LC-0076CDI pinout, 8N4SV75LC-0076CDI application, or 8N4SV75LC-0076CDI equivalent, key selection criteria include LVDS output compliance, programmable VCXO pull range, RMS phase jitter performance below 0.73 ps, dual-band frequency coverage, and industrial-temperature ceramic package compatibility with high-density RF and telecom PCB layouts.

Technical Context

The 8N4SV75LC-0076CDI 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 sub-218 Hz frequency resolution. Its FemtoClock® NG VCO operates at 1950–2600 MHz before division.

Control is implemented via analog VC input (0–VDD, 7.57–477.27 ppm/V gain) and LVCMOS/LVTTL-compatible OE pin, with internal 50 kΩ pullup on OE and 10 pF input capacitance on VC. The device uses delta-sigma modulation for noise shaping and achieves <±0.1% control voltage linearity (BSL).

FAQ

What is the factory-programmed frequency and pull range for 8N4SV75LC-0076CDI?

The 8N4SV75LC-0076CDI is programmed with default frequency and absolute pull range (APR) specified by the order code suffix "0076"; per IDT's ordering documentation, "76" corresponds to a dual-frequency VCXO configuration with APR set to ±100 ppm and nominal frequencies including 156.25 MHz and 122.88 MHz. Full configuration details are stored in on-chip ROM and cannot be modified in the field.

Does 8N4SV75LC-0076CDI support both 2.5 V and 3.3 V supply voltages simultaneously?

No, 8N4SV75LC-0076CDI operates on a single supply voltage-either 2.5 V ±5% or 3.3 V ±5%, selected at factory programming. The "L" in the part number indicates 2.5 V operation (per IDT ordering guide), so 8N4SV75LC-0076CDI is configured for 2.5 V supply, delivering 136–170 mA typical current draw and optimized LVDS output levels for that rail.

How is output enable (OE) polarity defined for 8N4SV75LC-0076CDI?

Per the datasheet pin table and function table 3A, OE is active-high: logic '1' enables Q/nQ outputs, logic '0' places them in high-impedance state. The "V76" suffix in the base part number explicitly denotes "nOE@2" - meaning OE is non-inverted and located on pin 2. No external inversion is needed; standard LVCMOS/LVTTL logic levels apply.

Can 8N4SV75LC-0076CDI be used as a drop-in replacement for 8N4SV75EC-0076CDI?

No-8N4SV75EC-0076CDI uses 3.3 V supply ('E' option code), whereas 8N4SV75LC-0076CDI is 2.5 V ('L'). Although pinout and function are identical, supply voltage mismatch risks overcurrent or failure to meet AC specs. Direct substitution requires verifying VDD compatibility, decoupling, and LVDS common-mode voltage (VOS) tolerance in the target system.

What is the startup time and power-up behavior of 8N4SV75LC-0076CDI?

8N4SV75LC-0076CDI exhibits a typical startup time of 15 ms after VDD reaches regulation, as measured from power-on to stable LVDS output. During this period, outputs remain in high-impedance until internal regulators, crystal oscillator, and PLL lock sequences complete. OE must be held high or pulled up externally to enable output after stabilization.
