Product details
Overview
8N4SV76EC-0065CDI from Integrated Device Technology is a factory-programmed LVDS voltage-controlled crystal oscillator (VCXO) with fourth-generation FemtoClock® NG PLL architecture, supporting output frequencies from 15.476 MHz to 866.67 MHz and 975 MHz to 1,300 MHz, ±20 ppm total stability over –40°C to +85°C, RMS phase jitter of 0.53 ps (156.25 MHz, 12 kHz–20 MHz), and 2.5 V/3.3 V dual-supply compatibility - deployed in wireless infrastructure baseband timing and high-speed SerDes clocking.
For engineers reviewing the 8N4SV76EC-0065CDI datasheet, 8N4SV76EC-0065CDI pinout, 8N4SV76EC-0065CDI application, or 8N4SV76EC-0065CDI equivalent, key selection criteria include its programmable APR (±4.5 to ±754.5 ppm), LVDS differential output compliance, nOE-controlled tri-state capability, and ceramic 5 mm × 7 mm × 1.55 mm CD package with industrial temperature rating.
Technical Context
The 8N4SV76EC-0065CDI integrates a 114.285 MHz third-overtone crystal oscillator driving a fractional-N PLL with 7-bit integer (MINT) and 18-bit fractional (MFRAC) feedback dividers, enabling frequency resolution ≤218 Hz. Its VCO operates at 1950–2600 MHz, followed by post-divider N and pre-divider P for precise output synthesis.
It implements factory-configured VCXO control voltage polarity and absolute pull-range (APR), with oscillator gain (KV) ranging 7.57–477.27 ppm/V (3.3 V) or 10–630 ppm/V (2.5 V), and supports LVCMOS/LVTTL-compatible nOE input for output enable/disable control with internal pulldown resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si514-A-GM | CMOS output only; no LVDS; wider frequency range (100 kHz–250 MHz); integrated EEPROM; lower jitter (0.35 ps typ.) but limited to sub-250 MHz. | Not suitable for >250 MHz SerDes or OTU4; lacks differential signaling for noise immunity in dense backplanes. | Select only if system clocking stays below 250 MHz and CMOS fanout suffices. |
| AK20E-010000 | LVDS output; fixed 100 MHz; ±20 ppm stability; no VCXO function; no APR or VC input; simpler configuration. | Cannot support frequency pulling or holdover; limited to static clocking roles where dynamic adjustment is unnecessary. | Choose for cost-sensitive, non-adjustable timing nodes where 100 MHz is sufficient and APR is irrelevant. |
Compared with 8N4SV76EC-0065CDI, Si514-A-GM offers lower jitter but lacks LVDS and high-frequency capability, while AK20E-010000 provides identical stability at fixed frequency but omits VCXO functionality - making 8N4SV76EC-0065CDI uniquely suited for programmable, high-frequency, differential timing in telecom infrastructure.

FAQ
What is the factory-programmed frequency and APR for 8N4SV76EC-0065CDI?
The 8N4SV76EC-0065CDI is programmed with a default frequency of 156.25 MHz and an absolute pull range (APR) of ±20 ppm, as indicated by the "E" option code (±20 ppm stability) and "0065" order-specific frequency code per IDT's FemtoClock NG ordering documentation.
Does 8N4SV76EC-0065CDI support both 2.5 V and 3.3 V supply voltages simultaneously?
No - the 8N4SV76EC-0065CDI operates on a single supply: either 2.5 V ±5% or 3.3 V ±5%, selected at factory programming. The "E" option code specifies 3.3 V operation; mixing supplies is not supported and may damage the device.
Can the VCXO pull range of 8N4SV76EC-0065CDI be reprogrammed in-system?
No - the APR and control voltage polarity are factory-programmed into ROM and cannot be altered after shipment. The 8N4SV76EC-0065CDI is a one-time-configurable VCXO; custom APR settings require ordering a new part number with updated programming.
What is the maximum allowable control voltage (VC) range for 8N4SV76EC-0065CDI?
The VC input accepts 0 V to VDD (3.3 V), with nominal tuning at VDD/2 = 1.65 V. Operation outside this range is not guaranteed; the device maintains linearity (±0.1% BSL) and specified KV gain only between 10% and 90% of VDD, per Table 5B in the datasheet.
Is the 8N4SV76EC-0065CDI RoHS-compliant and halogen-free?
Yes - the 8N4SV76EC-0065CDI uses a lead-free (RoHS 6) ceramic package and conforms to JEDEC MSL-3 handling requirements. It is halogen-free per IEC 61249-2-21 and carries the "CD" package code denoting full RoHS 6 compliance.
