Product details
Overview
8N0SV75KA-0116CDI8 from Integrated Device Technology is a LVCMOS dual-frequency programmable VCXO with factory-programmed output frequencies of 114.285 MHz and 156.25 MHz, ±20 ppm temperature stability (Option K), 0.65 ps RMS phase jitter (12 kHz–20 MHz), 2.5 V supply, and -40°C to 85°C industrial operating range - used in wireless infrastructure baseband timing and telecom PLL synchronization.
For engineers reviewing the 8N0SV75KA-0116CDI8 datasheet, 8N0SV75KA-0116CDI8 pinout, 8N0SV75KA-0116CDI8 application, or 8N0SV75KA-0116CDI8 equivalent, key selection criteria include dual-frequency switching via FSEL, VCXO control voltage linearity (±0.1% BSL), absolute pull-range of ±4.5 to ±754.5 ppm, LVCMOS output drive strength (14 Ω at 3.3 V), and ceramic 5 mm × 7 mm × 1.55 mm package compatibility with high-density RF layouts.
Technical Context
The 8N0SV75KA-0116CDI8 integrates a 3rd-overtone 114.285 MHz crystal oscillator with a fourth-generation FemtoClock® NG PLL featuring fractional-N synthesis (MINT + MFRAC), 2-bit pre-divider (P), and 7-bit post-divider (N). It supports immediate frequency switching between two factory-configured outputs using the FSEL pin.
Its VCXO architecture uses an analog control voltage (VC) input with programmable oscillator gain (7.57–477.27 ppm/V depending on ADC_GAIN setting) and 100 kHz modulation bandwidth. The device implements delta-sigma noise shaping to minimize phase noise across its 15.476–260 MHz output range while maintaining <1 ms frequency settling after FSEL transition.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCXO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-PROG | Programmable single-frequency XO/VCXO (not dual-frequency); 0.8 ps jitter @ 156.25 MHz; 3.3 V only; 7-pin SOIC package. | Lacks FSEL-driven dual-frequency capability; requires external configuration EEPROM or I²C host. | Select when single-frequency flexibility outweighs dual-output convenience and board space permits larger SOIC footprint. |

FAQ
What are the factory-programmed frequencies of the 8N0SV75KA-0116CDI8?
The 8N0SV75KA-0116CDI8 is factory-programmed to output 114.285 MHz and 156.25 MHz - corresponding to common telecom and Ethernet reference frequencies. These values are fixed per the order code "0116" and cannot be altered in the field. The FSEL pin selects between them with sub-millisecond switching.
Does the 8N0SV75KA-0116CDI8 support 3.3 V operation?
No, the 8N0SV75KA-0116CDI8 is configured for 2.5 V operation only, as indicated by Option Code "K" in the part number. Its DC characteristics (VCC = 2.375–2.625 V, ICC = 124–148 mA) and LVCMOS output drive (17 Ω typical) are specified exclusively for 2.5 V supply - using 3.3 V violates absolute maximum ratings.
How is the absolute pull-range (APR) set on the 8N0SV75KA-0116CDI8?
The APR of the 8N0SV75KA-0116CDI8 is factory-programmed to a fixed value within ±4.5 to ±754.5 ppm, determined by the "0116" configuration code. It is not user-adjustable in-circuit; the internal ADC_GAIN register is pre-configured during manufacturing and inaccessible post-shipment.
What is the significance of the "CDI8" suffix in 8N0SV75KA-0116CDI8?
"CD" denotes the lead-free 6-lead ceramic 5 mm × 7 mm × 1.55 mm package; "I" indicates industrial temperature range (-40°C to +85°C); "8" specifies tape-and-reel packaging. Together, "CDI8" confirms the device's physical form factor, environmental rating, and shipping format - all critical for automated assembly and thermal reliability.
Can the DNU pin (Pin 5) be connected to ground on the 8N0SV75KA-0116CDI8?
Yes, Pin 5 (DNU) has no internal connection and may be grounded per IDT layout recommendations to reduce potential EMI coupling. However, it must never be tied to VCC or driven actively; leaving it floating is also acceptable but grounding improves noise immunity in high-density RF PCBs.
