ADC0808S125HW/C1:1

Analog To Digital Converters (ADC) Overview

The ADC0808S125HW/C1:1 is a differential, high-speed, 8-bit Analog-to-Digital Converter (ADC) from NXP Semiconductors. It supports sampling frequencies up to 125 MHz and features selectable 1.8 V CMOS or LVDS clock inputs. The device utilizes a single 3.3 V analog supply and 1.8 V digital supplies. Key specifications include a maximum analog input frequency of 560 MHz, 2 clock cycles latency, and an integrated voltage regulator for the input common-mode reference. It operates within an industrial temperature range of −40 °C to +85 °C and is housed in an HTQFP48 package.

• 8-bit resolution with high-speed sampling up to 125 MHz
• Selectable 1.8 V CMOS or LVDS clock input modes
• Differential analog input with programmable acquisition control via Complete Conversion Signal (CCS)
• Integrated voltage regulator for input common-mode reference

Analog To Digital Converters (ADC) Applications

• 2.5G and 3G cellular base infrastructure radio transceivers
• Wireless access systems and Wireless Local Area Network (WLAN) infrastructure
• Fixed telecommunications and optical networking
• Tape drive applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix :1 indicates specific packaging or tape-and-reel configuration as defined by NXP documentation. Confirm that the HTQFP48 package variant matches the required PCB footprint dimensions. Ensure compatibility with 1.8 V logic levels for all static digital inputs and outputs before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 125 MHz sampling rate is sufficient; use the ADC0808S250 variant for speeds up to 250 MHz. Choose between CMOS or LVDS clock inputs based on the driving source capabilities. Ensure the design accommodates the 3.3 V analog supply and 1.8 V digital/output supplies. Verify that the differential input requirements align with the signal source impedance and common-mode voltage constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC0808S family, which includes variants optimized for different maximum sampling rates. The ADC0808S125HW/C1:1 is specifically rated for 125 MHz operation, distinguishing it from the higher-speed ADC0808S250HW/C1:1. Both share identical pinouts, functional blocks, and interface characteristics, differing primarily in their guaranteed maximum clock frequency performance.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC0808S250HW/C1:1 serves as a direct functional substitute offering higher speed (250 MHz) with identical pinout and interface specifications. No other cross-model replacements are confirmed in the provided datasheet.
