For engineers reviewing the ISLA216S25IR48EV1Z datasheet, ISLA216S25IR48EV1Z pinout, ISLA216S25IR48EV1Z application, or ISLA216S25IR48EV1Z equivalent, key selection criteria include JESD204B Subclass 2 compliance, SPI-configurable clock divider for 2x/4x harmonic clocking, fine gain/offset adjustment, and thermal performance enabled by its 7 mm × 7 mm QFN package with exposed paddle.

Technical Context

The ISLA216S25IR48EV1Z implements a pipelined ADC core with integrated JESD204B transmitter supporting two lanes, Subclass 0 and Subclass 2 operation, and deterministic latency via SYNC input synchronization. Its SERDES PLL has 2.2 MHz bandwidth and achieves <5 ps RMS added random jitter.

It uses separate 1.8 V analog (AVDD/AVSS) and digital (OVDD/OVSS) supply domains, includes programmable nap/sleep modes reducing power to 6 mW, and supports SPI-controlled calibration, test patterns, and transport-layer configuration - all while maintaining full 250 MSPS sampling capability.

FAQ

What is the primary function of the ISLA216S25IR48EV1Z?

The ISLA216S25IR48EV1Z is a 16-bit, 250 MSPS analog-to-digital converter with JESD204B serial output. Its primary function is high-fidelity digitization of wideband analog signals - such as IF/RF inputs in radar and communications systems - while delivering deterministic latency, low power (887 mW), and robust thermal performance in a 7 mm × 7 mm QFN package.

Does the ISLA216S25IR48EV1Z support JESD204B Subclass 2 operation?

Yes, the ISLA216S25IR48EV1Z supports JESD204B Subclass 2 operation, enabling deterministic latency and multi-chip synchronization via the SYNCP/SYNCN inputs. This capability is essential for coherent sampling across multiple ISLA216S25IR48EV1Z devices in phased-array radar or beamforming applications.

What are the power consumption modes of the ISLA216S25IR48EV1Z?

The ISLA216S25IR48EV1Z offers three operational power states: normal mode (887 mW at 250 MSPS), nap mode (323 mW), and sleep mode (6 mW). Nap mode retains configuration and enables fast 5 µs wakeup; sleep mode disables most circuitry for ultra-low standby power with 1 ms wakeup time - ideal for burst-mode systems.

Can the ISLA216S25IR48EV1Z accept harmonic clock inputs?

Yes, the ISLA216S25IR48EV1Z includes a programmable clock divider accessible via SPI that supports 2× and 4× harmonic sampling clock inputs. This allows use of lower-frequency, lower-jitter clock sources - simplifying clock tree design while maintaining 250 MSPS effective sampling rate.

What package type and thermal characteristics does the ISLA216S25IR48EV1Z have?

The ISLA216S25IR48EV1Z uses a 48-lead QFN package measuring 7 mm × 7 mm with an exposed thermal pad connected to AVSS. Its thermal resistance is θ_JA = 24°C/W and θ_JC = 0.4°C/W, enabling effective heat dissipation in high-power density layouts typical of RF and test equipment applications.
