Renesas ISLA110P50IR72EV1Z

Overview

ISLA110P50IR72EV1Z from Renesas Electronics is a 10-bit, 500MSPS analog-to-digital converter using FemtoCharge™ technology on standard CMOS. It employs dual time-interleaved 250MSPS ADC cores with integrated Interleave Engine (I2E) for automatic offset/gain/sample-time skew correction, delivers 60.6dBFS SNR at 190MHz input, and targets high-speed data acquisition in radar and broadband communications systems.

For engineers reviewing the ISLA110P50IR72EV1Z datasheet, ISLA110P50IR72EV1Z pinout, ISLA110P50IR72EV1Z application, or ISLA110P50IR72EV1Z equivalent, key selection factors include its 1.15GHz analog input bandwidth, 90fs clock jitter, LVDS/CMOS output configurability, 72-lead QFN package with exposed paddle, and industrial temperature range (-40°C to +85°C).

Technical Context

The ISLA110P50IR72EV1Z implements a pipelined successive approximation architecture with 12-cycle core latency and 17-cycle total pipeline latency. Its dual-core time-interleaving relies on internal 500MHz clock management-no external interleaving logic required-and uses proprietary charge-domain conversion techniques for high linearity and low power.

I2E calibration operates in Track or Hold mode, correcting inter-core mismatches in real time across voltage and temperature variations. The device supports programmable gain/offset/skew control, Nap/Sleep modes (179mW and 34mW power states), and synchronous clock divider reset for multi-chip time alignment.

FAQ

What is the maximum analog input frequency supported by the ISLA110P50IR72EV1Z?

The ISLA110P50IR72EV1Z supports a full-power analog input bandwidth of 1.15GHz, enabling direct sampling of signals up to the third Nyquist zone. At 500MSPS, this allows digitization of RF carriers up to ~1.15GHz with usable SNR, as confirmed by typical performance curves showing 60.1dBFS SNR at 495MHz and 59.7dBFS at 605MHz. Performance degrades gradually beyond that due to aliasing and bandwidth roll-off.

Does the ISLA110P50IR72EV1Z require external calibration circuitry?

No, the ISLA110P50IR72EV1Z integrates the proprietary Interleave Engine (I2E) that performs automatic real-time correction of offset, gain, and sample-time skew mismatches between its dual 250MSPS cores. This eliminates the need for external calibration hardware or firmware algorithms-calibration is invoked via SPI commands or automatically at power-on when RESETN is asserted correctly.

What digital output formats does the ISLA110P50IR72EV1Z support?

The ISLA110P50IR72EV1Z supports three selectable data formats via the OUTFMT pin: Two's Complement (default), Gray Code, and Offset Binary. Output interface mode (LVDS or LVCMOS) is controlled independently by the OUTMODE pin. All formats are delivered synchronously with the sample clock and exhibit fixed 17-cycle pipeline latency.

How does the Nap and Sleep mode functionality work on the ISLA110P50IR72EV1Z?

The ISLA110P50IR72EV1Z implements two low-power states: Nap mode (179mW) reduces dynamic power while retaining configuration and enabling 2.75µs wakeup; Sleep mode (34mW) shuts down most circuitry except SPI interface and resets internal state, requiring 1ms wakeup. Both are controlled via the tri-level NAPSLP pin and retain SPI accessibility during entry/exit.

Can the ISLA110P50IR72EV1Z be synchronized across multiple devices?

Yes, the ISLA110P50IR72EV1Z supports precise multi-chip synchronization using the CLKDIVRSTP and CLKDIVRSTN pins. When driven synchronously, these inputs reset the internal clock dividers across multiple devices, aligning their sampling phases to within picoseconds-essential for beamforming and MIMO systems requiring coherent sampling.
