DS160PR1601ZDGR

Overview

The DS160PR1601 is a 16-lane linear redriver supporting data rates up to 16 Gbps for PCIe 4.0 and UPI 2.0 interfaces. It features 32 channels (16 Tx, 16 Rx) in an 8.90 mm × 22.80 mm BGA package. Key electrical parameters include a CTLE boost of 16 dB at 8 GHz, ultra-low latency of 130 ps, and additive random jitter of 100 fs for PRBS data. The device operates on a single 3.3 V supply with low active power consumption of 160 mW per channel. It integrates 64 AC coupling capacitors on TX pins and provides excellent RX/TX return loss of −13 dB at 8 GHz.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official orderable addendum to ensure correct package type and temperature range. Confirm that the component source is authorized to guarantee production data integrity. Check for any recent documentation updates or revision history notes that may affect implementation details. Ensure compatibility with existing system design constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing high-speed interconnects requiring transparent equalization for PCIe 4.0 or UPI 2.0 links. The integrated AC coupling capacitors simplify layout by reducing external component count. Consider the 130 ps latency and low jitter specifications for applications sensitive to signal delay. Verify that the 3.3 V single-supply requirement aligns with the target system's power architecture and thermal management capabilities.

Part Context

This device belongs to Texas Instruments' DS160PR series of linear redrivers designed for high-speed serial interfaces. It serves as a signal integrity solution for extending trace lengths on PCBs where passive channels suffer from excessive insertion loss. The part is engineered to maintain signal transparency while providing necessary equalization to open closed eyes caused by inter-symbol interference.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Designers should consult the manufacturer's product selection guide for compatible alternatives within the same family or cross-reference with other vendors based on pinout and electrical specifications.
