Overview
The DS160PR1601ZDGT is a Texas Instruments PCIe 4.0 linear redriver supporting data rates up to 16 Gbps. It features 16 lanes with 32 total channels (16 transmit, 16 receive). The device operates on a single 3.3 V supply and supports x4, x8, and x16 bus widths. Key electrical parameters include an ultra-low latency of 130 ps, additive random jitter of 100 fs for PRBS data, and CTLE boosts of 16 dB at 8 GHz. It utilizes an NFBGA-354 package measuring 22.89 mm by 8.90 mm.
Feature Summary
- Integrates 64 AC coupling capacitors directly inside the package to reduce board space requirements.
- Provides analog EyeScan functionality to assist in redriver tuning, debugging, and remote monitoring.
- Supports seamless PCIe link training while preserving transmit preset signal characteristics.
- Includes automatic receiver detection specifically designed for PCIe use cases.
Applications
- Rack servers, microservers, and tower servers
- High performance computing systems
- Hardware accelerators
- Network attached storage and SAN/HBA cards
- Desktop PC motherboards
Procurement Notes
Verify the specific ordering suffix ZDGT against the manufacturer's current orderable addendum to confirm package type and tape-and-reel specifications. Ensure compatibility with I2C/SMBus or EEPROM programming interfaces required by the system design. Confirm that the NFBGA-354 footprint matches the PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when designing for PCIe 4.0 environments requiring low-latency signal regeneration without retimer complexity. Consider the integrated AC capacitors if board real estate is limited. Verify that the 16-lane configuration aligns with the target x16 bus width requirements. Ensure the system can accommodate the 3.3 V power supply and thermal dissipation needs associated with the active channel count.
Part Context
This part belongs to the DS160PR1601 series of linear redrivers from Texas Instruments. It is designed as a high-performance, low-power repeater to extend PCIe traces. The ZDGT suffix indicates the specific NFBGA-354 package variant used for surface-mount assembly.
Replacement Considerations
Check for pin-compatible alternatives within the same family, such as the DS320PR1601 for PCIe 5.0 applications, though speed differences apply. Verify that any substitute maintains the 16-lane architecture and 3.3 V operating voltage.
FAQ
Does the DS160PR1601 support UPI 2.0?
Yes, the device supports PCIe 4.0 and UPI 2.0 interfaces up to 16 Gbps.
What is the maximum CTLE boost provided by the receivers?
The continuous time linear equalizers (CTLE) provide boosts of 16 dB at 8 GHz.
How does the device handle link training?
It offers seamless support for PCIe link training, becoming part of the passive channel to allow best transmit and receive equalization settings.
