CYP15G0401DXB-BGI

Telecom Overview

The CYP15G0401DXB is a Quad HOTLink II Transceiver manufactured by Infineon Technologies (formerly Cypress Semiconductor). It operates as a point-to-point or point-to-multipoint communications building block for high-speed serial links. The device supports serial data rates from 195 to 1500 MBaud per link, with an aggregate throughput of 12 Gbits/second. It features four independent byte-wide channels that can be bonded into two 16-bit or one 32-bit channel. The transceiver includes integrated 8B/10B encoding and decoding, selectable parity check/generate, and internal phase-locked loops. It utilizes a single 3.3V supply and is housed in a 256-ball thermally enhanced BGA package.

Telecom Feature Summary

• Supports multiple industry standards including ESCON, DVB-ASI, Fibre Channel, Gigabit Ethernet, CPRI, OBSAI-RP3, SMPTE 259M, and SMPTE 292M.
• Features selectable multi-channel bonding options allowing operation as four 8-bit, two 16-bit, or one 32-bit channel.
• Includes built-in self-test (BIST) hardware for at-speed link testing and per-channel Link Quality Indicators.
• Integrates dual differential PECL-compatible serial inputs and outputs with internal DC-restoration and signaling-rate controlled edge-rates.

Telecom Applications

• Interconnecting backplanes on switches, routers, and servers.
• Video transmission systems requiring high-speed parallel-to-serial conversion.
• High-performance computing architectures utilizing wide bus transport across significant distances.

Telecom Procurement Notes

Verify the specific suffix variant required for your application: CYP15G0401DXB for general use, CYW15G0401DXB for OBSAI-RP3 compliance up to 1540 MBaud, and CYV15G0401DXB for SMPTE 259M/292M compliance. Confirm Pb-free package availability if environmental regulations apply. Ensure the source document matches the exact part number to avoid functional discrepancies between variants.

Telecom Selection Notes

Select this component when replacing legacy parallel interfaces with high-speed serial links requiring skew alignment and multi-byte offset support. Choose the appropriate suffix based on target protocol compliance; standard CYP15G0401DXB covers most applications below 1500 MBaud. Consider the CYW variant if operating near the upper limit of 1540 MBaud for OBSAI compliance. Verify system clocking requirements against the selectable input/output clocking options.

Telecom Part Context

This device belongs to the second-generation HOTLink family, extending previous generations with higher integration and faster data rates while maintaining serial-link compatibility. It is designed to replace parallel interfaces in demanding environments. The Quad HOTLink II architecture allows flexible configuration of transmit and receive paths to accommodate various system bandwidth needs without external PLL components.

Telecom Replacement Considerations

Direct substitutes include CYW15G0401DXB and CYV15G0401DXB within the same family. These variants share the same pinout and core functionality but differ in specified maximum operating data rates and protocol compliance certifications. Ensure the replacement variant meets the specific timing and signaling requirements of the target application.
