Infineon Technologies CYP15G0401DXB-BGI

Overview

CYP15G0401DXB-BGI from Cypress Semiconductor is a quad-channel HOTLink II™ transceiver IC for high-speed serial interconnects, supporting 195–1500 MBaud per channel with 8B/10B encoding, dual PECL-compatible differential I/O per channel, and synchronous multi-channel bonding (up to 32-bit). It enables point-to-point or point-to-multipoint links over fiber, copper, or PCB traces in video backplanes and telecom infrastructure.

For engineers reviewing the CYP15G0401DXB-BGI datasheet, CYP15G0401DXB-BGI pinout, CYP15G0401DXB-BGI application, or CYP15G0401DXB-BGI equivalent, key selection criteria include SMPTE-agnostic data rate range, per-channel BIST capability, selectable elasticity/phase-align buffers, and JTAG boundary scan support for production testability.

Technical Context

The CYP15G0401DXB-BGI implements four independent transmit/receive channels with fully integrated PLL-based clock recovery and serialization/deserialization. Each channel supports configurable 8-bit, 16-bit, or 32-bit bonding modes and operates with either local reference clock or recovered clock alignment.

It features a MultiFrame™ Receive Framer with comma detection (K28.5), bit/byte alignment, and low-latency framer option; the transmit path includes optional phase-align buffer and selectable parity generation/checking, while the receive path offers optional elasticity buffer and per-channel Link Quality Indicator (analog/digital signal detect).

FAQ

What is the maximum supported data rate per channel for CYP15G0401DXB-BGI?

The CYP15G0401DXB-BGI supports serial data rates from 195 MBaud to 1500 MBaud per channel, with aggregate throughput up to 12 Gbps across all four channels. This range covers industry standards including CPRI, DVB-ASI, and Gigabit Ethernet physical layers, and is confirmed in Cypress Document #38-02002 Rev. *L.

Does CYP15G0401DXB-BGI require external PLL components?

No. The device integrates fully self-contained PLLs for both transmit and receive paths, eliminating the need for external loop filters, VCOs, or passive components. This simplifies layout, improves jitter performance, and reduces bill-of-materials cost, as specified in the functional description on page 2 of the datasheet.

Can CYP15G0401DXB-BGI operate with externally encoded data?

Yes. The integrated 8B/10B encoder/decoder can be bypassed via configuration pins, allowing direct transport of pre-encoded or scrambled data presented at the LVTTL parallel interface. This mode is explicitly supported for systems that perform encoding upstream, as described in the functional block diagram on page 4.

Is JTAG boundary scan supported on CYP15G0401DXB-BGI?

Yes. The device implements full IEEE 1149.1 JTAG boundary scan with TCK, TMS, TDI, TDO, and TRSTZ pins. It enables at-speed interconnect testing, fault isolation, and in-system programming, as documented in the pin descriptions section (page 8) and functional overview (page 2).
