Infineon Technologies CYP15G0401DXB-BGC

Overview

CYP15G0401DXB-BGC from Cypress Semiconductor is a quad-channel HOTLink II™ transceiver IC for high-speed serial point-to-point 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 width. It operates on a single 3.3V supply, delivers 12 Gbps aggregate throughput, and targets backplane, video transport, and telecom infrastructure links.

For engineers reviewing the CYP15G0401DXB-BGC datasheet, CYP15G0401DXB-BGC pinout, CYP15G0401DXB-BGC application, or CYP15G0401DXB-BGC equivalent, key selection criteria include SMPTE/OBSAI compliance scope, per-channel BIST capability, skew alignment support, Elasticity Buffer configuration, and PECL driver termination requirements without external bias resistors.

Technical Context

The CYP15G0401DXB-BGC implements four independent transmit/receive channels with fully integrated PLL-based clock recovery and serialization/deserialization. Each channel supports selectable 8-bit, 16-bit, or 32-bit bonding modes and configurable input/output clocking (recovered vs. local reference).

Its MultiFrame™ Receive Framer provides bit- and byte-level alignment with K28.5 comma detection, while optional Elasticity Buffer (RX) and Phase Align Buffer (TX) enable jitter tolerance and phase compensation across bonded links. The device uses 0.25µm BiCMOS technology and requires no external PLL components.

FAQ

What is the maximum supported serial data rate for CYP15G0401DXB-BGC?

The CYP15G0401DXB-BGC supports a maximum serial data rate of 1500 MBaud per channel. This is confirmed in the official datasheet (Document #: 38-02002 Rev. *L, Page 2), which specifies the operating range as 195–1500 MBaud for the CYP variant. Note that CYW15G0401DXB extends to 1540 MBaud, but CYP does not.

Does CYP15G0401DXB-BGC require external termination resistors for its PECL outputs?

No. The device integrates source-matched 50Ω drivers for all PECL-compatible outputs (e.g., OUTA1±, OUTA2±), eliminating the need for external bias or termination resistors. This is explicitly stated in the Functional Description (Page 2): "No external bias resistors required" and "Source matched for 50Ω transmission lines."

Can CYP15G0401DXB-BGC operate without 8B/10B encoding?

Yes. The integrated 8B/10B encoder/decoder can be bypassed to accept pre-encoded or scrambled 10-bit data at the parallel interface. The datasheet (Page 2) states: "The integrated 8B/10B Encoder/Decoder may be bypassed for systems that present externally encoded or scrambled data at the parallel interface."

How many differential serial I/O pairs does CYP15G0401DXB-BGC provide?

The device provides eight differential serial I/O pairs: four dual-input (INA1±/INA2±, etc.) and four dual-output (OUTA1±/OUTA2±, etc.) per channel, totaling 16 differential terminals. Pin Configuration diagrams (Pages 6–7) confirm two dedicated PECL-compatible differential pairs per channel (A–D), with explicit labeling of ± signals.
