HMC7545

Data Sheet 14.2 Gbps Asynchronous 4-Channel Signal Conditioner HMC7545 FEATURES 8 Gb, 10 Gb, 16 Gb active optical modules Continuous time linear equalizer (CTLE) with up to 18 dB equalization Loss of signal (LOS) detection with programmable threshold and hysteresis 8 Gb, 10 Gb, 16 Gb active copper cable assemblies 1.5 Gb, 3 Gb, 6 Gb, 12 Gb SAS/SATA PCIe 1.x, 2.0, 3.0 Broadband and automatic test and measurement Driver performance Programmable differential swing: 400 mV p-p differential to 900 mV p-p differential Programmable driver output with up to 12 dB de-emphasis Automatic electrical idle and receiver detection Output polarity inversion and automatic output squelch Single supply (2.5 V or 3.3 V) Low power operation: 80 mW per channel Per lane power-down options GENERAL DESCRIPTION The HMC7545 is a unidirectional, quad-channel, protocol and data rate agnostic, asynchronous signal conditioner, designed for short and intermediate range optical modules, line cards, and backplane applications operating at up to 14.2 Gbps. Each channel provides programmable input equalization, LOS and receiver detection, automatic output squelch, programmable output swing and output de-emphasis. Flexible configuration interface: pin strap, 2-wire interface, or EEPROM All high speed differential inputs and outputs of the HMC7545 are current mode logic (CML), terminated on-chip with 50 Ω to APPLICATIONS the positive supply, and can be dc-coupled or ac-coupled.
