14.2 Gbps Asynchronous 4-Channel Signal Conditioner Data Sheet HMC7545 FEATURES 8 Gb, 10 Gb, 16 Gb active optical modules 8 Gb, 10 Gb, 16 Gb active copper cable assemblies Continuous time linear equalizer (CTLE) with up to 18 dB 1.5 Gb, 3 Gb, 6 Gb, 12 Gb SAS/SATA equalization PCIe 1.x, 2.0, 3.0 Loss of signal (LOS) detection with programmable threshold Broadband and automatic test and measurement and hysteresis Driver performance GENERAL DESCRIPTION Programmable differential swing: 400 mV p-p differential The HMC7545 is a unidirectional, quad-channel, protocol and to 900 mV p-p differential data rate agnostic, asynchronous signal conditioner, designed Programmable driver output with up to 12 dB de-emphasis for short and intermediate range optical modules, line cards, Automatic electrical idle and receiver detection and backplane applications operating at up to 14.2 Gbps. Output polarity inversion and automatic output squelch Each channel provides programmable input equalization, LOS Single supply (2.5 V or 3.3 V) and receiver detection, automatic output squelch, Low power operation: 80 mW per channel programmable output swing and output de-emphasis. Per lane power-down options Flexible configuration interface: pin strap, 2-wire interface, All high speed differential inputs and outputs of the HMC7545 or EEPROM are current mode logic (CML), terminated on-chip with 50 to the positive supply, and can be dc-coupled or ac-coupled. APPLICATIONS The device uses a single supply, 2.5 V or 3.5 V, and its typical QSFP+ direct attach active copper modules power dissipation is less than 80 mW per channel. 10 Gb, 40 Gb Ethernet and OTN line cards 10 Gb, 40 Gb backplane drivers The HMC7545 is packaged in a 36-lead, 4 mm 7 mm LFCSP 8 Gb, 16 Gb Fibre Channel and InfiniBand EDR line cards package and operates from 40C to +85C. and backplane drivers FUNCTIONAL BLOCK DIAGRAM VCCI VCCO LOS DETECT Rx DETECT IN0P OUT0P TO TO IN3P OUT3P DE- LIMITING VCCI CTLE VCCO EMPHASIS AMP IN0N OUT0N TO TO IN3N OUT3N RX EQ1 TXDOUT RX EQ0 TX EQ1 TX EQ0 INVERT TWI MST/SLV 2-WIRE INTERFACE TWISEL CONTROL SCK LOGIC EEPROM DONE SDA RESET SQUELCH GND Figure 1.
