DS25MB200 www.ti.com SNLS220G – MARCH 2006 – REVISED APRIL 2013 DS25MB200 Dual 2.5 Gbps 2:1/1:2 CML Mux/Buffer with Transmit Pre-Emphasis and Receive Equalization Check for Samples: DS25MB200 FEATURES DESCRIPTION • • • • The DS25MB200 is a dual signal conditioning 2:1 multiplexer and 1:2 fan-out buffer designed for use in backplane redundancy applications. Signal conditioning features include input equalization and programmable output pre-emphasis that enable data communication in FR4 backplanes up to 2.5 Gbps. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. All output drivers have 4 selectable steps of pre-emphasis to compensate for transmission losses from long FR4 backplanes and reduce deterministic jitter. The pre-emphasis levels can be independently controlled for the line-side and switch-side drivers. The internal loopback paths from switch-side input to switch-side output enable atspeed system testing. All receiver inputs are internally terminated with 100Ω differential terminating resistors. All drivers are internally terminated with 50Ω to VCC. 1 2 • • • • • • 0.6–2.5 Gbps Low Jitter Operation Fixed Input Equalization Programmable Output Pre-Emphasis Independent Switch and Line Side PreEmphasis Controls Programmable Switch-Side Loopback Modes On-Chip Terminations HBM ESD Rating 6 kV on All Pins +3.3V Supply Lead-Less WQFN-48 Package (7mm x 7mm x 0.8mm, 0.5mm Pitch) -40°C to +85°C Operating Temperature Range APPLICATIONS • • Backplane or Cable Driver Redundancy and Signal Conditioning Applications Functional Block Diagram Switch Side Line Side LO_0 ± MUX_S0 EQ SIA_0 ± EQ SIB_0 ± PRE_L LB0A Port 0 SOA_0 ± PRE_S LI_0 ± SOB_0 ± EQ PRE_S LB0B LO_1 ± EQ SIA_1 ± EQ SIB_1 ± PRE_L MUX_S1 LB1A Port 1 SOA_1 ± PRE_S LI_1 ± SOB_1 ± EQ PRE_S LB1B PreL_0 PreL_1 PreS_0 PreS_1 Pre-emphasis Control PRE_L VCC PRE_S GND RSV All CML inputs and outputs must be AC coupled for optimal performance. 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Each VCC pin should be connected to the VCC plane through a low inductance path, typically with a via located as close as possible to the landing pad of the VCC pin.

Each ground pin should be connected to the ground plane through a low inductance path, typically with a via located as close as possible to the landing pad of the GND pin. GND DAP P Die Attach Pad (DAP) is the metal contact at the bottom side, located at the center of the WQFN-48 package. It should be connected to the GND plane with at least 4 via to lower the ground impedance and improve the thermal performance of the package. POWER Functional Description The DS25MB200 is a signal conditioning 2:1 multiplexer and a 1:2 buffer designed to support port redundancy up to 2.5 Gbps. The high speed inputs are self-biased to about 1.3V and are designed for AC coupling. See Figure 7 for details. The inputs are compatible to most AC coupling differential signals such as LVDS, LVPECL and CML. The DS25MB200 is not designed to operate with data rates below 250 Mbps or with a DC bias applied to the CML inputs or outputs. Most high speed links are encoded for DC balance and have been defined to include AC coupling capacitors allowing the DS25MB200 to be directly inserted into the datapath without any limitation. The ideal AC coupling capacitor value is often based on the lowest frequency component embedded within the serial link. A typical AC coupling capacitor value ranges between 100 and 1000nF. Some specifications with scrambled data may require a larger capacitor for optimal performance. To reduce unwanted parasitics around and within the AC coupling capacitor, a body size of 0402 is recommended. Figure 6 shows the AC coupling capacitor placement in an AC test circuit. 4 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: DS25MB200 DS25MB200 www.ti.com SNLS220G – MARCH 2006 – REVISED APRIL 2013 Each input stage has a fixed equalizer that provides equalization to compensate about 5 dB of transmission loss from a short backplane trace (about 10 inches backplane). The output driver has Pre-emphasis (driver-side equalization) to compensate the transmission loss of the backplane that it is driving. The driver conditions the output signal such that the lower frequency and higher frequency pulses reach approximately the same amplitude at the end of the backplane, and minimize the deterministic jitter caused by the amplitude disparity. The DS25MB200 provides four steps of user-selectable Pre-emphasis ranging from 0, -3, -6 and –9 dB to handle different lengths of backplane. Figure 2 shows a driver Pre-emphasis waveform. The Pre-emphasis duration is 188ps nominal, corresponds to 0.47 bit-width at 2.5 Gbps. The Pre-emphasis levels of switch-side and line-side can be individually programmed. Table 1.

An example is the output skew among data paths from SIA_0± to LO_0±, SIB_0± to LO_0±, SIA_1± to LO_1± and SIB_1± to LO_1±. Another example is the output skew among data paths from LI_0± to SOA_0±, LI_0± to SOB_0±, LI_1± to SOA_1± and LI_1± to SOB_1±. tSKO also refers to the delay skew of the loopback paths of the same port and between similar data paths between port 0 and port 1. An example is the output skew among data paths SIA_0± to SOA_0±, SIB_0± to SOB_0±, SIA_1± to SOA_1± and SIB_1± to SOB_1±. Device output random jitter is a measurement of the random jitter contribution from the device. It is derived by the equation sqrt(RJOUT2– RJIN2), where RJOUT is the random jitter measured at the output of the device in psrms, RJIN is the random jitter of the pattern generator driving the device. Device output deterministic jitter is a measurement of the deterministic jitter contribution from the device. It is derived by the equation (DJOUT–DJIN), where DJOUT is the peak-to-peak deterministic jitter measured at the output of the device in pspp, DJIN is the peak-topeak deterministic jitter of the pattern generator driving the device. For operation under 1 Gbps, encoded data transmission is recommended (i.e. 8b10b).

Receiver Input Termination and Biasing Circuit APPLICATION INFORMATION The DS25MB200 input equalizer provides equalization to compensate about 5 dB of transmission loss from a short backplane transmission line. For characterization purposes, a 25-inch FR4 coupled micro-strip board trace is used in place of the short backplane link. The 25-inch microstrip board trace has approximately 5 dB of attenuation between 375 MHz and 1.875 GHz, representing closely the transmission loss of the short backplane transmission line. The 25-inch microstrip is connected between the pattern generator and the differential inputs of the DS25MB200 for AC measurements.
