NB7VPQ16M: Pre-Emphasis Copper / Cable Driver, 12.5 Gbps, Programmable, 1.8 V / 2.5 V, with Selectable Equalizer Receiver

  • The NB7VPQ16M is a high performance single channel programmable Pre-Emphasis CML Driver with an Equalizer Receiver, signal enhancer, that operates up to 12.5 Gbps with a 1.8 V or 2.5 V power supply. When placed in series with a Data/Clock path, the NB7VPQ16M inputs will compensate the degraded signal transmitted across a FR4 PCB backplane or cable interconnect. Therefore, the serial data rate is increased by reducing Inter-Symbol Interference, ISI, caused by losses in copper interconnect or long cables. The Pre-Emphasis buffer is controlled using a serial bus via the SDIN, Serial Data In, and SCLKIN, Serial Clock In, control inputs and contains circuitry which provides sixteen programmable Pre-Emphasis settings to select the optimal output compensation level. These selectable output levels will handle various backplane lengths and cable lines. The first four SDIN bits, D3:D0, will digitally select 0dB through 12dB of de-emphasis. For cascaded applications, the shifted SDIN and SCLKIN signals are presented at the SDOUT and SCLKOUT pins. The 5th-bit, LSB, of the serial data bits allows for enabling the equalization function of the receiver. The differential Data/Clock inputs incorporate a pair of internal 50-ohm termination resistors, in a 100-ohm center-tapped configuration, via the VT pin and will accept LVPECL, CML or LVDS logic levels. This feature provides transmission line termination on-chip, at the receiver end, eliminating external components.
