TS8388B Main Timing Information
Timing Value TS8388B Timing values defined Table page advanced data, issued from electric simulations first characterizations results fitted with measurements. Timing values given package inputs/outputs, taking into account package internal controlled impedance traces propagation delays, gullwing model, specified termination loads. Propagation delays 50/75 impedance traces taken into account TDR. Apply proper derating values corresponding termination topology. min/max timing values valid over full temperature range following conditions: Specified Termination Load (Differential output Data Data Ready): resistor parallel with standard ECLinPS register from Motorola (i.e.: 10E452) Typical ECLinPS inputs shows typical input capacitance (including package protections). addressing output Dmux, take care some Digital outputs have same termination load apply corresponding derating value given below.

Apply proper time delay derating value different dielectric layer used.

TSEV8388B Evaluation Board, propagation time delay ps/mm (155 ps/inch) corresponding GHz) dielectric constant RO4003 used Board. different dielectric layer used (for instance Teflon), please appropriate propagation time values. does depend propagation times because differential data time difference between Data Ready output delay digital Data output delay). also most straightforward data measure, again because differential: measured directly onto termination loads, with matched Oscilloscopes probes.
TOD-TDR Variation Over Temperature
Values track each other over temperature variation TOD-TDR 100°C temperature variation). Therefore TOD-TDR variation over temperature negligible. Moreover, internal (on-chip) package skews between each Data TODs effect considered negligible.

However, external TOD-TDR values dictated total digital datas skews between every TODs (each digital data) TDR: Board, bonding wires output lines lengths differences, output termination impedance mismatches.

Principle Operation
Analog input sampled rising edge external clock input (CLK, CLKB) after (aperture delay) typically digitized data available after clock periods latency (pipeline delay (TPD)), clock rising edge, after 1360 typical propagation delay TOD. Data Ready differential output signal frequency (DR, DRB) half external clock frequency, that switches same rate digital outputs. Data Ready output signal (DR, DRB) switches external clock falling edge after propagation delay typically 1320 Master Asynchronous Reset input command DRRB (ECL compatible single-ended input) available initializing differential Data Ready output signal (DR, DRB). This feature mandatory certain applications using interleaved ADCs using single with demultiplexed outputs. Actually, without Data Ready signal initialization, impossible store output digital datas defined order.

Data Ready Output Signal Restart Data Ready output signal restarts DRRB command rising edge, logical high levels (-0.8V). DRRB also Grounded, allowed float, normal free running Data Ready output signal. Data Ready signal restart sequence depends logical level external encoding clock, DRRB rising edge instant: DRRB rising edge occurs when external encoding clock input (CLK, CLKB) LOW: Data Ready output first rising edge occurs after half clock period clock falling edge, after delay time 1320 already defined hereabove. DRRB rising edge occurs when external encoding clock input (CLK, CLKB) HIGH: Data Ready output first rising edge occurs after clock period clock falling edge, delay 1320

Noise Immunity Information
Circuit noise immunity performance begins design level. Efforts have been made design order make device insensitive possible chip environment perturbations resulting from circuit itself induced external circuitry (Cascode stages isolation, internal damping resistors, clamps, internal (on-chip) decoupling capacitors). Furthermore, fully differential operation from analog input digital outputs provides enhanced noise immunity common mode noise rejection. Common mode noise voltage induced differential analog clock inputs will canceled these balanced differential amplifiers. Moreover, proper active signals shielding been provided chip reduce amount coupled noise active inputs. analog inputs clock inputs TS8388B device have been surrounded ground pins, which must directly connected external ground plane.
Digital Outputs
TS8388B differential output buffers internally loaded. resistors connected digital ground pins through -0.8V level shift diode (see Figure Figure Figure page 35). TS8388B output buffers designed driving (default) properly terminated impedance lines coaxial cables. bias current flowing alternately into resistors when switching ensures 0.825V voltage drop across resistor (unterminated outputs). VPLUSD positive supply voltage allows adjustment output common mode level from -1.2V (VPLUSD output compatibility) +1.2V (VPLUSD 2.4V LVDS output compatibility). Therefore, single-ended output voltages vary approximately between -0.8V -1.625V, (outputs unterminated), around -1.2V common mode voltage.

Three possible line driving back-termination scenarios proposed (assuming VPLUSD 0V): impedance transmission lines, differentially terminated (Figure 34): Each output voltage varies between -1.42V (respectively +1.4V +1V), leading ±0.41V 0.825V differential, around -1.21V (respectively +1.21V) common mode VPLUSD (respectively 2.4V). impedance transmission lines, differentially termination (Figure 35): Each output voltage varies between -1.02V -1.35V (respectively +1.38V +1.05V), leading ±0.33V differential, around -1.18V (respectively +1.21V) common mode VPLUSD (respectively 2.4V). impedance open transmission lines (Figure 36): Each output voltage varies between -1.6V -0.8V (respectively +0.8V +1.6V), which true levels, leading ±0.8V 1.6V differential, around -1.2V (respectively +1.2V) common mode VPLUSD (respectively 2.4V). Therefore, possible drive directly high input impedance storing registers, without terminating transmission lines. time domain, that means that incident wave will reflect transmission line output travel back generator (i.e.: data output buffer). buffer output impedance back reflection will occur.
Note: This longer true transmission line used, latter matching buffer output impedance.
Each differential output termination length must kept identical. recommended decouple midpoint differential termination with capacitor avoid common mode perturbation case slight mismatch differential output line lengths. large mismatches (keep differential line lengths will lead switching currents flowing into decoupling capacitor leading switching ground noise. differential output voltage levels termination) standard voltage levels, however possible drive standard logic circuitry like ECLinPS logic line from Motorola®. sampling rates exceeding GSPS, difficult trigger Acquisition System with digital outputs. becomes necessary regenerate digital data Data Ready means external amplifiers, order able test TS8388B optimum performance conditions.
