IDT5T9306 2.5V LVDS 1:6 CLOCK BUFFER TERABUFFER™ II FEATURES: DESCRIPTION: • • • • • • • • The IDT5T9306 2.5V differential clock buffer is a user-selectable differential input to six LVDS outputs. The fanout from a differential input to six LVDS outputs reduces loading on the preceding driver and provides an efficient clock distribution network. The IDT5T9306 can act as a translator from a differential HSTL, eHSTL, LVEPECL (2.5V), LVPECL (3.3V), CML, or LVDS input to LVDS outputs. A single-ended 3.3V / 2.5V LVTTL input can also be used to translate to LVDS outputs. The redundant input capability allows for an asynchronous change-over from a primary clock source to a secondary clock source. Selectable reference inputs are controlled by SEL. The IDT5T9306 outputs can be asynchronously enabled/disabled. When disabled, the outputs will drive to the value selected by the GL pin. Multiple power and grounds reduce noise. • • • • Guaranteed Low Skew < 25ps (max) Very low duty cycle distortion < 125ps (max) High speed propagation delay < 1.75ns (max) Additive phase jitter, RMS 0.159ps (typical) @ 125MHz Up to 1GHz operation Selectable inputs Hot insertable and over-voltage tolerant inputs 3.3V / 2.5V LVTTL, HSTL, eHSTL, LVEPECL (2.5V), LVPECL (3.3V), CML, or LVDS input interface Selectable differential inputs to six LVDS outputs Power-down mode 2.5V VDD Available in VFQFPN package APPLICATIONS: • Clock distribution FUNCTIONAL BLOCK DIAGRAM GL G PD A1 A2 0 SEL IDT™ / ICS™ LVDS CLOCK BUFFER TERABUFFER™ II Q1 OUTPUT CONTROL Q2 OUTPUT CONTROL Q3 OUTPUT CONTROL Q4 OUTPUT CONTROL Q5 OUTPUT CONTROL Q6 Q1 Q2 1 A1 A2 OUTPUT CONTROL 1 Q3 Q4 Q5 Q6 IDT5T9306 REV.

A[1:2] is the "true" side of the differential clock input. Complementary clock inputs. A[1:2] is the complementary side of A[1:2]. For LVTTL single-ended operation, A[1:2] should be set to the desired toggle voltage for A[1:2]: 3.3V LVTTL VREF = 1650mV 2.5V LVTTL VREF = 1250mV Gate control for differential outputs Q1 and Q1 through Q6 and Q6. When G is LOW, the differential outputs are active. When G is HIGH, the differential outputs are asynchronously driven to the level designated by GL(2). Specifies output disable level. If HIGH, "true" outputs disable HIGH and "complementary" outputs disable LOW. If LOW, "true" outputs disable LOW and "complementary" outputs disable HIGH. Clock outputs Complementary clock outputs Reference clock select. When LOW, selects A2 and A2. When HIGH, selects A1 and A1. Power-down control. Shuts off entire chip. If LOW, the device goes into low power mode. Inputs and outputs are disabled. Both "true" and "complementary" outputs will pull to VDD. Set HIGH for normal operation.(3) Power supply for the device core and inputs Power supply return for all power No connect; recommended to connect to GND NOTES: 1. Inputs are capable of translating the following interface standards: Single-ended 3.3V and 2.5V LVTTL levels Differential HSTL and eHSTL levels Differential LVEPECL (2.5V) and LVPECL (3.3V) levels Differential LVDS levels Differential CML levels 2. Because the gate controls are asynchronous, runt pulses are possible. It is the user's responsibility to either time the gate control signals to minimize the possibility of runt pulses or be able to tolerate them in down stream circuitry. 3. It is recommended that the outputs be disabled before entering power-down mode. It is also recommended that the outputs remain disabled until the device completes powerup after asserting PD. 4. The user must take precautions with any differential input interface standard being used in order to prevent instability when there is no input signal.
