MANUFACTURER DATA REVIEW
Key technical specifications
Ordering-code highlights reviewed against official manufacturer documentation.
- Function
- Differential-input to two-output LVCMOS clock buffer and voltage translator · independent input and output supply rails
- Input supply (VDDIN)
- 1.8 V, 2.5 V or 3.3 V nominal ±10% · operating ranges 1.62 V to 1.98 V, 2.25 V to 2.75 V, 2.97 V to 3.63 V
- Output supply (VDDO)
- 1.2 V, 1.5 V or 1.8 V nominal ±10% · operating ranges 1.08 V to 1.32 V, 1.35 V to 1.65 V, 1.62 V to 1.98 V
- Input frequency
- 0 MHz to 250 MHz · this fIN_D row is tabulated under the data sheet’s DC-coupled differential input conditions (Input Electrical Characteristics, §1.0); VID 0.2 V minimum, input slew rate 0.6 V/ns minimum under the same conditions. The pin table (Table 2-1) states the range as >0 Hz to 250 MHz and notes the device transfers a DC level once the outputs are enabled; AC-coupled drive is the §3.1 interface shown for LVDS and LVPECL sources, while HCSL is DC-coupled natively
- Propagation delay
- 1.2 ns typical · 0.9 ns minimum / 2.3 ns maximum, input to output
- Output-to-output skew
- 20 ps maximum · across the datasheet output-characteristics conditions (VDDIN = 1.8 V to 3.3 V, VDDO = 1.2 V to 1.8 V, TA = −40°C to +105°C)
- Additive jitter
- 34.2 fsRMS typical / 37.3 fsRMS maximum · 12 kHz to 20 MHz at VDDIN = 3.3 V, VDDO = 1.8 V, 156.25 MHz; worsens at VDDO = 1.2 V (38 fsRMS typical / 53.1 fsRMS maximum)
- Output impedance
- 40 Ω minimum / 50 Ω typical / 60 Ω maximum · the 50 Ω figure applies at VDDO = 1.2 V; at VDDO = 1.8 V the output impedance is slightly lower, approximately 40 Ω (Output Electrical Characteristics, Note 2). The data sheet describes the outputs as having built-in 50 Ω series resistance (at 1.2 V VDDO, Table 2-1) that makes them suitable for driving 50 Ω transmission lines without external components (§3.0, §3.2)
- Input supply current
- 4.8 mA typical · VDDIN = 3.3 V, outputs disabled, 25 MHz input clock
- Absolute maximum ratings
- VDDIN −0.5 V to +4.0 V and VDDO −0.5 V to +2.3 V are absolute-maximum figures, not operating ranges
- Order-code package
- 8-lead VDFN (TWL), 1.4 mm × 1.6 mm, wettable flank · the only order code in DS20007132B; the −TR suffix is an ordering identifier and is not printed on the package
- Manufacturer packing
- Tape and reel, 2,000 per reel · packing quantity, not stock or MOQ
