GTLP10B320 10-Bit LVTTL/GTLP Transceiver with Split LVTTL Port and Feedback Path May 2001 Revised May 2001 GTLP10B320 10-Bit LVTTL/GTLP Transceiver with Split LVTTL Port and Feedback Path General Description The GTLP10B320 is a 10-bit Universal bus driver and receiver, with separate LVTTL inputs and outputs and a feedback path for diagnostics, that provides LVTTL to GTLP signal level translation. High speed backplane operation is a direct result of GTLP’s reduced output swing (2000V −65°C to +150°C Note 5: Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the “Electrical Characteristics” table are not guaranteed at the absolute maximum rating. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Note 6: IO Absolute Maximum Rating must be observed. DC Electrical Characteristics Over Recommended Operating Free-Air Temperature Range, VREF = 1.0V (unless otherwise noted).

Note 9: This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND. Note: GTLP V REF and VTT are specified to 2% tolerance since signal integrity and noise margin can be significantly degraded if these supplies are noisy. In addition, VTT and RTERM can be adjusted beyond the recommended operating to accommodate backplane impedances other than 50Ω, but must remain within the boundaries of the DC Absolute Maximum Ratings. Similarly, VREF can be adjusted to optimize noise margin. AC Operating Requirements Over recommended ranges of supply voltage and operating free-air temperature, VREF = 1.0V (unless otherwise noted).

The specifications are given for specific worst case VCC and temperature and apply to any outputs switching in the same direction either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH) or in opposite directions both HL and LH (tOST). This parameter is guaranteed by design and statistical process distribution. Actual skew values between the GTLP outputs could vary on the backplane due to the loading and impedance seen by the device. Note 15: tPV - Part to part skew is defined as the absolute value of the difference between the actual propagation delay for all outputs from device to device. The parameter is specified for a specific worst case VCC and temperature. This parameter is guaranteed by design and statistical process distribution. Actual skew values between the GTLP outputs could vary on the backplane due to the loading and impedance seen by the device. Note 16: Due to the open drain structure on GTLP outputs tOST and t PV(LH) in the A-to-B direction are not specified. Skew on these paths is dependent on the VTT and RT values on the backplane. www.fairchildsemi.com 10 GTLP10B320 Test Circuits and Timing Waveforms Test Circuit for A Outputs Test Circuit for B Outputs Test tPLZ/tPZL S 6V tPLH/tPHL Open tPHZ/tPZH GND Note A: CL includes probes and Jig capacitance.
