2 / 28 page 2001 Jun 25 2 Philips Semiconductors Product specification 2.5 Gbits/s postamplifier with level detector TZA3014 FEATURES • Single 3.3 V power supply • Wideband operation from 50 kHz to 2.5 GHz (typical value) • Fully differential • On-chip DC-offset compensation without external capacitor • Interfacing with supplied positive or negative logic • Positive Emitter Coupled Logic (PECL) or Current-Mode Logic (CML) compatible data outputs adjustable from 200 to 800 mV (p-p) single-ended • Power-down capability for unused output or detector • Rise and fall times of 80 ps (typical value) • Inverted output possible • Input level detection circuit for Received Signal Strength Indicator (RSSI) and Loss Of Signal (LOS), programmable from 0.4 to 400 mV (p-p) single-ended, with open-drain comparator output for directly interfacing positive or negative logic • Reference voltage for output level and LOS adjustment • HTQFP32 and HBCC32 plastic packages with exposed pad • Mute input. APPLICATIONS • Postamplifier for SDH/SONET transponder • SDH/SONET wavelength converter • PECL driver • Fibre channel arbitrated loop • Signal level detectors • Swing converter CML 200 mV (p-p) to PECL 800 mV (p-p) • 2.5 GHz clock amplification. GENERAL DESCRIPTION The TZA3014 is a low gain postamplifier with a LOS detector and a RSSI designed for use in critical signal path control applications, such as loop-through or Wavelength Division Multiplexing (WDM). The signal path is capable of operating from 50 kHz up to 2.5 GHz. The TZA3014 can be delivered in HTQFP32 and HBCC32 packages and as bare die.
