TRANSMISSION CHARACTERISTICS

Unless otherwise noted, limits printed in BOLD

characters are guaranteed for VCC =+5 V

± 5% ;

VSS =– 5 V

± 5%, TA =-40°Cto 85 °C bycorrelation

with 100 % electrical testing at TA =25

°C (-40°C

to 85

°C for TS5070-Xand TS5071-X).

f = 1031.25 Hz, VFXI = 0 dBm0, DR0or DR1= 0

dBm0 PCM code, Hybrid Balance filter disabled. All

other limits are assured by correlation with other

production tests and/or product design and char-

acterization. All signals referenced to GND. dBm

levels are into 600 ohms. Typicals specified at

VCC =+5 V, VSS =-5 V, TA =25

°C.
