TS5070 - TS5071
TRANSMISSION CHARACTERISTICS
Unless otherwise noted, limits printed in BOLD
characters are guaranteed for V_CC = + 5 V ± 5 % ;
VSS = – 5 V ± 5 %, TA =-40 °C to 85 °C by correlation
with 100 % electrical testing at TA = 25 °C (-40°C
to 85°C for TS5070-X and TS5071-X).
f = 1031.25 Hz, VFXI = 0 dBm0, DR0 or 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.
