Transmission Characteristics (Continued)

Unless otherwise noted, limits printed in BOLD characters are guaranteed for V

CC = +5V ±5%,VBB = −5V ±5%;TA = 0˚C to

+70˚C (−40˚C to +85˚C for TP3070-X) by correlation with 100% electrical testing at T

A = 25˚C. f = 1015.625 Hz, VFXI =

0 dBm0, D

R0orDR1 = 0 dBm0 PCM code. Transmit and receive gains programmed for maximum 0 dBm0 test levels (0 dB

gain), hybrid balance filter disabled. All other limits are assured by correlation with other production tests and/or product de-

sign and characterization. All signals referenced to GND. Typicals specified at V

CC = +5V, VBB = −5V, TA = 25˚C.
