19 / 26 page  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. Symbol Parameter Conditions Min Typ Max Units AMPLITUDE RESPONSE G RAL Receive Gain Sinusoidal Test Method.
