20 / 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 NOISE PPSR R Positive Power Supply PCM Code Equals Positive Zero Rejection, Receive V CC = 5.0 VDC + 100 mVrms Measure VF RO f = 0 Hz–4000 Hz 36 dBC f = 4 kHz–25 kHz 40 dB f = 25 kHz–50 kHz 36 dB NPSR R Negative Power Supply PCM Code Equals Positive Zero Rejection, Receive V BB = −5.0 VDC + 100 mVrms Measure VF RO f = 0 Hz–4000 Hz 36 dBC f = 4 kHz–25kHz 40 dB f = 25 kHz–50 kHz 36 dB SOS Spurious Out-of-Band 0 dBm0, 300 Hz to 3400 Hz Input PCM Signals at the Channel Code Applied at D R0 (or DR1) Output 4600 Hz–7600 Hz −30 dB 7600 Hz–8400 Hz −40 dB 8400 Hz–50,000 Hz −30 dB DISTORTION STD X Signal to Total Distortion Sinusoidal Test Method STD R Transmit or Receive Level = 3.0 dBm0 33 dBC Half-Channel, µ-law Selected = 0 dBm0 to − 30 dBm0 36 dBC = −40 dBm0 30 dBC = −45 dBm0 25 dBC STD RL Signal to Total Distortion Sinusoidal Test Method Receive with Level = +3.1 dBm0 Resistive Load R L = 600Ω,GR = −0.5 dB 33 dBC R L = 300Ω,GR = −1.2 dB 33 dBC SFD X Single Frequency −46 dB Distortion, Transmit SFD R Single Frequency −46 dB Distortion, Receive IMD Intermodulation Distortion Transmit or Receive Two Frequencies in the Range −41 dB 300 Hz–3400 Hz www.national.com 20 |
