8 / 18 page TDA1302_1 9 Wed Sep 14 13:30:56 1994 September 1994 9 Philips Semiconductors Preliminary specification Data amplifier and laser supply circuit for CD player and read only optical systems TDA1302T Notes to the characteristics 1. The maximum input current is defined as the current in which the gain reaches its minimum. Increasing the supply voltage to VDD = 5 V increases the maximum input current (see also Figs 4 and 5). 2. The gain increases if a larger supply voltage is used (see also Fig.6). 3. Icsin is the sum of the diode input currents 1 to 4; Itsin is the sum of the diode input currents 5 and 6. 4. Transresistance 120 k Ω means LOW gain, selected if HG = logic 0 (see Table 1). 5. Transresistance 240 k Ω means HIGH gain, selected if HG = logic 1 (see Table 1). 6. Output voltage swing will be: VSRRF = VRFMO = VRFO(p-p). 7. Refers to equalized output only. 8. For single speed the gain ratio is defined as gain difference between 1 MHz and 100 kHz, while the flatness delay is defined up to 1 MHz (see also Fig.7). For double speed the gain ratio is defined as gain difference between 2 MHz and 200 kHz, while the flatness delay is defined up to 2 MHz. Transfer function The equalized amplifier including Cext and Rext has the following transfer functions, where ‘rfe’ refers to equalized output only and ‘rf’ refers to equalized and not equalized outputs. FOR SINGLE SPEED (SP = LOGIC 1) (1) FOR DOUBLE SPEED (SP = LOGIC 0) (2) The denominator forms the denominator of a Bessel low-pass filter. Table 2 Transresistance. SYMBOL DESCRIPTION TYP.
